Abstract

PURPOSE: The title curing agent having improved curing properties to an epoxy resin, heat resistance, and low toxicity, consisting of a carboxylic acid-type polyester obtained by reacting tri-or polybasic acid anhydride with a polyol in a specific ratio.
CONSTITUTION: A) 0.7W1.3 moles of a tri-or polybasic acid anhydride, e.g., trimellitic acid anhydricde, is reacted with B) one hydroxyl group equivalent of a tri-or polyhydric alcohol, e.g., pentaerythritol, in the presence of a solvent, e.g. para-hydroxybenzoic acid, capable of dissolving the components A and B, and the polyester to be formed, at 130°CW200°C, and for 10W120 minutes to give the desired carboxylic acid-type polyester used as a curing agent.
EFFECT: Improved long-time strage stability.
