PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition having an excellent curing sensitivity to the active energy ray of low dose and an excellent storage stability.SOLUTION: An active energy ray-curable resin composition is an active energy ray-curable resin composition comprising: a carboxyl group pendant type polyester (meth)acrylate (A); a bis-carboxyl (meth)acrylate compound (B); and a photopolymerizable initiator (C). The active energy ray-curable resin composition is characterized in that the carboxyl group pendant type polyester (meth)acrylate (A) is one obtained by reacting following (i) to (iii) components and (A)/(B) is 100/0 to 12/88 (mass ratio). (i) Copolymerized polyester containing aromatic dicarboxylic acid of 40 mole% or more as the acid component and having a number average molecular weight of 1,000 to 10,000; (ii) carboxylic acid dianhydride; and (iii) a (meth)acrylate compound having one or more hydroxy groups within the molecule. |
