摘要： An object achieved by the present invention is to provide an active energy ray-curable ink composition that has flexibility (stretch resistance) at a low temperature while maintaining blocking resistance at room temperature, forms a printed material with excellent flexibility, and also has excellent durability against stacking of printed materials. According to the present invention, the active energy ray-curable ink composition is a composition including 35% to 50% by mass of a monomer A represented by General Formula (1) with respect to a total amount of the composition, a monomer B having a polymerizable unsaturated double bond and a structure represented by General Formula (2), and at least one polyfunctional polymerizable compound selected from urethane (meth)acrylate or amino (meth)acrylate.

摘要： To provide an actinic-ray-curable ink set for ink-jet recording which is excellent in thick-film curability even when a UV-LED lamp is used as a light source, and has uniform curing sensitivity across different colors. The present invention relates to an actinic-ray-curable ink set for ink-jet recording, characterized in that a cyan ink contains a phthalocyanine pigment, a radical polymerizable compound, and less than 10% by mass of a photopolymerization initiator based on the total amount of the cyan ink, a magenta ink contains a quinacridone-based pigment, a radical polymerizable compound, and less than 5% by mass of a photopolymerization initiator based on the total amount of the magenta ink, a yellow ink contains an azo pigment, a radical polymerizable compound, and less than 10% by mass of a photopolymerization initiator based on the total amount of the yellow ink, and a black ink contains a carbon black, a radical polymerizable compound, and less than 12% by mass of a photopolymerization initiator based on the total amount of the black ink.
