摘要： Benzylpyridinium or benzylammonium salts of a benzenesulfonate anion are useful as a proton-donating curing catalyst ion a resinous system capable of curing in the presence of such a catalyst. The catalyst is characterized by its heat-latent nature and thus does not impair the storage stability of the resinous system at an ambient temperature.
