Abstract
Abstract A unique opalescent color effect is produced on a substrate material utilizing a multicoat coating system. The primer base coat is a nonmetallic primary color coat having an N-4 to N-8 value on the Munsell color chart. Directly on top of the primer 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 primary base color coat being a high solids content primer layer having good corrosion resistance, good adhesion, etc. 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
88 words
A substrate material coated with at least three layers of a decorative, protective coating comprising a non-metallic primer coat having an N-4 to N-8 value on the Munsell color chart, said primer coat applied onto the substrate material, 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 primer 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
88 words
A substrate material coated with at least three layers of a decorative, protective coating comprising a non-metallic primer coat having an N-4 to N-8 value on the Munsell color chart, said primer coat applied onto the substrate material, 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 primer 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
21 words
The coated substrate of claim 1 wherein the primer coat has an N-5 to N-8 value on the Munsell color chart.
Claim 4
Dependent Claim
18 words
The coated substrate of claim 1 wherein the substrate is metal and the metal oxide is titanium dioxide.
Claim 5
Independent Claim
94 words
A method of coating a substrate with a plurality of layers of polymer comprising applying at least one layer of a non-metallic primer coat having an N-4 to N-8 value on the Munsell color chart directly onto the substrate, 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 primer 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 6
Independent Claim
94 words
A method of coating a substrate with a plurality of layers of polymer comprising applying at least one layer of a non-metallic primer coat having an N-4 to N-8 value on the Munsell color chart directly onto the substrate, 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 primer 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
Dependent Claim
17 words
The method of claim 4 wherein the substrate is metal and the metal oxide is titanium dioxide.
Claim 8
Dependent Claim
20 words
The method of claim 4 wherein the primer coat has an N-5 to N-8 value on the Munsell color chart.
Claim 9
Dependent Claim
18 words
The method of claim 6 wherein the primer 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.
