WIPO Patent Application WO/2019/117231
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a flexographic printing ink composition which uses a large amount of carbon-neutral raw materials, wherein the flexographic printing ink composition is used for paper containers and has excellent physical properties such as coating properties, re-solubility, condensation resistance, and hexane resistance, or is used for thin paper used for food packaging and has excellent physical properties such as water and abrasion resistance, heat resistance, coating properties such as oil and friction resistance, and re-solubility. In order to resolve the problem, an aqueous flexographic printing ink composition containing: a pigment; a pigment dispersion resin; a rosin-based resin emulsion having an acid value of 80-350 mgKOH/g and/or a neutralized product of a volatile basic compound and a rosin-based resin having an acid vale of 80-350 mgKOH/g; a styrene-acrylic resin emulsion having a glass transition temperature of -30°C to 60°C and an acid value of 30-80 mgKOH/g; and a water-containing solvent is provided.
