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 a 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: 4
Claim 1
Independent Claim
95 words
A super jet black coating composition particularly adapted for use as an automotive paint consisting essentially of a polymer component containing at least about 25% by weight of a thermosetting resin including a cross-linking agent, and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with aminophenol and coupled with 2-napthol, the composition so constituted that after coating on a substrate and the application of sufficient heat to cure the coating, a durable, super jet black composition with depth, clarity and non-bleeding blackness results.
Claim 2
Dependent Claim
95 words
A super jet black coating composition particularly adapted for use as an automotive paint consisting essentially of a polymer component containing at least about 25% by weight of a thermosetting resin including a cross-linking agent, and a pigment component containing at least about 5% by weight of a 1:2 chromium complex of a mono-AZO dye substituted with aminophenol and coupled with 2-napthol, the composition so constituted that after coating on a substrate and the application of sufficient heat to cure the coating, a durable, super jet black composition with depth, clarity and non-bleeding blackness results.
Claim 3
Dependent Claim
20 words
The composition of claim 1 which additionally contains, as the pigment component, up to about 95% by weight carbon black.
Claim 4
Dependent Claim
13 words
The composition of claim 1 wherein the thermosetting resin is an acrylic resin.
