1. A curable composition comprising the following two components:
(A1) a vinyl polymer which has a main chain produced by living radical polymerization techniqiue, and has at least one crosslinking silyl group of the general formula (1) on the average per molecule:
—[Si(R1)2-b(Y)bO]m—Si(R2)3-a(Y)a  (1)
wherein R1 and R2 may be the same or different and each represents an alkyl group containing 1 to 20 carbon atoms, an aryl group containing 6 to 20 carbon atoms, an aralkyl group containing 7 to 20 carbon atoms, or a triorganosiloxy group of the formula (R′) 3SiO—, where R′ represents a univalent hydrocarbon group containing 1 to 20 carbon atoms and the plurality of R′ groups may be the same or different, and when two or more R1 or R2 groups are present, the plurality of groups may be the same or different; Y represents a hydroxyl group or a hydrolyzable group and, when two or more Y groups are present, they may be the same or different; a represents an integer of 0, 1, 2 or 3; b represents an integer of 0, 1 or 2; m is an integer of 0 to 19; with the condition that the relation of a+mb≧1 is satisfied and
(B) a photocurable substance.
