Abstract
Abstract A unique opalescent color effect is produced on a substrate material utilizing a multicoat coating system. The base coat is a nonmetallic primary color coat having an N-4 to N-8 value on Munsell color chart. Directly on top of the base coat there is applied a transparent interference coat containing a polymeric binder and metal oxide encapsulated mica particles in a pigment to binder ratio of 0.06 to 0.13. On top of the previously applied coats is applied a transparent protective clear coat. The resultant coating in addition to being durable to the elements produces a unique opalescent color effect on the substrate material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A substrate material coated with at least three layers of a decorative, protective coating comprising a nonmetallic, primary base color coat having an N-4 to N-8 value on the Munsell color chart, a transparent interference coat comprising a polymeric binder containing metal oxide encapsulated mica in a pigment to binder ratio of 0.06 to 0.13 on the color coat, and a transparent protective polymeric clear coat on the transparent interference coat, the coating producing an opalescent color effect on the substrate material.
Claim 2
Dependent Claim
82 words
A substrate material coated with at least three layers of a decorative, protective coating comprising a nonmetallic, primary base color coat having an N-4 to N-8 value on the Munsell color chart, a transparent interference coat comprising a polymeric binder containing metal oxide encapsulated mica in a pigment to binder ratio of 0.06 to 0.13 on the color coat, and a transparent protective polymeric clear coat on the transparent interference coat, the coating producing an opalescent color effect on the substrate material.
Claim 3
Dependent Claim
23 words
The coated substrate of claim 1 wherein the primary base color coat has an N-5 to N-8 value on the Munsell color chart.
Claim 4
Dependent Claim
21 words
The coated substrate of claim 1 wherein the primary base color coat has an N-7 value on the Munsell color chart.
Claim 5
Dependent Claim
18 words
The coated substrate of claim 3 wherein the substrate is metal and the metal oxide is titanium dioxide.
Claim 6
Independent Claim
91 words
A method of coating a substrate with a plurality of layers of polymer comprising applying at least one layer of a nonmetallic primary color coat having an N-4 to N-8 value on a Munsell color chart, applying a transparent interference coat comprising a polymeric binder containing metal oxide encapsulated mica in a pigment to binder ratio of 0.06 to 0.13 on the base coat, and applying a transparent polymeric protective clear coat on the transparent interference coat, heating the applied coatings thus producing an opalescent color effect on the substrate material.
Claim 7
Independent Claim
91 words
A method of coating a substrate with a plurality of layers of polymer comprising applying at least one layer of a nonmetallic primary color coat having an N-4 to N-8 value on a Munsell color chart, applying a transparent interference coat comprising a polymeric binder containing metal oxide encapsulated mica in a pigment to binder ratio of 0.06 to 0.13 on the base coat, and applying a transparent polymeric protective clear coat on the transparent interference coat, heating the applied coatings thus producing an opalescent color effect on the substrate material.
Claim 8
Dependent Claim
21 words
The method of claim 5 wherein the primary color coat has an N-5 to N-8 value on the Munsell color chart.
Claim 9
Dependent Claim
19 words
The method of claim 5 wherein the primary color coat has an N-7 value on the Munsell color chart.
Claim 10
Dependent Claim
17 words
The method of claim 7 wherein the substrate is metal and the metal oxide is titanium dioxide.
