ACTIVE ENERGY BEAM-CURABLE INK COMPOSITION, LAMINATE USING THIS INK COMPOSITION, AND IMAGE FORMING-METHOD OF FORMING AN IMAGE ON A SUBSTRATE

摘要

Provided is an ink composition that tracks a flexible substrate extremely well.　This active energy beam-curable ink composition contains, as active energy beam-polymerizable monomers, monomer A (a monofunctional monomer having a cyclic structure) and monomer B (a monomer having three or more functional groups, where the ratio of molecular weight/number of functional groups ≥ 200). The total content of monofunctional monomers including monomer A is at least 85.0mol%, and the content of monomer B is 0.5mol% to 10.0mol%.
