Photocurable inkjet ink composition

Abstract

A photocurable inkjet ink composition containing the following A to E, having a viscosity of 100 cps or less and a surface tension of 32.0 mN/m or less: A. a polymeric photoinitiator having ethylenic unsaturated bonds, B. a thioxanthone-based compound having photosensitization action, C. a (meth)acrylate-based polymer compound, D. a (meth)acrylamide-based compound and/or aminobenzoate compound, and E. a surface additive. The photocurable inkjet ink composition is made to have appropriate viscosity as an inkjet ink composition while also realizing sufficiently high reactivity to reduce migration substances generating from the coating film of the cured photocurable inkjet ink composition.
