Vysokodekorativnye pigment, such thin plates, the method of its production and the interference colored pigments having metallic luster, based on it.

The technical FIELD of the INVENTION

The present invention relates to new vysokointensivnogo metallic pigment, such thin plates, method of its production, the interference colored pigments having metallic luster, on the basis of its application, etc.

BACKGROUND of INVENTION

Known commercially available pigments with mother-of-pearl luster, using such thin plates of mica substrates, coated with highly refractive metal oxides (hereinafter referred to as "interference color layer")such as titanium oxide, etc. in order to show color through the interference. However, since the translucent mica, the reflectivity is low; therefore, the expression of the interference colors under the influence of the interference is not completely achieved. Thus appeared the interference colored pigments, in which the metal being opaque and having a high optical reflectance, used as such thin plates of the substrate, with the coating of the interference color layer (such as xed titanium and others) on its surface (for example, JP (A) Hei. 1-110568, JP (A) Hei. 2-669, etc). In these interference colored pigments, the interference color is a layer, indirect, caused by the so-called Sol-gel method, with the exception of hydrothennal water treatment, such as thin plates of metal substrates have the disadvantage consisting in that they can easily react with water and can easily be oxidized.

Additionally, also known goniochromism pigments (multichromatic interference colored pigments), which on the surface such thin plates of metal substrates, the first coating layer is formed using hydrated oxide of silicon (as an example of a substance having a low refractive index), the so-called Sol-gel method, then put the second layer of metal oxide having a high refractive index, a vapor-phase reaction, and this procedure is repeated to obtain attractive effect (effect of the gradient) when the viewing angle changes (e.g. JP (A) Hei. 8-209024, JP (A) Hei. 8-302237, JP (A) Hei. 9-124971).

In addition, it is known that to obtain vysokointensivnogo layer (layer passivating) spend processing of the product phosphoric acid and the like, (for example, DE 19836810.0 etc), organic phosphoric acids (for example, JP (A) Hei. 3-74472, JP (PCT) 2001-502375, etc), only dioxido the silicon (for example, JP (A) Hei. 8-209025; US 2885366 and US 3954496; and so on)that perform the processing of vapor-phase method volatile phosphorus-containing compounds and volatile nitrogen-containing organosilicon compounds (JP (A) Hei. 7-292279), etc.

However, these standard methods, there is a drawback consisting in the fact that it is necessary to use expensive raw materials, or that are inherent smoothness of the surface of such thin plates of metal substrates remains unchanged, it is getting worse, or that insufficient distribution of the particles leads to uneven reflection, causing the reflected light on the surface of such a thin metal plates cannot be properly used. Thus, even when the upper interference color layer is additionally coated on top, it is impossible to sufficiently achieve the expression of the interference color.

In particular, because of neudovletvorennosti anti-corrosion properties against acidic aqueous solutions cannot be processed water systems, which involve low costs and favorable conditions of work. Namely, it is impossible to adopt a method in which a hydrated metal oxide obtained neutral hydrolysis using water-soluble metal salt and alkali, or thermal hydrolysis of water-soluble salts of metallov water system, cover, filtered off, dried and, if desired, calcined (this will be defined as a method of wet process in General, including in the claims). In addition, as mentioned above, smoothness and density of the surface, which caused the corrosion-resistant layer is insufficient, and the affinity between the layers of hydrated oxides of the metal components of such a corrosion-resistant layer, and a layer of hydrated oxides of the metal components of the interference color layers deposited after him, not because of what it is impossible to achieve homogeneity and density of the layer of hydrated oxide of the metal constituting the interference color layer; therefore it is impossible to achieve an interference color having a high color intensity.

In other cases, such as the use of gas-phase method (for example, in JP (A) Hei. 8-209024, JP (A) Hei. 8-302237, JP (A) Hei. 9-124971, etc), the disadvantages are the expensive cost of production plant, the limit used in the method of the evaporation temperature (JP (A) 7-292279), which is why, in General, require a more strict control of reaction than the reaction in the aqueous phase, etc. Thus, there is a need in the application of the above standard method, which is a so-called wet process.

WAYS of carrying out the INVENTION

Further, the present invention will be explained in more detail together with the way to obtain.

Such thin plates of metal substrates used in the present invention are so-called metal pigments that contain such thin plates of metals and alloys of metals.

Specific examples of the flakes include aluminum flakes, titanium flakes, gold flakes, silver flakes, copper flakes-zinc alloy, iron flakes, bronze flakes, flakes, stainless steel flakes, bronze-aluminum alloy, scales of various aluminum alloys, scales R is slichnih titanium alloys, etc. Preferred flakes include aluminum flakes, titanium flakes, gold flakes, silver flakes, copper flakes-zinc alloy flakes of stainless steel, bronze flakes, etc.; most preferred scales include widely sold shiny metallic pigments such as aluminum flakes (for example, the following manufacturers: Silberline; Showa Aluminum Co., Ltd.; Toyo Aluminum Co., Ltd.; Asahi Kasei Metals Co., Ltd.; Eckart-Werke, etc.), titanium flakes, flakes of stainless steel, etc. that are commercially available; and the most preferred are aluminum flakes.

Among them can be used such thin plates of metal substrates that are commercially available in various States, such as the scales of the substrate, which were suspendirovanie in an organic solvent, to prevent oxidative corrosion caused by humidity, which is in the air (for example, pigment paste, suspended in mineral spirit, etc), those substrates which, with the goal of exfoliation or improve the dispersion was coated in various types of surface treatment and suspended in an organic solvent, and the substrate, the surface of which had previously caused a protection film oxidation (the passivation film, that is, the layer of thin film surface oxide is placed). Regarding the purpose of the present invention, its effect is achieved especially when using metal flakes having high corrosion resistance, until the surface is substantially free from oxidation; therefore, their use is preferred.

For example, substrates with high corrosion resistance, such as aluminum flakes, which are available on the market in the form of a suspension in an organic solvent, and raw, and those substrates that have been processed by various means of surface preparation and were suspendirovanie in an organic solvent, are particularly recommended for use in the present invention.

When using such thin plates of metal substrates, which were previously subjected to anti-corrosion treatment (passivation), and these substrates alloy there is no need to perform processing based on the present invention simply to impart corrosion resistance; however, in addition to improved durability of the corrosion protection, corrosion-resistant layer according to the present invention other than the above-mentioned anticorrosive treatment is also effective for the formation of a smooth, uniform and dense layer of hydrated metal oxides after him.

Following the suspension get with a polar organic solvent, in which is dispersed specified such thin plates of metal substrates. According to the present invention, the suspension of the polar organic solvent is defined as a material that can be obtained in the following way:

(1) such thin plates of metal substrates, suspended in an organic solvent, suspended as they are in a polar organic solvent to obtain a suspension with the desired concentration;

(2) such thin plates of metal substrates in the form of solid particles (flakes partially dried so that was still some amount of solvent to prevent direct contact with air and humidity)in advance is obtained by separation by filtration and centrifugation organic solvent, and then suspended in a polar organic solvent to obtain a suspension with the desired concentration;

(3) if such thin plates of metal substrates were processed by means of surface preparation, the preparation tool surface is washed and removed, using a polar organic solvent, and after filtration of the substrates again suspended using a polar organic solvent to obtain a suspension with the desired concentration;

(4) if such a tone is their plates of metal substrates available on the market in powder form, which was subjected to a passivating treatment, suspended as they are in a polar organic solvent to obtain a suspension with the desired concentration.

Examples of polar organic solvents which are suitable for the present invention include ketones such as acetone, ethylmethylketone (MEK), methylisobutylketone (MIBK), and so on; alcohols with alkyl group which has 1-10 carbon atoms; tetrahydrofuran (THF), dimethylformamide (DMF); dimethyl sulfoxide (DMSO); dioxans; polyhydric alcohols and solvents cellosolve. Among these alcohols can be selected from those that are in a liquid state at normal temperature; examples of such alcohols include methanol, ethanol, isopropanol, butanol, Isobutanol, pentanol, hexanol, heptanol, octanol, isooctanol, nonanol, decanol and their isomers. Examples of preferred alcohols include ethanol, isopropanol, butanol, Isobutanol, because they are inexpensive and easy to handle at normal temperature. Especially isopropanol and ethanol, etc. are used because of their low volatility and low rates. In addition, these solutions can also be mixed. Further, if the metal alcoholate is used to form a layer of hydrated metal oxide (defined as "second stage - floor" in the present description), the present invention is used as the polar organic solvent alcohols, which have a high compatibility with the metal alcoholate. Naturally the appropriate selection should be made taking into account compatibility with the compounds of phosphoric acid and compounds of boric acid. From an economic point of view it is desirable to use the same polar organic solvent for processing compounds of phosphoric acid and/or compounds of boric acid (defined as "the first stage of processing "in the present description) and for the second stage reaction of the coating; however, it is also possible to use different solvents for the respective processing stages and coatings taking into account the reaction efficiency and compatibility with the reagents that are used at appropriate stages of the reaction. In addition, the polar organic solvent used for the removal of the means of surface treatment described in (3) above, respectively, chosen because of its compatibility with the tool surface treatment.

The suspension concentration of the polar solvent in which the suspended tonometrically-like metal substrates, can be suitably changed in accordance with the density of the used metal substrates, characteristic of the mixing device and the viscosity of the solvent.

Treatment of compounds of phosphoric acid and/or compounds of boric acid in the present invention corresponds to the pre-treatment for the formation of a layer of hydrated metal oxide, which is done simultaneously or sequentially; that is, by combining this treatment with the second stage of coating, and thus the purpose of the present invention.

In the present invention the first stage of processing or the second stage floor may not, individually, to lead to the achievement of the objectives of the present invention, that is, corrosion-resistant, homogeneous and dense layers of hydrated metal oxides obtained by the wet process, is presented below. In addition, even if the order is reversed, and the first stage processing is executed after the second stage coating, it is impossible to obtain an effect that exceeds the result obtained by only one second stage coverage.

Therefore, it is important that the layer of hydrated metal oxide formed on the surface treated with compounds of phosphoric acid and/or compounds of boric acid, and as soon as this structure is achieved, it is also possible to perform the first is Tadeu - processing and the second stage coating simultaneously or sequentially; however, it is preferable to first perform the first stage of processing, and then the second stage floor to guarantee the achievement of the specified structure.

Next will be described the first stage of processing.

The treatment of compounds of phosphoric acid and/or compounds of boric acid is accomplished by the addition of compounds of phosphoric acid and/or compounds of boric acid to the suspension polar organic solvent, in which were suspended such thin plates of metal substrates.

Given good anti-corrosion property, dispersibility and economic factors, the applied amount of the compounds of phosphoric acid and/or compounds of boric acid is preferably a number that corresponds to 0.0001-0.1 g as P2O3and/or In2About3per unit surface area (m2) similar to the thin plates of metal substrates, even more preferably is a number that corresponds is 0.0002-0.08 g and most preferably is a number that corresponds of 0.0005 to 0.05, So the amount used for such processing, usually defined on the basis of unit surface area of such thin metal plates of the subst is the ATA; that is, use a small amount, when the particle diameter is large, and use a large number, when the particle diameter is small.

When using compounds of phosphoric acid and compounds of boric acid in aqueous solution, it is desirable to determine the amount of water so that it does not become excessive when the number that is used (consumed) in sequential processes, and so did not increase the surface roughness of raw materials such thin plates of metal substrates. Further, it is also possible to use the solvents compounds of phosphoric acid and compounds of boric acid with water, which was mentioned above, a solvent together as a single solvent with a polar organic solvents, which are then used to produce suspensions of such thin plates of metal substrates. In any case, used polar organic solvent, respectively, chosen because of its affinity and compatibility of such thin plates of metal substrates with compounds of phosphoric acid and compounds of boric acid.

The terms "acid" and "acid" in the above compounds of phosphoric acid imply that the compounds of phosphoric acid has at least one Oh group. Next, choosing the appropriate organic ester group as the group associated with the compounds of phosphoric acid, the can is about to increase the affinity with a polar organic solvent, which is used in subsequent reactions.

After processing is completed, the suspension can be used as it is or in the form of solid particles, which can be obtained by filtering, for carrying out subsequent to the second stage reaction of the coating.

Next will be described the second stage is the reaction of the coating.

Taking into account that the metal substrate is preferably subjected to coating hydrates of metal oxides by the Sol-gel method; in addition, the preferred method that uses a metal alcoholate as the compound of the metal, which is necessary to hydrolyze.

The suspension obtained in the first stage reaction processing, can be used as it is, or firm h is sticky, obtained by filtration, can be again dispergirovany in a polar organic solvent, which may be identical or different from the solvent of the first stage reaction process for the preparation of suspensions. The second stage is the floor, requiring the presence of a catalyst, is carried out by addition of a metal link and a predetermined quantity of water necessary for hydrolysis. For hydrolysis can be used an acid catalyst; however, in order to form a uniform and dense coating layer, it is preferable to use ammonium compounds and/or amino compounds. The basic catalyst is characteristic for the present invention.

These hydrated metal oxides may be oxides of one type of metal or a complex oxide of two or more types of metals; however, given the high transparency, low refractive index and low cost of raw materials, hydrates of silicon oxides are particularly preferred.

In addition, it is also possible to form laminated layers of hydrated metal oxides including one or more kinds of these hydrated metal oxides. Examples of raw materials used at this stage include the alcoholate metals and salts of organic acids.

Any of the following approaches may be acceptable to add water in the Sol-gel method:

(1) adding a quantity of water necessary for hydrolysis, the suspension obtained in the first stage reaction processing before adding a solution of the metal alcoholate,

(2) adding water and metal alcoholate separately and at the same time to the suspension obtained in the first stage reaction processing, and

(3) adding metal alcoholate to the suspension obtained in the first stage reaction processing before adding water.

Similarly, the term "hydrated metal oxides", as it is used in the present description, including the claims, denotes a compound obtained by drying and, if desired, calcination hydrolyzed metal salts and metal joints, such as a metal alcoholate, etc. and compounds in which the metal oxides, hydrates of metal oxides and metal associated hydroxyl group, and other related conditions present as a single unit.

Vysokodekorativnye metal pigments, such thin plates, the present invention is mainly used as pigments having metallic luster, especially with glitter paint, printing ink, plastics, etc. as they can be used in the aqueous system or powder system, they are especially preferable from an environmental point of view and to improve the working environment, as a coating of powdered material and water-soluble paints, and printing inks. These vysokodekorativnye metallicheskie pigments, such thin plates, depending on their intended use can be used to perform, for example, processing for receiving light fastness, water resistance and resistance to weathering, required for use as automotive paints (for example, according to JP (A) Sho. 63-130673, JP (A) Hei. 1-292067, etc), for example, processing for obtaining the properties of the strong orientation of the plane (peeling), coloring and print areas (for example, according to JP (A) 2001-106937, Japanese Patent Application Hei. 11-347084, etc), processing water-based paints to water-based paints or printing ink (for example, according to JP (A) 8-283604, etc), silicon processing for improved dispersion and hydrogenperoxide processing to improve hydrophobic and lipophobic properties for use in cosmetics, surface preparation to prevent line melting, when used as a polymer (for example, according to JP (A) Hei. 3-100068), and different treatments to improve the dispersibility.

Vysokodekorativnye metal pigments, such thin plates, in the present invention are important and necessary as the basis for new interference colored pigments having metallic luster according to the present invention, described the lower is; and two stages of processing described above is carried out not just to give vysokodekorativnye surface properties of such thin plates of metal substrates, they are also important to obtain a dense and uniform layer of hydrated metal oxide, which is subsequently formed on the upper layer.

That is, only by forming vysokointensivnogo layer obtained by the treatment described above, it is possible to follow the method of coating hydrated metal oxides, the method of wet process and easily covered by hydrated metal oxide top layer anti-corrosion layer.

The following describes the interference colored pigments having metallic luster (claims 16-21) according to the present invention, on the basis of vysokodekorativnyh metal pigments, such thin plates according to the present invention, and which received further secondary coating of hydrated metal oxides comprising one or more layers. In the present invention, a secondary coating of hydrated metal oxide on the surface of the corrosion-resistant metals, such thin plates, may also be formed by a vapor-phase method (chemical deposition from the vapor the phase (CVD) and physical vapor deposition (PVD)), as well as the Sol-gel method; however, it is preferable to use the wet process method, which unlike vapor and Sol-gel methods, has no restrictions in respect of raw materials and production facilities and which is easy to operate method with a wide range of applications.

The main feature of the present invention is that at this stage because of the excellent anti-corrosion properties can be used the so-called wet process.

The metals constituting the secondary coating of hydrated metal oxides in order to generate the interference colors include titanium, aluminum, zirconium, tin, zinc, iron, chromium and cobalt, but also include silicon, boron, etc. Hydrated oxides of metals such as titanium, zirconium, tin, zinc, silicon, boron, etc. with transparency, and hydrated oxides of metals such as iron, chromium, cobalt, etc. with color transparency suitably selected for use. Among them, titanium is preferred, taking into account its high refractive index, and iron is preferable, taking into account the interference color having its own color.

The interference colored pigments having metallic luster according to the present invention can be is obtained from water-soluble metal salts using the Sol-gel method alone or in combination (for example, as a hydrated oxide alloy), multilayer coating, which is characterized by the fact that the material for each layer change (for example, in order: hydrated titanium oxide is hydrated iron oxides, and so on), or in multi-layer coating, which is characterized by the fact that the layers of hydrated metal oxide with a high refractive index (representative of this type - for example, hydrated titanium oxides, hydrated oxides of zirconium, etc.) alternate with layers of hydrated metal oxide of low refractive index (e.g., hydrated aluminum oxide, hydrated silicon oxides, hydrated oxides of boron, etc.)and so on

Determination of the wet process method, as it is used in the present invention, cited above, a more accurate method comprises, in an aqueous system,

(1) In the case of hydrolysis, neutralization, selecting the desired water-soluble metal salt (e.g., nitrate salt, sulfate salt, chloride, acetate salt etc) and a predetermined specified amount of an aqueous solution separately prepared alkaline solution, they feed in small portions (added dropwise) to a suspension vysokodekorativnyh metal pigments, such thin plates, which is obtained in advance, while maintaining a predetermined pH, Faure, the financing hydrolyzed layer and then rinse filtration, drying and, if necessary, firing;

(2) In the case of a thermal hydrolysis, adding a predefined number of desirable water-soluble metal salt to the suspension vysokodekorativnyh metal pigments, such thin plates, which is obtained in advance, and heating, the formation of the hydrolyzed layer and then washing, filtering, drying and, if necessary, firing.

In addition, you can also mention, as a variation of the method by hydrolysis neutralization (1), the method using instead of the aqueous solution of alkali ndimethylacetamide and urea, which lead to the alkaline solution, when heated (the so-called "homogeneous deposition method"). Thus, the interference colored pigments having metallic luster, which are the subject of the present invention can be obtained by arbitrarily selecting the water-soluble metal salts, their use separately or in combination and change the time during which they are introduced into the suspension.

More specifically, the interference colored pigments metal layer having metallic luster according to the present invention can be obtained in the case of coatings of the same hydrated metal oxide choosing one water-soluble metal salt, is such as titanium, zirconium, tin, zinc, iron, chromium, cobalt, etc. to cover gidratirovannym a metal oxide by hydrolysis neutralization under alkaline conditions or by thermal hydrolysis; in the case of coating with a mixture of metals by mixing a variety of metal salts for the application of hydrated oxides of a mixture of metals by neutralization or hydrolysis thermal hydrolysis; or in the case of multilayer coatings by sequentially adding various metal salts in order to apply successive layers of hydrated metal oxide; and thereafter washing, filtering, drying and, if necessary, firing. When forming according to the present invention a multilayer coating with alternating layers of aqueous solutions of metal salts, forming layers of relatively high refractive indices (mentioned earlier) and layers with a low refractive index (mentioned earlier), alternately add small portions (added dropwise), in the same manner, to the base, i.e. suspension vysokodekorativnyh metal pigments, such thin plates, consistently covering their hydrolate. Colour intensity of the interference colored pigments having metallic luster obtained by forming alternating layers of the multilayer coating, luchshe the camping due to the accumulation of interference, when the reflection/transmission of light at the boundary of each layer is repeated alternating coating of multiple layers, alternately control the optical thickness (for detailed review see WO 98/53011). The color saturation, the interference colored pigments having metallic luster obtained by forming alternating layers of the multilayer coating has a high saturation, which cannot be obtained by a single coating, gidratirovannym a metal oxide with a high refractive index, using a single metal.

In the present invention, if the hydrated titanium oxide included in the constituent elements of the interference of the color layer, it is possible to change them on the rutile-model, using the compound of tin or other means of rutile, to increase the refractive index of the hydrated crystals of titanium oxide. Coloring properties improve by changing the rutile-type titanium oxide.

The interference colored pigments having metallic luster according to the present invention, produce the so-called effect of the color transition (characterized by the change in the observed color change of angle), combining the inherent color of the metal (Maston) and the interference color as corrosion SL is th is uniform and dense, and hydrated metal oxides with high refractive index deposited on its surface, have a high homogeneity and density.

These interference colored layers may be made known colored or black inorganic and organic pigments ultra fine particles to obtain the interference colored pigments having metallic luster, while retaining its color (masstone) of these pigments in the generation of interference colors. This is made possible only by the light fixture in the service of the wet process method, which allows to extend these pigments in different color amplitude and expand the scope of their application.

By conducting various types of additional processing surface of the interference colored pigments metal layer having metallic luster obtained according to the present invention meet the requirements to quality for the uses for which these treatments are used. For example, it is possible to perform processing for receiving light fastness, water resistance and resistance to weathering, required for use as automotive paints (for example, according to JP (A) Sho. 63-130673, JP (A) Hei. 1-292067, etc), for example, processing for obtaining the properties of strong Orient the AI plane (peeling), necessary in painting and print areas (for example, according to JP (A) 2001-106937, Japanese Patent Application Hei. 11-347084, etc), processing water-based paints to water-based paints or printing ink (for example, according to JP (A) 8-283604, etc), silicon processing for improved dispersion and hydrogenperoxide processing to improve hydrophobic and lipophobic properties for use in cosmetics, surface preparation to prevent line melting, when used as a polymer (for example, according to JP (A) Hei. 3-100068), and various treatments to improve the dispersibility.
