摘要:
Provided are a latent curing agent that gives an epoxy resin composition with improved storage stability and low-temperature curability; and a curable epoxy resin composition prepared by mixing the said curing agent and an epoxy compound. The epoxy resin composition has improved storage stability, and cures at lower temperatures for a shorter period of time than conventional ones. The latent curing agent for epoxy resin comprises two components, (A) a radically polymerized polymer of a monomer having at least a polymerizable double bond, which has at least a tertiary amino group in the molecule, and (B) a polymer having at least a hydroxyl group in the molecule, and forms a solid solution that is solid at 25° C.
