PROCESS FOR PRODUCING A CURABLE COMPOSITION

摘要

Compositions capable of curing at ambient or slightly elevated temperatures comprise (i) a compound containing in the molecule at least two hydroxyl groups, in particular a hydroxyl group-bearing addition polymer, (ii) a compound containing in the molecule at least two cyclic carboxylic anhydride groups and (iii) a compound containing in the molecule at least two epoxide groups. The compositions may optionally also contain a catalyst for the reaction between epoxide groups and carboxylic groups. The compositions are of particular value as the basis of room-temperature-curing coating compositions.
