(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, C1-18 monoalkylamino group, di C1-18 alkylamino group, morpholino group, piperidino group, methyl group or phenyl group; R1 and R2 independently each represent C1-12 alkyl group, C1-12 hydroxyalkyl group, C4-8 cycloalkyl group, C5-9 cycloalkylmethyl group or C5-9 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.
