Abstract

An article is coated with a multi-layer coating having a stainless steel color. The coating comprises a polymeric layer on the article surface, a refractory metal or refractory metal alloy strike layer on the polymeric layer, a color layer containing a refractory metal oxide or refractory metal alloy oxide having a substoichiometric oxygen content on the strike layer, and a refractory metal oxide or refractory metal alloy oxide having a substantially stoichiometric oxygen content layer on said color layer.

Claims

1. An article having on at least a portion of its surface a multi-layer coating having the appearance of stainless steel comprising:

a polymeric layer;

color layer comprised of a refractory metal oxide or refractory metal alloy oxide wherein the oxygen content of said refractory metal oxide or refractory metal alloy oxide is substoichiometric.

2. The article of claim 1 wherein said substoichiometric oxygen count is from about 5 atomic percent to about 25 atomic percent.

3. The article of claim 2 wherein said substoichiometric oxygen content is from about 8 atomic percent to about 18 atomic percent.

4. The article of claim 1 wherein a strike layer comprised of a refractory metal or refractory metal alloy is intermediate said polymeric layer and said color layer.

5. The article of claim 4 wherein a layer comprised of refractory metal oxide or refractory metal oxide having a substantially stoichiometric oxygen content is on said color layer.

6. The article of claim 4 wherein a layer comprised of the reaction products of a refractory metal or refractory metal alloy, oxygen and nitrogen is on said color layer.

7. The article of claim 1 wherein a layer comprised of refractory metal oxide or refractory metal alloy oxide having a substantially stoichiometric oxygen content is on said color layer.

8. The article of claim 1 wherein a layer comprised of the reaction products of a refractory metal or a refractory metal alloy, oxygen and nitrogen is on said color layer.

9. The article of claim 1 wherein said polymeric layer is comprised of an epoxy urethane.

10. An article having on at least a portion of its surface a multi-layer coating having the color of stainless steel comprising:

a polymeric layer on the surface of said article;

a color layer comprised of a refractory metal oxide or refractory metal alloy oxide having a substoichiometric oxygen content of from about 5 to about 25 atomic percent on said at least one electroplated layer; and

a refractory metal oxide or refractory metal alloy oxide having a substantially stoichiometric oxygen content on said color layer.

11. The article of claim 10 wherein said substoichiometric oxygen content is from about 8 to about 18 atomic percent.

12. The article of claim 10 wherein a layer comprised of refractory metal or refractory metal alloy is intermediate said at least one electroplated layer and said color layer.

13. The article of claim 12 wherein said polymeric layer is comprised of epoxy urethane.

14. The article of claim 10 wherein a layer comprised of the reaction products of refractory metal or refractory metal alloy, oxygen and nitrogen is on said color layer.

15. The article of claim 10 wherein a layer comprised of refractory metal oxide or refractory metal alloy oxide having a substantially stoichiometric oxygen content is on said color layer.
