    • The invention relates to a coating agent composition comprising an isocyanate-group-containing prepolymer obtained by reacting a polyol comprising a polyoxyalkylene polyol having 2-4 hydroxyl groups on average, an oxyethylene group content of 85-100% by mass based on all oxyalkylene groups (100% by mass), and an arithmetic-average molecular weight of 800-2,500 with an alicyclic isocyanate and/or an aliphatic isocyanate in the presence of an organic acid bismuth salt catalyst, the isocyanate(s) being used in such an amount as to result in an isocyanate index of 150-300. The invention can provide a coating agent composition which forms a coating film or film having moisture permeability, excellent in mechanical properties and yellowing resistance, having laundering durability and resistance to sweat deterioration, and containing no organotin compounds.
    • 本发明涉及包含含异氰酸酯基的预聚物的涂料组合物,其通过使包含平均具有2-4个羟基的聚氧化烯多元醇的多元醇,基于所有氧化烯基的氧乙烯基含量为85-100质量% (100质量%),在脂肪族异氰酸酯和/或脂肪族异氰酸酯的存在下,在有机酸铋盐催化剂的存在下,算术平均分子量为800〜2500,异氰酸酯的用量为 导致异氰酸酯指数为150-300。 本发明可以提供一种涂层剂组合物,其形成具有透湿性,机械性能和耐黄变性优异,具有洗涤耐久性和耐汗水劣化,不含有机锡化合物的涂膜或膜。
