Abstract

PURPOSE: Titled composition, quick-curing and excellent in storage stability, which is prepared by compounding an epoxy resin with a curing agent, prepared by melting and mixing a specified phenol compound and a tetrasubstituted arsonium-tetrasubstituted borate compound.
CONSTITUTION: (A) 100pts.wt. of a phenol compound such as a novolak resin, having at least three phenolic hydroxy groups per molecule and (B) 1W20pts.wt. of tetrasubstituted arsonium-tetra-substituted borate compound of the formula (wherein R1W4 are alkyl, alkenyl or allyl; R5 is phenyl or substituted phenyl), are molten and mixed at 80W180°C, to obtain a curing agent. Then an epoxy resin is compounded with said curing agent in such a proportion that a ratio of the epoxy group equivalent of the resin to the hydroxy group equivalent of the curing agent, is 1:0.7W1.2.
