CURATIVE COMPOSITION AND ONE-COMPONENT COATING COMPOSITION

摘要

PURPOSE: To obtain a curative compsn. which is suitable for a coating compsn. which inhibits the dissolution of copper from the material of a substrate, a container, etc., and does not yellow on baking by using, as the main components, a specific compd., such as a benzotriazole compd. or an aminotriazole compd., and a blocked polyisocyanate. ;CONSTITUTION: This compsn. contains, as the main components, a blocked polyisocyanate and at least one compd. selected from among a benzotriazole compd. of formula I (wherein R¹ to R⁵ are each independently H, an alkyl, an aryl, carboxyl, an alkyl ester, or an aryl ester group, a halogen, an alkali metal, etc.) having the nitrogen atom at the 2-position unsubstd., an aminotriazole compd. of formula II (wherein R¹ and R² are each the same as R¹ to R⁵ in formula I; and R³ is H or an acyl), and a polycarboxylic acid compd. The compsn. and a polyol component are used as the main components to give a one-component coating compsn.;COPYRIGHT: (C)1996,JPO
