Zusammenfassung:	PURPOSE:To obtain titled curing accelerator capable of exibiting rapid curing rate with a small application when incorporated in epoxy resins and of providing high-quality cured products under mild curing conditions, comprising a specific quaternary ammonium salt and an acid anhydride. CONSTITUTION:The objective curing accelerator comprising (A) a quaternary ammonium salt of formula[Y is a chlorobutenyl group (CH3CCl=CHCH2-, CH3CH=CClCH2-, CHCl=CHCH2CH2-, CH2=CClCH2CH2-, etc.); R1, R2, R2, and R3 are each 1-20C alkyl, alkenyl, oxyalkyl, phenyl, etc.; X is an anionic group as counter ion], (e.g, 2-chlorobutenyl-2-trimethylammonium chloride) and (B) an acid anhydride (e.g, methylnadic acid anhydride). The above curing accelerator is incorporated in an epoxy resin followed by heating to obtain an epoxy resin cured product.
