The present invention deals with a novel aromatic di-isoimide chemical compound that has utility as a catalyst and as a curing agent in epoxy compositions. The di-isoimide serves effectively as a thermally activated latent catalyst in epoxy curing, thereby increasing shelf life, and avoids premature cross-linking. Novel laminated articles and printed wiring boards, including encapsulated printed wiring boards are also disclosed. The composition hereof also can be used as a flame retardant in thermoplastic and thermoset polymers.
