Abstract
An object is to provide a photocurable inkjet printing ink composition offering curability and adhesion on printing targets including sheets whose printing face is constituted by paper, polyester, polyvinyl chloride, ethylene-vinyl acetate-based copolymer, or other vinyl-based polymers, etc., and additionally having storage stability. The cured coating film has low odor, low tackiness, abrasion resistance, high water resistance, high ethanol resistance, stretchability, and excellent bending resistance. Means for solving the problem includes providing a photocurable inkjet printing ink composition containing vinyl methyl oxazolidinone by 5 to 50% by mass relative to the entire ink composition, a monofunctional photopolymerizable monomer having a glass-transition temperature of 10° C. or less by 10 to 50% by mass relative to the entire ink composition, a colorant, and a photopolymerization initiator.
