Abstract
A coating composition and method for protecting anodized aluminum, and the coated product are disclosed, wherein the coating comprises a crosslinking agent; a film-forming resin selected from the group consisting of polyester polymers, thermosetting acrylic polymers, and mixtures thereof; and an epoxy silane. The combination provides exceptional adhesion of the coating to anodized surfaces as well as good hardness.

AMENDED CLAIMS
I received by the International Bureau on 15 September 1994 (15.09.94); original claims 17-27 cancelled; remaining claims unchanged (1 page)]
11. The coated product of claim 10 wherein the acrylic/acrylamide copolymer is further characterized as a copolymer of ethyl acrylate, styrene, N-butoxymethyl acrylamide, and methacrylic acid.
12. The method of claim 11 further including polyester polymer as a modifying resin.
13. The method of claim 9 wherein the film-forming resin includes polyester further characterized as being the reaction product of trimethylpentanediol, adipic acid, and isophthalic acid.
14. The method claim 9 wherein the crosslinking agent is me1amine.
15. The method of claim 14 wherein the melamine is methoxylated melamine.
16. The method of claim 9 wherein the silane is selected from the group consisting of gamma-glycidoxypropyltrimethoxysilane and beta- (3,4-epoxycyclohexyl) -ethyltrimethoxysilane.
