Problems solved by technology

[0004] The monomers and resins synthesized by the emulsion have poor hydrophilicity, so the viscosity of the synthesized water-based coating is low, and it is difficult to coat. It is difficult to meet the high-speed coating process requirements of the existing coating machine. It is often necessary to add additional leveling aids (mostly surfactants) to increase the viscosity of the water-based coating to achieve a good coating effect
However, in the vacuum aluminum plating process of the laser transfer printing operation, the added leveling agent will erode the aluminum layer and cause the aluminum layer to lose its metallic luster, which will affect the effect of aluminum plating; The influence of external leveling aids reduces the bonding strength, so the application of external leveling aids on laser transfer foil information layer coatings is greatly limited, so no additional leveling aids are added, but the formulation of the coating is changed. Become the key breakthrough to increase the viscosity of water-based coatings

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based laser information layer coating and a manufacturing method thereof. Background technique [0002] Most of the information layer coatings in the core part of laser transfer foil are solvent-based. The synthesis process of solvent-based coatings is simpler, easier to operate, and better in coating performance than water-based coatings, but its defects are also obvious, not only production waste, cost High and there are many limitations in application, for example, some food packaging and cigarette packaging strictly control the VOC (volatile organic compound) content of their printed matter, and it is difficult for solvent-based coatings to meet the volatile organic compounds. Therefore, water-based coatings are used in laser transfer. The application of information layer coating in the core part of printed foil is more and more extensive. [0003] Water-based coati...
