Abstract
To provide an active energy ray-curable ink composition that contains high rates of raw materials derived from biomass and can maintain basic characteristics, such as compatibility.Provided is an active energy ray-curable ink composition containing a pigment, a compound having ethylenically unsaturated bonds, and a rosin-modified alkyd resin, wherein the rosin-modified alkyd resin is a condensed polymer of an acid ingredient containing a resin acid, a fatty acid, and a polybasic acid with a polyhydric alcohol, and has a solubility parameter (sp) value of 9.0 to 11.0 (cal/cm3)1/2 as measured by turbidimetric titration and an acid value of 1 to 50 mg KOH/g.
