Composition of acrylic polycarboxylic acid, polyester polycarboxylic acid and polyepoxide |
摘要 |
A high-solid curable resin composition which forms a coated film having excellent acid rain resistance, mar resistance and appearance comprises:(a) 10 to 70% by weight of an acrylic polycarboxylic acid having 2 or more carboxyl groups per molecule on an average, an acid value of 5 to 300 mg KOH/g (solid) and a number-average molecular weight of 500 to 8000;(b) 5 to 70% by weight of a polyester polycarboxylic acid having an acid value of 50 to 350 mg KOH/g (solid), a number-average molecular weight of 400 to 3500 and a ratio of weight-average molecular weight to number-average molecular weight of 1.8 or less, which is obtained by reacting a polyester polyol having 3 or more hydroxyl groups with an acid anhydride group-containing compound; and(c) 10 to 80% by weight of a polyepoxide having an epoxy equivalent of 50 to 700 and a number-average molecular weight of 200 to 10000; provided that the amounts of the components (a) to (c) being based on the weight of the total solid contained in the curable resin composition.
