Abstract:
1. A light-curable ink composition for ink jet recording comprising a coloring material, a polymerizable compound, a polymerization and a photopolymerization initiator, wherein the coloring material contains at least C.I. Pigment Yellow 155, and the polymerizable compound contains at least a vinyl-ether-containing (meth)acrylate represented by general formula (I) below, with the vinyl-ether-containing (meth)acrylate present in an amount of 10 to 67% by mass based on a total mass of the ink composition: (where R 1 is a hydrogen atom or a methyl group, R 2 is a divalent organic residue having 2 to 20 carbon atoms, and R 3 is a hydrogen atom or a monovalent organic residue having 1 to 11 carbon atoms), wherein the polymerizable compound further contains a monofunctional (meth)acrylate, other than the vinyl-ether-containing (meth)acrylate, having either an aromatic skeleton or an alicyclic skeleton present in an amount of 10 to 60% by mass based on the total mass of the ink composition.
