Abstract
To provide an active energy ray-curable ink composition that increase the content of raw materials derived from biomass and contains a material having superior pigment dispersibility, such as a rosin-modified phenol resin. An active energy ray-curable ink composition containing a compound having one or more ethylenically unsaturated bonds, a specific resin, and a specific liquid ingredient is provided, wherein the specific resin is at least one selected from the group consisting of rosin-modified phenol resins, rosin-modified maleic acid resins, rosin-modified alkyd resins, gilsonite resins, and asphalt resins, and the specific liquid ingredient is fat and oil that is derived from animals or vegetables or a modified product thereof having no ethylenically unsaturated bonds and a solubility parameter value (hereinafter referred to as sp value) of 9.0 (cal/cm3)1/2 to less than 11.0 (cal/cm3)1/2 as measured by turbidimetric titration.
