Abstract

PURPOSE: The titled curing agent, obtained by adding a lactonic compound to a specific acid anhydride, having good crosslinkability, and capable of giving a cured article having improved flexibility, etc., with slight volatility, toxicity, and heat generation in curing.
CONSTITUTION: (B) One or more moles γ-butyrolactone, ε-caprolactone and/or β- propiolactone are added to (A) one mole compound containing a carboxylic acid anhydride group and a carboxylic acid group, e.g. trimellitic acid anhydride, to give the aimed curing agent. The amount of the lactone added is preferably 5 molecules or less based on one carboxylic acid group in the component (A). The addition reaction temperature is generally 50W240°C, preferably 18W230°C. The curing agent is effectively used with a curing accelerator, e.g. a tertiary amine, together.
