USPTO Abstract
(Object) It is to provide an epoxy/acid anhydride composition comprising an epoxy compound and an acid anhydride serving as a curing agent wherein a substituted triazine of a specific structure is employed as a curing accelerator to thereby impart a long pot life, a high storage stability and good working characteristics to the composition and cause no defect such as bubbling or cracking in the cured resin. (Constitution of the invention) An epoxy/acid anhydride composition characterized by containing, as a curing accelerator, a substituted triazine of the formula [ ] (wherein X is an amino group, C 1-18 monoalkylamino group, di C 1-18 alkylamino group, morpholino group, piperidino group, methyl group or phenyl group; R 1 and R 2 independently each represent C 1-12 alkyl group, C 1-12 hydroxyalkyl group, C 4-8 cycloalkyl group, C 5-9 cycloalkylmethyl group or C 5-9 methylcycloalkyl group) in an epoxy/acid anhydride composition in which an epoxy compound and an acid anhydride-curing agent are contained, and an epoxy/acid anhydride resin composition prepared by thermosetting the epoxy/acid anhydride composition.
