Abstract:
An active energy ray curable resin composition comprising: urethane poly(meth)acrylate (A) synthesized from a raw material including a polyisocyanate and a hydroxy group-containing (meth)acrylate; (meth)acrylate (B) having five or more functional groups; a photopolymerization initiator (C1) having an absorption coefficient per unit weight of 50000 ml/g·cm or more when measured in methanol at 254 nm; a photopolymerization initiator (C2) other than the (C1) having an absorption coefficient per unit weight of 50000 ml/g·cm or more when measured in methanol at 302 nm; a photopolymerization initiator (C3) other than the (C1) and the (C2) having an absorption coefficient per unit weight of 100 ml/g·cm or more when measured in methanol at 405 nm; and an ultraviolet absorbing agent (D).
