    • An aqueous resin composition comprising a neutralization product of an isocyanurate group-containing maleinized alkyd resin having an acid value of 5 to 65 in an aqueous medium, said maleinized alkyd resin being prepared by maleinizing an alkyd resin having an acid value of not more than 10 and a hydroxyl value of not more than 10 which is the product of condensation reaction of(A) 20 to 60% by weight of at least one of drying or semi-drying oils and fatty acids,(B) 10 to 45% by weight of at least one tris(hydroxyalkyl) isocyanurate,(C) 0 to 45% by weight of at least one polyhydric alcohol other than the component (B),(D) 10 to 45% by weight of at least one polybasic acid, and(E) 0 to 15% by weight of at least one monobasic acidand an aqueous emulsion resin composition obtained by emulsion polymerization of a radical polymerizable unsaturated monomer in an aqueous medium in the presence of the aforesaid neutralization product. The above aqueous resin compositions can give a coating having excellent corrosion resistance and fast-drying property.
    • 一种含水树脂组合物,其包含在水性介质中含有酸值为5〜65的含异氰脲酸酯基的马来酸化醇酸树脂的中和产物,所述马来酸化的醇酸树脂通过使酸值不大于10的醇酸树脂 和(A)20至60重量%的干燥或半干性油和脂肪酸中的至少一种的缩合反应的产物的羟值为10以下,(B)10〜45重量% 的至少一种三(羟烷基)异氰脲酸酯,(C)0至45重量%的除(B)成分以外的至少一种多元醇,(D)10至45重量%的至少一种多元酸,以及 (E)0〜15重量%的至少一种一元酸和通过自由基聚合性不饱和单体在水性介质中在上述中和产物的存在下乳液聚合得到的水性乳液树脂组合物。 上述水性树脂组合物可以得到具有优异的耐腐蚀性和快干性能的涂层。
