Laser information coating for gold stamping

Abstract

The invention provides a laser information coating for gold stamping, which comprises the following raw material components in percentage by weight: 40 to 50 percent of maleic acid resin, 20 to 30 percent of malamine resin, 5 to 15 percent of butanone, 1 to 5 percent of normal butanol, 1 to 5 percent of dimethylbenzene, 1 to 5 percent of ethylene glycol monobutyl ether acetate and 1 to 2 percent of paratoluenesulfonic acid. The laser information coating for gold stamping solves the problems that thermoplastic acryl series general gold stamping laser information coatings generally used on the market at present have lower temperature resistance and poor solvent resistance, and greatly reduces the loss caused by the shortages of temperature resistance and solvent resistance during the use of customers; and the product has the advantages of high brightness, good toughness, difficult breakage, strong repairability, environment-friendly materials, low cost, simple process and the like, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a Radiation Information Coating Paint. Background technique [0002] In the packaging and printing industry, bronzing laser printing has become a trend in commodity packaging printing, which can bring luxury, noble and exquisite feelings to commodities, so the application of bronzing can be seen on many high-end commodities and printed materials, such as cosmetic packaging , Wine boxes, wine labels, cigarette packs, catalogues, calendars, advanced pens, stationery, etc. [0003] The effect of bronzing laser printing depends to a certain extent on the quality of the laser information coating. At present, the thermoplastic acrylic series of laser information coating coatings for bronzing are commonly used in the market. Although the acrylic layer has the advantages of high brightness, good toughness, unbreakable, and strong repairability, the layer has low temperature resistance. , The ...

AI Technical Summary

Problems solved by technology

At present, the thermoplastic acrylic series of laser information coating coatings for bronzing are commonly used in the market. Although the acrylic layer has the advantages of high brightness, good toughness, unbreakable, and strong repairability, the layer has low temperature resistance. , the problem of poor solvent resistance, there are great limitations in the selection of hot stamping substrates and the improvement of hot stamping speed

At the same time, due to the difficulty and high cost of acrylic production, the cost of coating is too high

[0004] Chinese patent application number: 200810029355.8 discloses a laser transfer coating and its preparation method, mainly composed of methyl methacrylate, butyl methacrylate, acrylic acid, vinyl acetate, ethyl acetate, propylene glycol monomethyl ether, n-butyl acetate Ester, benzoyl peroxide and nitrocellulose are heated to prepare a laser transfer coating, but the coating still has the problems of low temperature resistance and poor solvent resistance after coating

[0005] Chinese patent application number: 200510031854.7 discloses an environment-friendly laser transfer composite aluminum foil paper and its preparation process, the coating is made of water-soluble amino resin or water-soluble polyurethane resin or water-soluble alkyd resin or water-soluble acrylic resin or cellulose resin , plus additives, pigments, co-solvents, water, or any combination thereof, the water-based laser transfer coating is prepared by synthesis, wetting and dispersing, but the performance of high temperature resistance and solvent resistance is still not ideal
