Description

The study was conducted on the physical properties of an esterificated hemiacetal compound from a polyhydric carboxylic acid derivative and an epoxy resin, as well as on the crosslinking reaction, the cured film characteristic and storage stability. Consequently, it was possible to obtain an one-package thermosetting compound by using an esterificated hemiacetal compound from a polyhydric carboxylic acid derivative as a hardener. Based on the examination of crosslinking reaction in the presence of latent catalyst, it was suggested that a hemiacetal ester moiety directly attacked an epoxide to cleave it into a carboxy anion and an alkoxyalkyl cation preferentially. And, this reaction was found to advance stoichiometrically. It was possible to obtain a transparent and tough cured film according to this reaction. Furthermore, although the storage stability of the compound changed with the types of hardeners to be used, the improvement of the stability could be attained by the addition of alkyl vinyl ether even in the compound having inferior storage stability.
