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.
