Abstract:
A cation-polymerizable coating composition comprising(A) a cation-polymerizable binder component consisting of (a) an epoxy group-containing compound selected from the group consisting of dicyclopentadiene dioxide, limonene dioxide, (3,4-epoxycyclohexyl)methyl 3,4-epoxycyclohexanecarboxylate, 3-vinlycyclohexene oxide, bis(2,3-epoxycyclopentyl) ether, compounds represented by the following formulae, ##STR25##and, optionally (b) an oxetane compound,(B) a modified dimethylsilicone oil with a number average molecular weight of 500-1,000,000 represented by the following formula: ##STR26##wherein each of a plurality of R.sup.a, R.sup.b and R.sup.c is identical or different and represents methyl group, phenyl group, --(CH.sub.2).sub.k --COOH (wherein k is an integer of 2-6), hydroxyl group, methoxy group, ethoxy group, acetoxy group or polyoxyalkylene group represented by the following formula (14) or (15) ##STR27##where R.sup.d and R.sup.c each represents a hydrogen atom, methyl group or acetyl group and x, y and z each represents an integer of 10-50, and at least one group among a plurality of R.sup.a, R.sup.b and R.sup.c represents a hydroxyl group, methoxy group, ethoxy group, acetoxy group or the above-mentioned --(CH.sub.2).sub.k --COOH, and m represents a number of 3-50 and n represents a number of 30-200, the modified dimethylsilicone oil having the phenyl group(s) or the polyoxyalkylene groups(s), and(C) a cation-polymerization initiator which forms a cation by irradiation or by heating.
