Method for improving storage stability of epoxy ester thermosetting resins with thiuram compounds

摘要

A method for improving storage stability of a thermosetting resin, which comprises adding a thiuram compoound to the thermosetting resin comprising a reaction product of an epoxy resin with an &agr;,&bgr;- unsaturated monocarboxylic acid dissolved in a polymerizable olefinic unsaturated compound, said thiuram compound having in one molecule thereof at least one atomic group expressed by the following general formula I: ##STR1## wherein p is an integer of 1 to 4, and being used in an amount of 0.0001 to 2.0 parts by weight per 100 parts by weight of said reaction product.
