Problems solved by technology

The pearlescent effect is often achieved by applying electronic ink varnish on the pearlescent varnish layer. Not only is the process complicated, but the adhesion between the pearlescent varnish layer and the electronic ink layer is not enough.
These problems have restricted the development of personalized electronic ink printing industry

Abstract

The invention provides an electronic ink printing coating compound with a pearl effect and a preparation method of the compound. The compound comprises cation acrylic emulsion, ethylene-vinyl acetate copolymer emulsion, pearl pigments, solvents and auxiliaries. The preparation method includes the steps: uniformly mixing the cation acrylic emulsion with the ethylene-vinyl acetate copolymer emulsion and then adding the solvents; uniformly mixing the emulsion with the solvents, adding the auxiliaries, uniformly mixing the emulsion, the solvents and the auxiliaries and then adding the pearl pigments to obtain the electronic ink printing coating compound with the pearl effect. Compared with the prior art, the compound has the advantages that the compound is a waterborne coating, conforms to the trend of environmental protection and adapts to various substrates such as paper, aluminum foils, aluminum-plating paper, PET (polyethylene terephthalate) films and OPP (oriented polypropylene) films, the production process of pearl printing paper is simplified, and the problem of poor fastness of electronic ink varnish and pearl varnish layers is solved.

Description

technical field [0001] The invention relates to an electronic ink printing coating composition with a pearlescent effect and a preparation method thereof, belonging to the technical field of electronic ink coatings. Background technique [0002] With the vigorous development of online e-commerce, personalized custom printing is becoming more and more popular. Compared with traditional printing methods, digital printing eliminates the cumbersome plate-making process, and has no limit to the "printing volume", which is more in line with the development trend of personalized customization. Among them, the electronic ink printing technology has the advantages of high image edge sharpness, high resolution, no color difference, wide color gamut, instant drying, etc., and is welcomed by the majority of printing manufacturers. As the printing medium of electronic ink, the technical barrier of electronic ink printing varnish is high. At present, only a few companies in Japan, Europe...
