Abstract:
1. A radiation curable resin composition comprising: a composite resin (A) in which a polysiloxane segment (a1) having a polymerizable double bond, which has a structural unit represented by a general formula (1) and/or a general formula (2) as well as having a silanol group and/or a hydrolyzable silyl group, and a vinyl-based polymer segment (a2) having an alcoholic hydroxyl group are bound to each other through a bond represented by a general formula (3); a polyisocyanate (B), and a photopolymerization initiator, wherein the content of said polysiloxane segment (a1) is from 10 to 60% by weight with respect to the total solid content of the curable resin composition, the content of the polyisocyanate (B) is from 5 to 50% by weight with respect to the total solid content of the curable resin composition, and the content of the polymerizable double bond in said polysiloxane segment (a1) is from 3 to 20% by weight (in said general formulas (1) and (2), R (in the general formula (3), the carbon atom constitutes a part of said vinyl-based polymer segment (a2), and the silicon atom which is only bound to the oxygen atom constitutes a part of said polysiloxane segment (a1)).
