Abstract
A resin for an active energy ray curable ink contains a rosin-modified unsaturated polyester resin (A). The rosin-modified unsaturated polyester resin (A) is a reaction product of a material component containing rosins (a), α,β-unsaturated carboxylic acids (b), and polyols (c); the mole ratio of an unsaturated bond based on the α,β-unsaturated carboxylic acids (b) with respect to the total amount of the material component is 0.50 mol/kg or more and 2.00 mol/kg or less; the rosins (a) contain a stabilization-treated rosin at a ratio of 90 mass % or more with respect to the total amount of the rosins (a); the α,β-unsaturated carboxylic acids (b) contain α,β-unsaturated dicarboxylic acids; and the polyols (c) contain a trihydric or more alcohol.
