Disclosed is a composition of an epoxy resin and about 0.1 to about 2 moles per epoxy equivalent weight of a beta -diketo amide having the general formula <IMAGE> where R1 is selected from the group consisting of alkyl to C20, aliphatic, cycloaliphatic, and arylalkyl, R2 is selected from the group consisting of hydrogen and R1, and R3 is selected from the group consisting of aryl and R1. A beta -diketo modified epoxy resin is also disclosed which has the general formula <IMAGE> The beta -diketo modified epoxy resin is used in resin compositions to increase their adherence to metals and to chelate with metal containing catalysts, forming self-catalyzed resins.
