Problems solved by technology

[0006] However, the currently commonly used coating paste for sublimation transfer printing is not widely applicable, for example, it can only be applied to textiles or ceramic products, etc., and the pattern texture after transfer is not very clear, and the color fastness is not very high , the gloss is not good enough to fully meet people's increasingly higher requirements for transfer printing effects

Abstract

The invention discloses thermal sublimation transferring-printing coating pulp which comprises the following components in percentage by mass: 35-55% of hydroxyl-terminated polyester modified crylic acid resin, 10-30% of methyl etherified urea resin or butyl etherified urea resin, 0.1-1% of acrylic leveling agent and 24.5-45% of diluent, wherein the solid content of the hydroxyl-terminated polyester modified crylic acid resin is 60%+/-2%, and the acid value is 3-5mgKOH/g; the solid content of methyl etherified urea resin or butyl etherified urea resin is 75%+/-2%, the acid value is less than 1mgKOH/g; the diluent is a mixture of n-butyl acetate and diacetone alcohol. When the coating pulp is coated on the surface of a printed article and is heated, the hydroxyl-terminated polyester modified crylic acid resin has cross-linking reaction with methyl etherified urea resin or butyl etherified urea resin to form a net-shaped structure, and thus the pattern generated after transferring-printing is clear, full, high in color fastness, long-lasting without fading, and high in glossiness.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer printing, and more specifically, the invention relates to a coating slurry for thermal sublimation transfer printing and a method for performing thermal sublimation transfer using the coating slurry. Background technique [0002] In recent years, in order to solve the problem that the surface decoration of glass, ceramics, metal and other products is too simple, people have begun to apply thermal transfer technology, and use the method of direct transfer to decorate the products of the above materials. However, due to the products of the above materials The surface is smooth and polar, and the adhesive layer of the general transfer film cannot be tightly combined with the surface of the above-mentioned products. Therefore, the graphics and texts are very easy to fall off after the transfer, and the decorative effect is not ideal. For this reason, ZL200710033041 discloses an adhesive to ma...
