ACTIVE ENERGY RAY-CURABLE INK COMPOSITION, LAYERED BODY USING SAID INK COMPOSITION, IMAGE FORMING METHOD FOR FORMING IMAGE ON SUBSTRATE, AND METHOD FOR PRODUCING PRINTED ARTICLE

WIPO Patent Application WO/2018/235748

A1

Provided is an active energy ray-curable ink composition which exhibits excellent adhesion to a substrate, even when the active energy ray-curable ink composition is coated onto the surface of a substrate which primarily exhibits a wetting tension no greater than a prescribed value. As active energy ray-polymerizable components, the active energy ray-curable ink composition at least contains the component A and the component B from among: a component A which is a bifunctional component represented by general formula (1) R4-CH=CR1-COOR2-O-CH=CH-R3 (In the formula, R1 represents a hydrogen atom or a methyl group, R2 represents a divalent organic residue having a carbon number of 2-20, inclusive, R3 represents a hydrogen atom or a monovalent organic residue having a carbon number of 1-11, inclusive, and R4 represents a hydrogen atom or an alkyl group having a carbon number of 1-4, inclusive); a component B which is a urethane(meth)acrylate component having a structure derived from an alkanediol; a component C which is a bifunctional component that does not contain the component A or the component B; and a component D which is a monofunctional component that does not contain the component B.
