The present invention provides an antifouling pain composition comprising a non-dispersion resin having a core-shell structure which is constituted of (a) a hydrophilic core component comprising a polymer of ethylenically unsaturated monomers of which 5-75% by weight comprise free acid groups and ≦3% by weight comprises silyl ester groups, (b) a shell component comprising a polymer of ethylenically unsaturated monomers of which <3% by weight comprises free acid groups or silyl ester groups, said resin having an acid value 15-400 mg KOH/g wherein the core component accounts for ≧80% of the acid value of the resin, said paint composition comprising rosin wherein S90% by weight of the rosin has conjugated, non-aromatic double bonds, and ≧25% thereof being metal resinate which constitutes 1-40% by wet weight of the composition, the dry weight ratio between (i) NAD and (ii) rosin and metal resinates being 100:15 to 15:100.
本发明提供了一种防污漆组合物,该组合物由具有核壳结构的非分散树脂组成,该核壳结构由以下部分组成:(a)亲水性核组分,该核组分由乙烯基不饱和单体的聚合物组成,其中5-75%(重量)由游离酸基团组成,≦3%(重量)由硅酯基团组成;(b)壳组分,该壳组分由乙烯基不饱和单体的聚合物组成,其中<3%(重量)由游离酸基团或硅酯基团组成、所述树脂的酸值为 15-400 mg KOH/g,其中核心组分占树脂酸值的 ≧80%,所述涂料组合物包括松香,其中 S90%(重量)的松香具有共轭、非芳香族双键,以及 ≧25%(重量)的金属树脂酸盐,占组合物湿重的 1-40%,(i)NAD 与(ii)松香和金属树脂酸盐之间的干重比为 100:15 至 15:100。
