ABSTRACT:
A thermosetting resin composition is produced by heat treating a mixture of a polyaddition thermosetting resin, a silicic compound of the formulawherein R is an organic group containing a functional group that causes an addition reaction with the curing agent and R5and R6are independently a methyl group or an ethyl group, and water and adding a curing agent of the polyaddition thermosetting resin to the mixture that has undergone heat treatment.
