Abstract
An acid anhydride-containing one package epoxy resin composition consisting indispensably of (1) an epoxy resin having two or more epoxy groups in one molecule, (2) an acid anhydride, (3) at least one of (a) a liquid latent curing accelerator, (b) a latent curing accelerator soluble in an epoxy resin having two or more epoxy groups in one molecule and (c) a latent curing accelerator soluble in an acid anhydride, and (4) a dispersible latent curing accelerator, wherein the ratio of (1) to (2) is from 0.8 to 1.2, defined as the number of acid anhydride equivalents/the number of epoxy equivalents, and the amounts of (3) and (4) each are from 0.1 to 10 parts by weight to 100 parts by weight of the epoxy resin. The composition has excellent infiltrability, storage stability and reactivity.
