| 摘要 |
There is disclosed a cation-polymerizable coating composition characterized by containing(A) a cation-polymerizable binder component consisting of (a) an epoxy group-containing compound and, as necessary, (b) an oxetane compound,(B) a modified dimethylsilicone oil with a number average molecular weight of 500-1,000,000 having a hydroxyl group(s) bonded directly to a silicon atom, a hydrolyzable functional group(s) bonded directly to a silicon atom and capable of forming a hydroxyl group(s) bonded directly to a silicon atom by hydrolysis, or a carboxyl group(s), and(C) a cation-polymerization initiator which forms a cation by irradiation or by heating. Said coating composition is suitable particularly for coating cans capable of forming a coating film having excellent adhesivity, processibility, hardness, initial lubricity and lubricity after the retort treatment.
