Abstract
Abstract A coating composition is described comprising a 1:2 chromium complex of a mono-AZO dye substituted with amino-phenol and coupled with 2-napthol in a thermosetting resin system. The composition when applied to a substrate imparts a super jet black coating which is non-bleeding, unaffected by the dispersion method or vehicle used, and is durable to the elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
69 words
A substrate material coated with a super jet black coating composition comprising a polymer component containing at least about 25% by weight of a thermosetting resin and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with amino-phenol and coupled with 2-napthol and, as the outer most layer, a transparent topcoat comprising a thermoplastic or thermosetting resin layer.
Claim 2
Dependent Claim
69 words
A substrate material coated with a super jet black coating composition comprising a polymer component containing at least about 25% by weight of a thermosetting resin and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with amino-phenol and coupled with 2-napthol and, as the outer most layer, a transparent topcoat comprising a thermoplastic or thermosetting resin layer.
Claim 3
Dependent Claim
25 words
The coated substrate material of claim 1 wherein the coating composition additionally contains, as the pigment component, up to about 95% by weight carbon black.
Claim 4
Dependent Claim
16 words
The coated substrate material substrate of claim 1 wherein the thermosetting resin is an acrylic resin.
Claim 5
Dependent Claim
32 words
The coated substrate material of claim 4 wherein the transparent topcoat layer contains iron oxide encapsulated mica particles in a particle to topcoat resin weight ratio of about 0.0001 to about 0.32.
Claim 6
Independent Claim
87 words
A method of coating a substrate comprising applying a super jet black coating composition comprising a polymer component containing at least about 25% by weight of a thermosetting resin and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with amino-phenol and coupled with 2-napthol to the substrate applying a transparent topcoat layer comprising a thermoplastic or thermosetting resin to the previously applied coating composition, and heating to cure the thermosetting resin and transparent topcoat layer.
Claim 7
Independent Claim
87 words
A method of coating a substrate comprising applying a super jet black coating composition comprising a polymer component containing at least about 25% by weight of a thermosetting resin and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with amino-phenol and coupled with 2-napthol to the substrate applying a transparent topcoat layer comprising a thermoplastic or thermosetting resin to the previously applied coating composition, and heating to cure the thermosetting resin and transparent topcoat layer.
Claim 8
Dependent Claim
23 words
