(57) [Problem] To provide an epoxy resin curing catalyst capable of improving the stability of an epoxy resin composition at room temperature and at the time of compounding, and at the same time, maintaining the curing speed at the time of molding. An epoxy resin composition containing the same is provided. According to the present invention, a hydroxyl group-containing carboxylate of a bicyclic amidine is used as a catalyst for curing an epoxy resin. The epoxy resin composition according to the present invention, It contains 15 to 90 wt% epoxy resin, 5 to 80 wt% curing agent, and 0.2 to 10 wt% of a curing catalyst consisting of a hydroxyl-containing carboxylate of a bicyclic amidine. |
