Title:
ACTINIC-RAY-CURABLE INK COMPOSITION AND METHOD FOR PRODUCING PRINTED MATTER
Document Type and Number:
WIPO Patent Application WO/2022/255110
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an actinic-ray-curable ink composition that gives printed matter which has low-temperature flexibility (elongation resistance) while retaining room-temperature blocking resistance and which is excellent in terms of flexibility and stacking durability. The actinic-ray-curable ink composition comprises a monomer A represented by general formula (1), the amount of which is 35-50 mass% with respect to the whole composition, a monomer B having a structure represented by general formula (2) and a polymerizable unsaturated double bond, and at least one polyfunctional polymerizable compound selected from among urethane (meth)acrylates and amino(meth)acrylates.
