AbstractA photocurable composition comprising a first copolymer having a recurring unit of general formula (I): ##STR1## wherein Ar represents a substituted or unsubstituted phenyl group, R1 represents a lower alkyl group, and m1 and m2 are positive numbers with m1 being greater than or equal to m2 ;and a second copolymer having a recurring unit of general formula (II): ##STR2## wherein R2 represents a lower alkyl group, X represents a hydrogen atom or a methyl group, and R3 represents an isobutyl group, a t-butyl group or a --CH2 Ar group where Ar represents a substituted or unsubstituted phenyl group and when R3 is --CH2 Ar, R2 can also be t-butyl and isobutyl, and n1, n2 and n3 are positive numbers but n1 can be zero and (n1 +n2)/n3 equals to about 0.5 to 20; and containing suitable amounts of a cross-linking agent and a photoactivator.
