    摘要: A curable resin is composed ofA. an epoxy resin andB. a pyrylium salt as a catalyst, with or withoutC. a metal chelate or metal salt as a co-catalyst.Preferred pyrylium salts are those of the formula ##STR1## Preferred co-catalysts are acetylacetonates, stearates, benzoates, naphthenates, octoates or phthalates of Cu.sup.++, Co.sup.++, Co.sup.+++, Fe.sup.+++ or Al.sup.+++. The resin compositions may be used to produce coatings and moldings.
