The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates to a printing ink composition for a seamless banks, which has excellent suitability for printing, such as portability and stability on the machine, and has excellent compatibility with the coating varnish, and provides good characteristics of a coating film, and to a method of coating a seamless Bank using the ink composition.

The LEVEL of TECHNOLOGY

Seamless cans are widely used as packaging for beverages based on fruit juices, soft drinks, carbonated beverages, alcoholic beverages such as beer, and food. The outer surface of the seamless metal cans that are molded in the form of a cylinder, propective or cover for decorative purposes to increase the attractiveness of the product and prevent corrosion.

There is a situation where the application of the coating lacquer "raw" is carried out after the surface of the seamless cans for decorative purposes applied silver finish or white finish. Therefore, the paints used for seamless banks must show adhesion to various substrates.

As for the ubiquitous seamless cans, then use wax when vyshtampovannye metal bases the first material, such as aluminum sheet or steel sheet, for forming the banks and putting it deep drawing with thinning to give her body a cylindrical shape. Therefore, after molding stage requires washing, and use large amounts of water.

In recent years there has been developed a seamless Bank by using a sheet covered with a complex polyester obtained by layering a complex polyester on a steel sheet or aluminum sheet, as the Bank, which does not require a stage of washing for the protection of the environment, and were developed printing methods and coating for such new seamless cans.

However, especially in the printing and coating, where for seamless banks, made using the coated complex polyester sheet, apply top coat lacquer, water-based, difficult to achieve a combination of good suitability for printing or coating with good properties of a coating film in the case of the application of commonly used inks for printing on metal, including the modified aliphatic acid complex polyester.

Namely, in the system of printing and coating for seamless banks, where as a metal base material used sheet with Konoplianik coating, this situation occurs, what happens to Galatia paint in stages and coating of lacquer method "raw" after the printing process and hot drying it, thereby making the concentration uneven.

As for inks for printing on metal, showing compatibility with aqueous coating varnish application examples of the diluent component for compatibility with the aqueous coating varnish described, for example, in patent documents 1, 2, 3, 4, 5 and 6.

However, in these examples, the wetting ability with respect to coating the water-based lacquer obtained by the use of a diluent as a component having the features of high hydrophilicity, but the paint using a dilution component generates a large number of colorful mist during printing, thereby causing pollution stamped and provided with a coating banks and worsening working conditions in the workplace.

Examples achieve compatibility with water varnish by applying the polymer component is described, for example, in patent documents 7 and 8.

In patent document 7 give compatibility with aqueous coating varnish and prevent the formation of colorful mist the introduction of a monohydroxy alcohol having from 6 to 26 carbon atoms, in cooperation with the anhydride of the polycarboxylic acid, and then conduct additional interaction with a polyhydric alcohol, thereby leaving numerous hydroxyl groups.

In patent document 8 is idut compatibility with aqueous coating varnish and prevent the formation of colorful mist by applying a monobasic saturated carboxylic acids branched type, a polyhydric alcohol and polycarboxylic acid, thereby introducing many free hydroxyl groups. In this way improve the wetting ability in relation to the water surface varnish, but the dispersed state of the pigment in the paint cannot be stabilized sufficiently, and coagulation takes place depending on conditions of use.

The BEST OPTION of carrying out the INVENTION

Modified aliphatic acid complex of the polyester (A) with attached polybasic acid used in the present invention can be obtained, for example, by the following method.

First, a modified aliphatic acid complex of the polyester (B), obtained using aliphatic acids or vegetable oils as a source of substances known to synthesize aliphatic acid method or way of interesterification. Reaction accession internal anhydride of the polybasic acid to the terminal hydroxyl group of this original modified the CSOs aliphatic acid complex of the polyester (B) introducing a carboxyl group into the tail fragment of a modified aliphatic acid complex of the polyester to obtain a modified aliphatic acid a complex of the polyester (A) with attached polybasic acid.

Next, the original modified aliphatic acid complex of the polyester (b) and a modified aliphatic acid complex of the polyester (A) with attached polybasic acid explained in more detail below.

Original modified aliphatic acid complex of the polyester (B) can be obtained, for example, by the reaction of a polyhydric alcohol, polybasic acid and aliphatic acid. In addition, the original modified aliphatic acid complex of the polyester (B) can be obtained by introduction of ester of aliphatic acid in the interesterification reaction with a complex of the polyester obtained by the reaction of a polyhydric alcohol with a polybasic acid.

Examples of applicable polyhydric alcohol are diatomic alcohols, such as ethylene glycol, diethylene glycol, triethylene glycol, 1,6-hexanediol, bisphenol a and hydrogenated bisphenol a; trivalent alcohols such as glycerin, trimethylated and trimethylolpropane; and alcohols with four or more hydroxyl groups such as pentaerythritol and dipentaerythritol.

Examples of polybasic acids that can be used to obtain the source of the modified aliphatic acid complex of the polyester (B)are dibasic acids, that is their as phthalic anhydride, isophthalic acid, terephthalic acid, succinic anhydride, adipic acid, tetrahydrophthalic anhydride, hexahydrophthalic anhydride and maleic anhydride; and trekhosnovnye acid, such as trimellitic anhydride and anhydride methylcyclohexanecarboxylic acid.

Examples of aliphatic acids for modification are natural and synthetic aliphatic acid, such as capric acid, lauric acid, myristic acid, Caprylic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, ricinoleic acid, linolenic acid and aleocharinae acid; and vegetable oils such as soybean oil, castor oil, coconut oil, linseed oil, safflower oil, digidratirovannogo castor oil, tall oil and rice oil. These aliphatic acids may be used individually and can be used in combination of two or more of them. In addition, the combination can be used monobasic acid other than the above-mentioned aliphatic acid, for example, benzoic acid, para-tert-butylbenzoic acid and abietic acid.

Aliphatic acids are added in an amount such that the degree of modification of aliphatic acids in modificirovana the aliphatic acid complex of the polyester (A) with attached polybasic acid ranged from 35 to 65% by weight, preferably from 40 to 60 mass%.

When the degree of modification of aliphatic acids is less than 35% by weight, portability and stability on the machine received the ink composition is reduced. When the degree of modification exceeds 65% by weight, in view of the deterioration of mechanical characteristics such as hardness of a coating film of the ink composition, it is necessary to admix other additives such as a hardener, in particular, polyamines hardener.

Upon receipt of the original modified aliphatic acid complex of the polyester (C) the esterification is conducted so that the total equivalent amount of hydroxyl groups of a polyhydric alcohol is used in excess relative to the total acid equivalent (generic equivalent of carboxyl groups) monobasic acids, including the aforementioned aliphatic acid and a polybasic acid.

Polyhydric alcohol, polybasic acid and aliphatic acid are mixed in such quantities as to obtain the original modified aliphatic acid complex of the polyester (B) with a hydroxyl number of from 70 to 250 mg KOH/g, and the mass-average molecular weight converted based on styrene, from 3000 to 30000.

When the hydroxyl number of the original modified aliphatic acid complex of the polyester (B) extending t is more than 250 mg KOH/g, as the number of hydroxyl groups in the modified aliphatic acid complex of the polyester (A) with attached polybasic acid becomes too large, reduced adhesion to the sheet with Konoplianik coating. When the hydroxyl number of the original modified aliphatic acid complex of the polyester (b) is less than 70 mg KOH/g, wetting ability relative to the water surface varnish insufficient, and there is coagulation of ink, when the aqueous overcoat varnish is applied by the method of "raw".

The mass-average molecular weight converted based on the styrene is preferably from 3,000 to 30,000, more preferably from 6000 to 16000. When the molecular weight is too low, the target driving forces coagulation modified aliphatic acid complex of the polyester (A) with attached polybasic acid is too weak, and the durability of a paint coating film becomes insufficient. On the other hand, when the molecular weight is too large, the viscosity of the modified aliphatic acid complex of the polyester (A) with attached polybasic acid becomes too high, and the ink cannot be obtained in the specified form.

In this esterification, as the number of hydroxyl groups (a polyhydric alcohol) is large, to the PCI-e slot the number of received source modified aliphatic acid complex of the polyester (B) is so small, that is less than 10 mg KOH/g When this modified aliphatic acid complex of the polyester (B)having an acid number of less than 10 mg KOH/g, is used as such for the ink composition, even if the hydroxyl number is from 70 to 250 mg KOH/g, and the mass-average molecular weight converted based on the styrene is from 3000 to 30000, wetting ability in relation to the water surface varnish is good, but the stability of the dispersion of the pigment is insufficient, and the purpose of the present invention cannot be achieved.

On the other hand, in the case of obtaining the source of the modified aliphatic acid complex of the polyester (C) in conditions of excess acid (polybasic acid and aliphatic acid) acid number increases, but the hydroxyl number is less than the above range, and even if to ensure interoperability polybasic acid with a complex polyester in the subsequent stage, a modified aliphatic acid complex of the polyester (A) with attached polybasic acid having a hydroxyl target number cannot be obtained.

Further, there may be an intention to stop the esterification during the reaction to control acid number, but in reality it is difficult to control the reaction for the regulation of the acid is about numbers and hydroxyl numbers.

Modified aliphatic acid complex of the polyester (A) with attached polybasic acid can be obtained by the reaction of accession internal anhydride of the polybasic acid to the terminal hydroxyl groups of the above-mentioned original modified aliphatic acid complex of the polyester (B).

In case of use of the polybasic acid (acids, all carboxyl groups which are free of carboxyl group), not having in their molecule fragment acid anhydride, interacting as a polybasic acid, the interaction with the terminal hydroxyl groups of the original modified aliphatic acid complex of the polyester (B) is not a reaction of the accession and esterification, followed by dehydration, and thereby the connection of the end hydroxyl groups of the original modified aliphatic acid complex of the polyester (b) with a polybasic acid, which is the result of a sharp increase in molecular weight and complicates the introduction of carboxyl groups. Therefore, the use of such polybasic acid is impractical. On the contrary, it is preferable to use for the reaction of polybasic acid having in its molecule fragment anhydride acid because the reaction starts at a lower temperature, and the resulting reaction of the joining terminal hydroxyl groups of the original modified aliphatic acid complex of the polyester (B), and carboxyl groups can be easily introduced, whereas the molecular weight does not increase.

Examples of applicable internal anhydride of the polybasic acids are the anhydrides of dibasic acids, such as phthalic anhydride, succinic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride and maleic anhydride; anhydrides trekhosnovnykh acids, such as trimellitic anhydride and anhydride methylcyclohexanecarboxylic acid. When joining these acid anhydrides acid number and hydroxyl number, in particular the acid number can be adjusted, while the mass-average molecular mass does not change almost. Particularly preferred internal anhydrides of polybasic acids, for reasons of education colourful fog and good solubility in the polymer are trimellitic anhydride and phthalic anhydride.

It is preferable to conduct the reaction at a temperature of from 100 to 200°C. When the reaction temperature is below 100°C, there is a situation where the solubility of the internal anhydride of the polybasic acid in the original modified aliphatic acid complex of the polyester (B) is low, the reaction of the connection with the terminal hydroxyl groups of the original modified aliphatic acid complex polyester is (In) almost does not leak, and the internal anhydride of the polybasic acid is a solid.

When the reaction temperature exceeds 200°C, carboxyl groups formed by the reaction of accession internal anhydride of the polybasic acid and other carboxyl group contained in the internal anhydride trehosnovnoy or more acid, are subjected to esterification in interaction with the terminal hydroxyl groups of the original modified aliphatic acid complex of the polyester (B). Therefore, there is a situation where the acid number and hydroxyl number of the received modified aliphatic acid complex polyester with attached polybasic acid is reduced, and the target acid number and hydroxyl number cannot be obtained, and excessively increases the molecular weight, leading to gelatinising.

The hydroxyl number of the modified aliphatic acid complex of the polyester (A) with attached polybasic acid is 60 to 200 mg KOH/g, preferably from 80 to 180 mg KOH/g When the hydroxyl number exceeds 200 mg KOH/g, as the number of hydroxyl groups becomes too large, deteriorating the adhesion to the sheet with Konoplianik the floor, and, on the other hand, when the hydroxyl number is less than 60 mg KOH/g, wetting ability of the wearing water surface varnish becomes insufficient, and when applying water surface varnish "raw" is the coagulation of ink.

Acid number of the modified aliphatic acid complex of the polyester (A) with attached polybasic acid varies from 10 to 60 mg KOH/g, preferably from 15 to 40 mg KOH/g When the acid number is too small, the dispersion stability of the pigment becomes insufficient, and, in particular, when applying the aqueous coating varnish "raw", in some cases, there is the problem of coagulation of the pigment in the paint, depending on the type of varnish. When the acid number is too large, the polarity of the polymer becomes too high, resulting in reduced fluidity and transferability of paint.

The mass-average molecular weight converted based on styrene, of a modified aliphatic acid complex of the polyester (A) with attached polybasic acid is from 3000 to 30000, preferably from 6000 to 16000. When the molecular weight is too low, the driving force of coagulation modified aliphatic acid complex of the polyester (A) with attached polybasic acid is too small, and colorful coating film loses strength. On the other hand, when the molecular weight is too large, the viscosity of the modified aliphatic acid complex of the polyester (A) with Pris the United polybasic acid becomes too high, and the paint cannot be obtained in the specified form.

Modified aliphatic acid complex of the polyester (A) with attached polybasic acid according to the present invention can be formed in the printed colorful composition for seamless banks by mixing, for example, pigment and solvent as a component.

Printed colorful composition for seamless cans according to the present invention includes a modified aliphatic acid complex of the polyester (A) with attached polybasic acid and other components, for example, the pigment and the solvent as a component.

Common pigments used in inks for printing on the cans, can be applied without limitation to such an extent as they are heat resistant, fade resistant and resistant to treatment in the muffle. Examples thereof are inorganic pigments such as titanium oxide, silicon oxide and carbon black; and organic pigments such as phthalocyanine blue, copper, Watchung Red, chinagreen, diketopiperazines and chieftain.

The amount of pigment varies depending on its type and object, and can usually be selected within the range from 10 to 60% by mass in the ink composition.

Can be applied known dissolve and, used in inks for printing on the cans. Examples thereof are aliphatic hydrocarbon, alicyclic hydrocarbon, aromatic hydrocarbon, such as alkyl benzene, and higher alcohol, which have a boiling point of from about 230°to about 400°C.

In addition, the combination can be applied to other polymers commonly used in inks for printing on the cans. Examples of polymers that may be used in combination, are inden-coumarone resin, epoxy resin, polyketone, modified rosin primulina acid, polyamine, benzoguanamine resin that does not contain oils complex polyester and dispersion of a phenolic resin, rosin. In addition, as the case may be made of conventional additives such as lubricating agent, curing catalyst and a dispersant.

The viscosity of the ink composition according to the present invention can be optionally selected by adjusting the amount of solvent in accordance with the printing method. For example, for high offset printing rate stickiness (Japanese industrial standard JIS K-1) adjusted to a value of from 4 to 12, and the flow index (JIS K-1) regulate the level from 27 to 47. For waterless lithographic printing, it is preferable to adjust the viscosity to a value bolivianos, than for commonly used colors, and usually it is desirable that the stickiness indicator was adjusted to between 6 to 15, and the turnover of regulated at the level of from 25 to 45.

Colorful composition according to the present invention can be prepared in the usual way using a roller mill, ball crusher or ball mill.

Printed colorful composition for seamless cans according to the present invention can be used for conventional printing methods such as a method of dry offset printing, using embossed rubber plates and offset printing based waterless lithography. The thickness of the colorful coating film is not necessarily chosen within the range from 0.5 to 6 microns.

The present invention also relates to a method for coating a seamless Bank, including forming the metal substrate with the formation of banks by vyshtampovanny, applying a layer of ink on the surface of the banks with the use of the printing ink composition for a seamless cans according to the present invention, the coating of thermosetting coating of lacquer on the layer of printing ink and then carrying out processing for thermal curing.

Seamless Bank, covered with colorful composition according to the present invention, the submitted is a Bank, made by wystepowaniem metal substrate for forming the banks, and examples of the metal substrate is aluminum sheet, steel sheet and the sheets of aluminum and steel, laminated closepreview film, etc. in Addition, these sheets can be subjected to chemical conversion treatment, plating, processing in the sizing press, and applying a white and silver coating.

Thus obtained colorful composition may be printed above the traditional methods of printing on the outer surface of the seamless banks without any restrictions.

The effect of the present invention is manifested especially when colorful composition is applied to the sheets with Konoplianik coating as the metal substrate.

Then put thermosetting coating lacquer without hot drying printing ink layer, and, finally, carry out the curing by hot drying, thereby completing the printing process seamless Bank. The hot drying conditions are not specifically limited, and mostly preferably heated at a temperature of from 160 to 260°C over a period of time from 20 seconds to 10 minutes.
