    • PURPOSE: A heat-hardenable paint composition is provided, which can form paint films having excellent acid resistance, weather resistance and heat resistance and yellowing resistance. CONSTITUTION: A heat-hardenable paint composition comprises (A) polyol which has in each molecule two or more sterically protected secondary hydroxyl groups, being polyol obtained by means of an esterification reaction of an epoxy group-containing compound which has one epoxy group and which does not have a polymerizable unsaturated bond and a carboxyl group-containing compound which has two or more carboxyl groups; and (B) 1,3,5-triazine-2,4,6-tris-ceramic acid ester which can be represented by the formula C3N3(NHCOOR)3 or an oligomer thereof, wherein the mol ratio of the secondary hydroxyl groups originating from the (A) component: the NHCOOR groups originating from the (B) component in the composition is from 1: 3 to 3: 1. (In the formula 1, R represents an alkyl group of C1-20, an aryl group of C6-20 or an aralkyl group of C7-20). The composition can comprise further (C) acrylpolyol containing primary hydroxyl groups, wherein the mol ratio of the secondary hydroxyl groups originating from the (A) component: the hydroxyl groups originating from the (C) component in the composition is from 100: 0 to 100: 100.
    • 目的:提供一种可热硬化的涂料组合物,其可以形成具有优异的耐酸性,耐候性和耐热性以及耐黄变性的漆膜。 构成:可热硬化的涂料组合物包含(A)在每个分子中具有两个或多个空间保护的仲羟基的多元醇,其是通过具有一个环氧基的含环氧基的化合物的酯化反应得到的多元醇, 不具有聚合性不饱和键和具有两个以上羧基的含羧基化合物; 和(B)可由式C 3 N 3(NHCOOR)3表示的1,3,5-三嗪-2,4,6-三 - 陶瓷酸酯或其低聚物,其中起始的仲羟基的摩尔比 (A)成分:来自组合物中(B)成分的NHCOOR基团为1:3〜3:1(式1中,R表示C1-20的烷基, C6-20或C7-20的芳烷基)。 组合物可以包含另外的(C)含有伯羟基的丙烯基多元醇,其中源自(A)成分的仲羟基的摩尔比:来自组合物中(C)成分的羟基为100:0〜 100:100。
