<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition capable of providing a cured coated film having high surface hardness, excellent mar resistance, a very small curling property derived by small shrinkage on curing, and further a self-restoring property by which self-restores scratches once occurred. <P>SOLUTION: The active energy ray-curable resin composition includes: components (A), (B) and (C), wherein a mass ratio between the component (A) and (B) ranges from 10:90 to 90:10, and a content of the component (C) with respect to the total mass of the components (A) and (B) ranges from 0.1 to 20 mass%. Wherein the component (A) is urethane (meth)acrylate obtained by reaction between (meth)acrylate (a1) and polyisocyanate (a-2), the (meth)acrylate (a-1) is obtained by adding one to twenty moles of an alkylene oxide having two to four carbons to a (meth)acrylate having one hydroxy group and three or more (meth)acryloyl groups in one molecule; the component (B) is a multi-functional (meth)acrylate; and the component (C) is a photopolymerization initiator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
