<p>PROBLEM TO BE SOLVED: To provide color ink used for manufacturing an insert molding molded article without containing a solvent. SOLUTION: The color ink is ultraviolet curable color ink and a film with a thickness of 100μm molded by curing the vehicle constituting the color ink by ultraviolet rays has a breaking strength of 1.0 kg/cm or more and an elongation at break of 130% or more. This color ink can be obtained by adding a photopolymerization reaction initiator accelerating photopolymerization reaction or a photopolymerization reaction sensitizer, a pigment for coloration and an additive for adjusting ink properties or printability to a composition containing a photopolymerization reactive oligomer such as urethane(meth)acrylate, polyester(meth)acrylate or the like as an oligomer and a photopolymerization reactive monomer such as N-vinyl caprolactam, acroyl morpholine or the like as a monomer.</p> |
