Abstract:
A composite film formed by applying a coating agent to at least one side of an organic resin film and thereafter curing the coating agent, the coating agent being a high energy radiation curable coating agent composition which consists essentially of(A) an amino-group-containing alkoxysilane having the general formula: wherein R1 and R2 are divalent hydrocarbon groups having from 1-12 carbon atoms, R3 is an alkyl group having from 1-6 carbon atoms, a cycloalkyl group, or a phenyl group, and R4 is a hydrolyzable group selected from the group consisting essentially of alkoxy groups and aryloxy groups, Q1, Q2 and Q3 are selected from te group consisting of (i) groups having the general formula Xâ€”C6H4â€”CH2â€”, (ii) hydrogen atoms, and (iii) hydrochlorides of (i), wherein X is a vinyl group or a hydrogen atom, with the proviso that at least one of said groups is a group (i) and wherein n has a value of 0, 1 or 2, and a has a value of 0, 1 or 2, and, (B) an organic compound which has the general formula: wherein R5 is a residue of an organic polyhydric alcohol containing alcoholic hydroxyl groups bonded to different carbon atoms, or a residue of an ester formed by such an organic polyhydric alcohol and a polybasic acid, R6 is a hydrogen atom or a methyl group, and b is an integer from 2-6.
