Abstract
Paint compositions containing (A) a vinyl type copolymer obtained by polymerizing (i) specific silicone type vinyl monomers 1-50% by weight, (ii) vinyl monomers containing hydroxyl groups 5-60% by weight, and (iii) other vinyl monomers 5-80% by weight, (B) specific hydroxyl-group-containing silicone type compounds, and (C) a hardening agent that allows reaction with hydroxyl groups. Paint films can be formed which have excellent water-repellence and oil-repellence, and in which there is no lowering of water-repellence or oil-repellence when they are exposed for long periods in natural environments.
Claims3
Paint composition comprising (A) a vinyl type copolymer obtained by polymerizing
- (i) 1-50% by weight of a silicone type vinyl monomer represented by the general formula ##STR5## in the formula X is a hydrogen atom or a methyl group, R.sup.1 is a methyl group or a phenyl group, k is a number 1-5, and m is a number 3-150
- (ii) 5-60% by weight of a vinyl monomer containing a hydroxyl group, and (iii) 5-80% by weight of another vinyl monomer,
- (B) a silicone compound represented by the general formula ##STR6## in the equation either one of Y.sup.1 and Y.sup.2 is a hydroxyl group and the remaining one is a hydroxyl group or a methyl group;
- R.sup.2 is a methyl group or a phenyl group, and n is a number 3-150, and
- (C) a hardening agent which allows reaction with hydroxyl groups.
