Abstract

The invention relates to heat curable epoxy resin compositions consisting of an epoxy resin containing, on average, more than one epoxide group per molecule, an aromatic onium salt as catalyst, a copper complex compound as co-catalyst, and a light stabilizer. These compositions are less sensitive to UV irradiation and have a good shelf life at room temperature as well as a good high temperature reactivity.
