The technical field to which the invention relates.

The present invention relates to the color combination, in particular to the application of the coating composition, which mainly provides a uniform visual characteristics of the products, containing a variety of material substrates.

The level of technology

There are many products that are made from different types of components that connect together. It is often desirable to maintain uniformity of color among the various components. However, when the components are made of materials of different types, it is difficult to ensure the same visual appearance.

For example, shoes, such as sneakers, often contains various types of materials, including natural leather, synthetic leather, vinyl, fabric, foam and rubber. For each type of substrate material using various compositions of the coating. For example, one type of coating can be applied on parts of uppers of leather, other type of coating may be applied to components of the Shoe upper made of synthetic leather. Moreover, it is customary to include the pigments in foam soles of such footwear to match the color of the sole and/or to ensure the uniformity and/or harmonizing color between the top of the Shoe and sole. The use of such complex specialized coatings and pigments leads to otnositelno complex and expensive production methods and can also cause the need to "color adjustment" of different coatings.

The adjustment color is the way in which the visual characteristics of more than one coverage "equalize" in such a way that two or more coatings have the same or essentially the same appearance. The color adjustment may be desirable when, for example, two different substrates of the same products are covered with two different coatings. The color adjustment may also be desirable when trying to determine the coverage that is appropriate to the pre-coated products or components. For example, automobile workshops often paint the repaired areas of the body compositions of coatings, matching in color to the original color of the body; such selected by the color of the coatings often have a composition different from the composition of the original coating, and can represent very different types of coatings, such as vozdushnootopitel coverage compared to thermoset coatings.

While selected color components may have essentially the same appearance under certain conditions of observation and illumination, they may not retain the same appearance, for example, when the angle changes when changing the spectral composition of the light source and/or when the floor is aging. For example, some selected color components can have the same in Asni view in daylight, but may not be the same as under the fluorescent lighting and/or tungsten lighting. When comparing the color depends on the lighting conditions or observations, the adjustment referred to as the conditional or "one metameric".

It would be desirable to provide a coating composition capable of covering the different types of substrates, products, at the same time eliminating the need for color adjustment.

The implementation of the invention

The present invention provides a color combination for products containing two or more components of different materials or substrates. "Color mix" and similar terms refer to the use of similar or essentially similar compositions of the coatings in order to provide essentially uniform color characteristics of two or more types of substrates under the influence of more than one light conditions. "Floor color combination" is a coating that exhibits such essentially uniform color characteristics. Cover with color combination can be used to cover two or more the components of the product, to provide essentially uniform color for a variety of components and thus to prevent problems and/or work associated with conventional methods of selecting a color.

According to the embodiment of the present invention, at least one of the components contains an elastic substrate. Used herein, the term "flexible substrate" refers to a substrate that can be subjected to mechanical loads, such as bending, stretching, compression and the like, without significant irreversible changes. Examples of flexible substrates include natural leather, synthetic leather, processed natural skin treated with synthetic leather, suede, vinyl, nylon, ethylenevinylacetate foam (EVA foam), thermoplastic urethane (TPU), bubbles with the liquid, polyolefins and mixtures of polyolefins, polyvinyl acetate and copolymers, polyvinyl chloride and copolymers, urethane elastomers, synthetic fabrics and natural fabrics.

In a non-limiting embodiment, at least one elastic substrate product may contain foam. Used herein, the term "foam substrate" means a polymer and/or natural material, which contains a multitude of open and/or closed cells. Examples of foam substrates include polystyrene foam, polymethacrylimide foam, polyvinylchloride foam, poliuretanovye, polypropylene foam and polyethylene foam. Examples of olefinic foams include polypropylene, ethylene, vinyl acetate (EVA) and polyethylene foam.

In a non-limiting embodiment of the present invention, the product includes shoes. Used herein, the term "footwear includes sneakers and sports shoes, mens and womens fashion shoes, mens and womens casual shoes, children's shoes, sandals, Slippers, boots, work shoes, street shoes, orthopedic shoes, sneakers and similar footwear. Examples of components of footwear includes a sole, the inner sole, the materials of the upper and lining. As a separate unlimited example athletic shoes may contain natural leather, synthetic leather and/or fabric tops shoes and EVA foam backing.

Figure 1 illustrates sneakers, containing many components made of materials of different types, which can be covered with a coating with a color combination in accordance with an embodiment of the present invention. Polubotok 10 includes a workpiece 12 top, a sole 14 and the insole 16. The workpiece 12 to the top of polybutene 10 includes various parts such as the tibia 22, a back 24, a toe 26, vamp 27, the hole for the strap 28 and the tongue 29. In accordance with generally accepted design of shoes and the technology of its manufacture different parts of the top of Polus Tinka 10 can be made of materials of different types. For example, tibia 22 may contain natural leather, the heel 24 may contain TPU toe 26 may contain synthetic leather, vamp 27 may contain natural leather, the hole for the strap 28 may include nylon, and the tongue 29 can contain synthetic leather or fabric. These various components can be connected together using technologies such as sewing, gluing and the like.

The sole 14 and shank 16 polybutene 10 can be made of materials of different types, which are usually different from the material of the workpiece 12 top. For example, the sole 14 may be made of rubber or similar material, while the insole 16 may contain a foam substrate, such as EVA foam and the like as listed above.

In addition to providing essentially uniform visual characteristics among the various components of the workpiece 12 top it is often desirable to provide a uniform visual characteristics between the insole 16 and at least one of the components of the top 12. Moreover, in some types of footwear it is advisable to provide essentially uniform visual characteristics between the sole 14 and the insole 16 and/or to provide a basically uniform visual characteristics between the sole 14 and at least some parts of the top 12.

The conventional method of manufacturing a Shoe covered with the eating includes each component, fabricated and painted separately, usually from different vendors and/or with different coatings. This creates several disadvantages. The timing of the development of production, the need to make changes, should be so great that all providers could choose the necessary color and deliver the required number. When different suppliers produce materials, the method of forming color may vary. Common components of the shoes may have different shades of color depending on the lighting, even if the color was originally agreed. The use of different methods of application of different coatings can degrade the color adjustment between components.

In accordance with an embodiment of the present invention coated with the color combination may be applied to at least two different component of the Shoe containing various substrates, such as shown in figure 1, in order to provide the desired uniform visual characteristics without requiring color selection. This way color combinations can provide one or more advantages over conventional methods of composition shoes, uniform coating systems, which can be used to cover the various components of the substrate shoes. As a result, the cycle time of the production of footwear m which can be greatly reduced, since all of the substrate shoes can be ordered in standard color, such as white or black. Manufacturer of shoes can be painted with all components in the same paint, using the same methods. Also, the components of the shoes may be covered with the formation of desirable colors needed for shoes. These methods can also be used for the production of small batches of shoes having a unique color and/or visual effect. Also, because the same coating can be deposited on the various components of the substrate shoes, they have good color harmony in all lighting conditions. In addition, any fading of color by wearing or cleaning can be substantially homogeneous for different substrates and, thus, to maintain color harmony over time socks.

In addition to shoes other examples of products that can be subjected to the color combination in accordance with embodiments of the present invention include automotive upholstery, car interiors, upholstery, hand bags, clothing, outerwear, wallets, caps wheel, Luggage, suitcases, sports goods, sports equipment and the like. For example, automotive or upholstery may contain a combination of components of natural leather and synthetic leather, which can b shall be covered with a coating with a color combination in accordance with an embodiment of the present invention.

Used herein, the term "coating" means a material that forms a mostly solid surface layer or film on the outer surface of the substrate. The coating thickness measured from the surface of the substrate. In some embodiments a portion of the coating can penetrate at least partially into the substrate. For example, the coating can penetrate at least partially into the pores of the skin or foam substrate. It is clear that the coatings of the present invention is sprayed or otherwise precipitated on the substrate, which may or may not have other coatings, and they are not applied as a laminate, as well as not put on lining paper and not transferred into the substrate. Thus, the application of the present coating compositions can reduce the working time.

Cover with the color combination of the present invention can be applied to the substrate by any known method of coating. Examples of coating methods include spraying, slit coating, the coating roller, the coating applied by spray, dipping, screen printing, brush application or coating to remove excess using a strap. In some embodiments the coating is applied mostly all whole outer surface of the substrate. In other embodiments, the coating is applied to the area of the external surface of the substrate.

In one embodiment of the present invention the composition of the coating color combination is an aqueous coating containing aqueous polymer dispersion and a colorant. In some embodiments, the composition of the aqueous coating can be mostly without solvent. The term "mostly without solvent"used herein means that the composition is ocrite contains less than about 15 or 20 weight percent of organic solvents, for example, less than 5 or 10 weight percent relative to the total weight of the composition, coated on a substrate. For example, the coating composition may contain from zero to 2 or 3 weight percent of organic solvents.

The term "water"used herein means a coating composition in which the liquid carrier composition is essentially water in mass percent, i.e. more than 50 mass percent of the medium contains water. The rest of the media contains less than 50 mass percent of an organic solvent, usually less than 25 mass%, for example less than 15 mass percent. Based on the total weight of the coating composition (including the media and solid) water may be from about 20 to about 80 weight percent, usually from about 30 to about 70 weight percent, of the total composition.

Composition mostly without solvent, the aqueous coating composition of some embodiments of the present invention include polyurethane dispersion. Any polyurethane polymers, which form a suitable film and combined with compositions based on water, can be applied in accordance with these embodiments of the present invention. Suitable polyurethane polymers include polymers formed from MDI, active hydrogen-containing Mat is real, such as polyol, polyester, polycarbonate, polyamide, polyurethane, polyurea, polyamine, polyolefin, siloxane polyol, and/or mixtures thereof, the material with the acid functional groups having a functional group reactive with isocyanate and, optionally, with polyamines. Some examples of polymers that may be suitable for use in the present coating compositions described in US no 5939491 that is entered into the description by reference.

Film-forming polyurethane polymers are typically present in the coating in amounts greater than about 20 weight percent, for example, more than about 40 weight percent and less than 90 mass percent of the total solid mass of the cured coating. For example, the content of the polymer can be between 20 and 80 mass%. In one non-limiting embodiment, the polyurethane has an average molecular weight of at least 10,000, for example, at least 25,000 or 100,000 or higher. The polyurethane polymer in some embodiments has a hydroxyl number less than about 10, such as about 5, such as about 3.

In one unlimited embodiment of di - and/or trifunctional acrylics, polyesters, polyethers, polycarbonates, polyamides, epoxy resins and/or vinyl can be added to replace part of the polyurethane dispersion is adnych compositions of the coatings. Suitable di - and/or trifunctional acrylic polymers may include unsaturated acrylic monomers and/or copolymers with vinyl monomers, obtained by emulsion polymerization. Suitable complex polyester polymers can include the reaction products of polyfunctional acids, anhydrides, polyfunctional alcohols and monofunctional acids and alcohols. Other suitable polymers include hybrids or mixtures of any of these polymers, such as acrylic/polyurethane, acrylic/polyester hybrid or mixture.

In yet another embodiment of the present invention can be applied polymer composition coating solvent-based. For example, the floor-based solvent may contain two components. In one embodiment, the first component may include a first polyester-polyol having a first functionality and a second polyester-polyol having a second functionality, where the second functionality more than the first. The second component contains an isocyanate. In some embodiments of the NCO:OH ratio of the composition of the coating can be 0.8:1 or higher. Suppose that two components, when combined, form a polyurethane coating.

In one embodiment the difference between the hydroxyl numbers of the first polyester-polyol and a second polyester-polyol is at least 10. In another in which the glassing the difference between the hydroxyl numbers of the first polyester-polyol and a second polyester-polyol is at least 20. In one embodiment, the first polyester-polyol of the first component has a low functionality. Used herein, the term "low functionality" means that the polyester-polyol has a hydroxyl number of less than about 65. Suitable polyester-polyol with a low functionality has a hydroxyl number of from about 40 to about 60. In one embodiment, the first polyester-polyol has a hydroxyl number of from about 54 to about 58. The low functionality of the first polyester-polyol leads to increased elasticity and a lower tendency to the formation of crosslinked linkages when reacted with isocyanate in the floor. Any polyester-polyol having a low functionality, can be used in the present invention. For example, the first polyester-polyol may be a reaction product of carboxylic acid and polyalcohol; such a product is commercially available as DESMOPHEN 1625A from Bayer Corporation.

In one embodiment, the second polyester-polyol of the first component has an average functionality. Used herein, the term "average functionality" means that the polyester-polyol has a hydroxyl number of from about 90 to about 125. In one embodiment, the second polyester-polyol has a hydroxyl number of from about 104 to about 118. The average functionality of the second polyester-polyol typically increases the density of crosslinking of the coating, the drive is to increase strength and improved chemical resistance. Any polyester-polyol having an average functionality can be used in the present invention. For example, the second polyester-polyol may be a reaction product of one or more polyols, one or more aromatic dicarboxylic acids and/or anhydrides and one or more aliphatic dicarboxylic acids and/or anhydrides. The second polyester-polyol may be a reaction product of isophthalic acid, phthalic anhydride, adipic acid, trimethylolpropane and 1,6-hexandiol; such a product is commercially available as DESMOPHEN 670 a-80 from Bayer Corporation. In one embodiment, the second polyester-polyol specifically excludes neopentylglycol.

The first and the second polyether-polyols can be connected with the formation of the polyester paleologou mixture in the first component. In one embodiment, the ratio of the first polyester-polyol and a second polyester-polyol to polyester polyol as one of the mixture is from about 5:1 to about 8:1. In yet another embodiment, the ratio of the first polyester-polyol and a second polyester-polyol to polyester polyol as one of the mixture is from about 6.5:1 to about 7.5:1. The number of the first polyester-polyol and the number of the second polyester-polyol in the mixture should be selected to optimize certain characteristics of each polyol. For example, an increased amount of the first polyester-polyol p is the increased elasticity, while the increased amount of the second polyester-polyol leads to increased strength and improved chemical resistance. The person skilled in the art can determine the best ratio on the basis of considerations depending on the needs of the consumer.

In one embodiment, the first polyester-polyol, the second polyester-polyol and one or more acrylic polyols can be combined with the formation of the first component. Acrylic polyol(s) may be added to the polyester polyol as one of a mixture of the first component to further enhance the strength of the coating. In one embodiment the acrylic polyol is an acrylic polyol modified with styrene. Examples of other suitable acrylic polyols include copolymers of methyl methacrylate with hydroxyquinoline (methyl)acrylate monomers, copolymers of isobornyl(meth)acrylate, copolymers of ethyl(meth)acrylate, hydroxyethyl(meth)acrylate and hydroxypropylmethacrylate. Acrylic polyol may have a functionality or to be essentially non-functional. In one embodiment of acrylic polyols used in the present invention typically have a hydroxyl number of at least about 50. In one embodiment, acrylic polyols, such as acrylic polyols modified with styrene can be added to the first component in the amount of up to eye is about 40 mass percent.

Acrylic polyols can be used in any amount which it is desirable to ensure sufficient strength of the coating. Acrylic polyols generally transversely crosslinked with isocyanates in the final coating, thereby increasing the density of the stitching and the hardness of the coating. Since increased amounts of acrylic polyols can increase the strength of the coating, but lower degree of elasticity, the required amount of the acrylic polyol may be determined based on the needs of the consumer.

The second component of a two-component coating may contain isocyanate. Used herein, the term "isocyanate" includes polyisocyanates and cyclic trimers of polyisocyanates. Suitable isocyanates include isophorone diisocyanate, 1,3-or 1,4-cyclohexane diisocyanate, dicyclohexylmethane diisocyanate, tetraallylsilane the diisocyanates such as m-tetramethylene diisocyanate, p-phenylene diisocyanate, polymethylene polyphenylisocyanate, 2,6-toluene diisocyanate, dianisidine diisocyanate, bicolored diisocyanate, naphthalene-1,4-diisocyanate, bis(4-isocyanatophenyl)methane, 4,4'-diphenylpropane diisocyanate, hexamethylene diisocyanate and trimerization hexamethylen diisocyanate.

The amount of the mixture of polyester-polyol and acrylic polyol, if it is used in the first component and the number of isocyanate in the second component due is to be selected to the ratio of isocyanate groups and hydroxyl groups, that is, the NCO:OH, have created a coating composition having a ratio of NCO:OH is higher than at least 0.8:1 or 1:1, such as at least 1.7:1, at least 2:1, at least 3:1. Without connection with any mechanism guess unreacted NCO groups can contact the surface of the elastic substrate, such as thermoplastic urethane, with the formation of elastic coatings with improved surface adhesion, scratch resistance, pencil hardness scale (groove) and/or the General curing properties.

As noted above, the dye may be in the form of a dispersion, including, but not limited to, dispersion of nanoparticles. Dispersion of the nanoparticles can include one or more highly dispersed nanoparticles of dyes or particles of dyes, which form a desired visible color and/or opacity and/or visual effect. Dispersion of the nanoparticles may include colorants, such as pigments or dyes having a particle size of less than about 150 nm, such as less than about 70 nm or less than about 30 nm. Nanoparticles can be formed by grinding the original organic or inorganic pigments with grinding media having a particle size of less than 0.5 mm Example dispersions of nanoparticles and methods for their preparation scribbled in US no 2003/0125417, which is introduced into the description by reference. Dispersion of the nanoparticles can also be produced by crystallization, precipitation, condensation from the gas phase and chemical grinding (i.e. partial dissolution). In order to minimize the re-agglomeration of the nanoparticles inside the cover, apply the dispersion of the nanoparticles coated with the polymer. Used herein, the term "dispersion of nanoparticles, coated with polymer" refers to a continuous phase in which the dispersed discrete "composite microparticles, which contain the nanoparticles and p is the polymer coating on the nanoparticles. Example dispersions of nanoparticles, coated with polymer, and methods for their production are disclosed in the application US 10/876315 filed June 24, 2004, which is entered into the description by reference, and divisional application US No. 60/482167 dated June 24, 2003, which is also entered here by reference.

Example compositions with a special effect that can be used in the present invention include pigments and/or compositions that produce one or more external effects such as reflection, pearl effect, metallic sheen, phosphorescence, fluorescence, photochromism, photosensitivity, thermochromism, goniochromism and/or color change. Additional compositions with special effects can provide other significant properties, such as opacity or texture. In a non-limiting embodiment of the composition with special effects can create change color, so the color of the coating changes when the floor see different angles of view. Examples of songs with a color effect is defined in US no 2003/0125416, which is introduced here by reference. Compositions with additional color effect may include a transparent coated mica and/or synthetic mica coated with silicon oxide, coated with aluminum oxide, a transparent liquid crystal pigment, a liquid crystal coating and/or any song where interference occurs due to the difference in the refractive indices inside the material as a result of the difference in the refractive indices between the surface material and air.

In one non-limiting embodiments of the photosensitive composition and photochromic composition that reversibly change color when exposed to one or more light sources, can be used in the coating of the present invention. Photochromic and/or photosensitive composition can be activated by irradiation with radiation of a given wavelength. When the composition becomes excited, the molecular structure is changed, and the changed structure reveals a new color that is different from the original color of the composition. When the irradiation of the radiation stop, photochromic and/or photosensitive composition can return to the rest state, in which the original color of the composition is returned. In one non-limiting embodiment of the photochromic and/or photosensitive composition may be colorless in the unexcited state, and to show color in the excited state. Full color change can occur within milliseconds to several minutes, for example from 20 seconds to 60 seconds. Examples of photochromic and/or photosensitive compositions include photochromic dyes.

In a non-limiting embodiment of the photosensitive composition and/or photochromic composition can be with whom are closely linked and/or, at least partially connected, for example, the covalent bond to the polymer and/or polymeric materials curable component. Unlike some of the coatings, in which the photosensitive composition can be moved from the coating into the substrate, the photosensitive composition and/or photochromic composition associated with and/or at least partially associated with the polymer and/or the polymerised component in accordance with non-limiting embodiment of the present invention, has a minimum movement of the cover. Examples of the photosensitive composition and/or photochromic compositions and methods for their preparation are given in the application US No. 10/892919, filed July 16, 2004 and which is introduced here as a reference. In General, the dye may be present in the coating composition in any amount sufficient to impart the desired visual and/or color effect. The dye may contain from 1 to 65 weight percent of the present compositions, for example from 3 to 40 weight percent or 5 to 35 weight percent of the total weight of the composition.

The present composition of the coatings with color combination can also optionally include other ingredients, such as staplers, fillers to reduce the cost, UV adsorbers, light stabilizers, plasticizers, surface-active substances is well, leveling means, adhesion promoters, rheology modifiers, light stabilizers of the type of spatial-obstructed amines (HALS) and wetting agents in a total amount up to 80 weight percent of the total weight of the composition, coated on a substrate. Suitable suturing may be selected by the person skilled in the art based on the chemical composition of the coating. Examples include carbodiimide, aminoplast polymers and penoplastovyj polymers and their mixtures, polyisocyanates and blocked polyisocyanates, anhydrides, polyepoxide, polyacid, a polyalcohol and polyamine. Carbodiimide water-based may be preferred in some aqueous coating compositions, since they do not contribute a significant amount of organic solvents in the coating composition. When using staplers, they are typically present in an amount up to about 50 weight percent of the total solid weight of the cured coating.

Additional optional additives to the coating includes a composition with the effect of smell, which give the coating the desired odor and/or limit undesirable odor over time. Examples of compositions with the effect of smell can include perfume additives, such as perfumes and/or colognes, and/or composition, masking the smell, such as deodorants. In non-limiting is oploschenii composition with the effect of smell may contain additives, which create or destroy the smell of new leather.

Other suitable components of coatings include one or more amplifiers textures that enhance the sense of surface and/or enhance the stability of the coating to resist stains. In one non-limiting embodiment of the amplifier texture coating gives the feeling of softness. Used herein, the term "smooth" means that the coated substrate exhibits an altered tactile property, such as simulated tactile feeling of velvet or leather to the touch. The amplifier textures can be additive which can be added to the composition of the coating, such as matting agents, silicon oxide and/or wax additives. Example matting agents from oxides of silicon may include ACEMATT OK 412 and ACEMATT TS 100, commercially available from Dedussa, Inc. Example wax additives may include oxide polytetramethylene, fluorinated waxes, and natural waxes such as paraffin wax and/or karnovsky wax. In another non-limiting embodiment of the amplifier texture can be introduced into the polyurethane polymer. For example, can be applied to components which provide a great plot softness" of the polyurethane. Examples include polytetramethylene ether glycol, commercially available under the name TERATHANE 2000 from Invista, Inc.

Coating color combination can b the th very elastic, so that the coating can be subjected to mechanical loads, such as bending, stretching and/or compression, without significant irreversible changes. In one non-limiting embodiment, when the cover is pressed, roll, fold and/or bend, the subsequent flaking scales, damage and/or visual change in the appearance of the coating is almost minimal. For example, when a flexible substrate coated with a coating, stretch or pressed, the coating color combination can save wear and/or deformation properties when returning the substrate to its original size and shape.

The following examples are intended to illustrate various aspects of the invention and are not intended to limit the scope of the invention.

EXAMPLE 7

This example demonstrates the relative change in color among the different systems (ASTM D2244-93) depending on the source color. System "A" represents the comparison of the red Shoe cover, described in example 3 synthetic leather (uppers), with the same coating material EVA foam (inner part of the foot). System "B" represents the comparison of two different equalizing color compositions on two different substrates: Envirobase 5502 equalizing color coating on synthetic leather and Global 5502 equalizing color coating on EVA foam. Two different 5502 coverage selected by colour to achieve the same color. Six different combinations (two systems × 3 source color) measured five times each to demonstrate that the observed change in relative color is not a function of measurement changes. In this example, all of the coating is applied by spraying. The properties of the Delta and (Δ), δ b (Δ b), Delta E (ΔΕ), and Delta L (ΔL) is measured on a Minolta spectrophotometer CM-3600d in accordance with CIELAB standards. For example, Δ is a measure of the extent to which the pattern is red or green. The results are shown in table 12. In the system, with two different is adjusted by color coatings, Δ adjustment color changes depending on the source color. More specifically, the color of each coating that can be read by a spectrophotometer, denser under fluorescent lighting than under fluorescent light or incandescent lamps. This demonstrates one of the problems associated with the adjustment of the color. In addition, for system a, which has the same coating on various substrates, color, read by the spectrophotometer, almost the same under all light sources.
