Patent ID: 7432037

Claim:
A cured material, obtained by irradiating a curable resin composition with an active energy ray so that a moiety of a polymer block A contained in the curable resin composition is crosslinked, the curable resin comprising an addition polymerization-based block copolymer (I), an ethylenic unsaturated compound (II), and a photopolymerization initiator (III), wherein: the addition polymerization-based block copolymer (I) is selected from block copolymers comprising at least one polymer block A and at least one polymer block B, and the hydrogenated products thereof; the polymer block A comprises an aromatic vinyl compound unit containing at least 10% by mass of an alkylstyrene-derived structural unit (a) in which at least one alkyl group having 1 to 8 carbon atoms is bound to a benzene ring; and the polymer block B comprises a conjugated diene compound unit.
