Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
151 words
A method for coating a substrate which comprises (1) applying onto the substrate a composition comprising (A) an epoxy resin polymerizable to a high molecular weight state selected from epoxy monomer, epoxy prepolymer, oxirane containing organic polymer and mixtures thereof, and (B) an effective amount of a 1,3-dicarbonyl chelate of the formula, ##STR6## where X is a main row element selected from Group IIIa, IVa and Va, J is a divalent organo radical having 3 to 42 carbon atoms, M is an element selected from Sb, As, P and B, and Cl, Q is halogen or oxygen, n is an integer equal to 2 or 3, y is an integer equal to 1 or 2, and a is an integer equal to 4 to 6 or the valence of M, (2) subjecting the resulting treated substrate of (1) to ultraviolet radiation until a tack-free cured coating is obtained on said substrate.
