摘要：
A binder for a coating composition is a combination of(a) polymers containing intramolecular carboxylic anhydride groups and having an average molecular weight of from 500 to 25,000 and(b) organic compounds containing 4,5-dihydrooxazole groups in a quantity corresponding to an equivalent ratio of carboxylic anhydride groups to 4,5-dihydrooxazole groups of from 0.5:1 to 2:1, and contains from 0.005 to 5% by weight, based on the weight of components (a) and (b), of ammonia, a primary amine or secondary amine.
