Problems solved by technology

[0002] Traditional solvent-based ink resins use benzene, ester, and ketone solvents as diluents. During production and use, all solvents are volatilized and released into the air, which will cause serious pollution to the atmospheric environment.

Abstract

The invention relates to general alcohol-soluble resin for color ink, which is characterized in that the resin is prepared from 3%-15% w / w of carboxylic polyester resin and 40%-80% w / w of vinyl acetate. The carboxylic polyester resin-modified vinyl acetate-acrylate copolymerized alcohol-soluble resin is applicable to waterborne intaglio ink, flexographic plate printing ink, paper printing and plastic film printing.

Description

technical field [0001] This patent relates to a preparation method of alcohol-soluble resin suitable for various color ink systems. Background technique [0002] Traditional solvent-based ink resins use benzene, ester, and ketone solvents as diluents. During production and use, all the solvents are volatilized and released into the air, which will cause serious pollution to the atmospheric environment. As the country pays more and more attention to environmental protection requirements, traditional solvent-based inks are gradually developing into environmentally friendly alcohol-soluble and water-soluble inks, especially suitable for gravure printing of plastic film packaging materials such as food and medicine. At present, most of the resins used by domestic manufacturers of alcohol-soluble ink are imported products, which are expensive and have no competitive advantage. Compared with this, the ink prepared by the alcohol-soluble resin provided by this patent is not only ch...
