Abstract
PURPOSE: To eliminate the after-treatment, e.g. filtration, etc. and to prevent the coloration of an amide compound, by adding a β-diketone compound to an amide compound useful as an epoxy hardener, adhesive, etc.
CONSTITUTION: An amide compound is incorporated with 0.01W10wt.% of a β- diketone compound, e.g. acetylacetone, hexafluoroacetone, benzoylmethane, etc., of formula (R and R' are 1W5C alkyl, 1W5C fluorine-substituted alkyl, phenyl, monofunctional heterocyclic group, e.g. furyl or thienyl group, and stabilized to coloration in preparing the compound from a carboxylic acid, e.g. a polymerized fatty acid, monocarboxylic acid, etc., and a polyamine or at any time after the preparation, preferably during a period wherein the compound can be maintained at 60W 204°C (110W240° for a solid resin) for 30 min or longer.
