The invention provides a coating varnish composition comprising (A) a polymer obtained by polymerizing (a) at least one unsaturated acid anhydride and (b) at least one other unsaturated monomer, and (B) at least one additive selected from triazole derivatives, benzothiazole derivatives, thiadiazole derivatives, polyethers and carboxylic acid anhydride derivatives and an antifouling coating composition comprising said coating varnish and an antifouling agent containing a coppercompound as major component. Using such compositions the risks of poisoning associated with organotin copolymers are avoided and there are obtained coatings of a coating consuming property and antifouling performance comparable with those of the organotin copolymers which do not gel even when mixed with a copper compound.
本发明提供了一种涂料清漆组合物,该组合物包含(A)通过聚合(a)至少一种不饱和酸酐和(b)至少一种其他不饱和单体而得到的聚合物,和(B)至少一种选自三唑衍
