    摘要： PURPOSE: To improve storage stability and low-temp. curability without incorporating any halogen by using a particular compd. for curing an epoxy resin. CONSTITUTION: Naphthylene 1,5-diisocyanate is reacted with a di(lower alkyl) amine in an at least stoichiometric amt. to prepare a curing accelerator for an epoxy resin, comprising a compd. of the formula (wherein R1 to R4 represent each a 1-3C alkyl). An epoxy resin is mixed with 2 to 15 pts.wt. dicyandiamide and the curing accelerator in an amt. of 1 to 20 pts.wt. based on the epoxy resin.
