Abstract
Provided is a convenient method for synthesizing quaternary ammonium salts which are useful as curing catalysts for one-part thermosetting resin compositions which maintain storage stability at room temperature. The ammonium salts are synthesized by direct reaction of a benzyl alcohol or a benzyl alkyl ether optionally having on the benzene ring and/or at .alpha.-position one or more substituent groups inert to the intended reaction, with a corresponding strong-acid salt of a tertiary amine.
