Holographic transfer single coating material and its preparation method

Abstract

The invention relates to a coating material of the holographic anti-counterfeiting printing industry, particularly to a holographic transfer single coating material and its preparation method. The holographic transfer single coating material composition provided in the invention can improve the adhesion force and is suitable for post-printing, and consists of the following components by mass: 8-20 parts of thermoplastic acrylic resin, 2-7 parts of cellulose ester, 1-6 parts of vinyl chloride-vinyl acetate resin, 75-85 parts of solvents, 0.5-1.0 part of auxiliary agents, and 1.5-4.5 parts of a functional additive. The coating material needs only one time coating, and has the characteristics of high production efficiency, energy saving and emission reduction; the obtained holographic pattern is clear, and the anti-counterfeiting effect is strong; an aluminized back adhesive can transfer completely, the transfer paper has good smoothness and high folding endurance, an aluminum layer and an information layer, as well as the information layer and a paper substrate both have strong adhesion; the coating material has good post-printing adaptability, and printing can be carried out directly after transfer and curing, the printing ink can have good leveling property, and the quality defects such as color difference, lifting, color rupture, reverse pull and the like do not exist.

[0002] China's cigarette pack printing industry has the characteristics of high technical content and complicated process. The packaging of gold and silver cardboard can endow products with high-end, exquisite and anti-counterfeiting characteristics. The gold and silver cardboard has been developed from the composite method to the transfer method; the transfer method is to apply the transfer coating on the polyester film, after molding, aluminizing, and then coating the composite glue, so that the aluminized film and paper are combined, and then the The film is peeled off to become an aluminum-coated transfer wrapping paper with a holographic laser pattern; after the holographic transfer coating is transferred, it needs to have good adhesion and printing adaptability, and its adhesion includes the information layer between the coating itself and the aluminum layer, that is, the information layer. It refers to the adhesion between the coating material coated on the PET film, the semi-finished product with the anti-counterfeiting information pattern after molding, the paper and the transfer layer including the information layer and the aluminum layer, and the transfer coating material and printing ink , printing also needs to be suitable for special printing such as post-printing, offset printing, and more high-end UV printing; the existing transfer coatings cannot be molded or the molding performance is unstable, such as double-plate seamless molded easy-to-stick plates, sometimes need to coat two Layer, that is, a release layer needs to be coated before removing the coating material. The aluminum adhesion is not strong, the paper is not firmly bonded, the ink leveling is poor during printing, the bottom is biting and the color is bursting, which makes the product quality unstable. In severe cases, the scrap rate is high, which affects the production and development of holographic transfer and its coatings. How to make the coating materials meet the production process requirements, and how to solve the influence of adhesion on the process parameters of subsequent processes, that is, to provide a kind of coating with excellent adhesion. A single-coat holographic aluminum-plated transfer coating material composition suitable for post-printing to solve the defects in the current production technology is an urgent problem for engineers and technicians
