Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A composition consisting essentially of (a) 25-95%, based on the weight of total solids, of a heat-stable polymer, said heat-stable polymer being stable at temperatures above 300° C., which is silicone, polysulfide, polymerized parahydroxy benzoic acid, polysulfone, polyimide, polyamide, polysulfonate, polysulfonamide, or fluorocarbon polymers, or a mixture thereof; (b) colorant, which is carbon, carbonaceous residue, or a mixture thereof; (c) at least enough of an oxidation catalyst to promote oxidation under fabrication baking temperatures, said oxidation catalyst being a combination of compounds of both cerium and cobalt which decompose to oxides or hydroxides at temperatures in the range of 100°-500° C.; and (d) liquid carrier.
Claim 2
Dependent Claim
105 words
A composition consisting essentially of (a) 25-95%, based on the weight of total solids, of a heat-stable polymer, said heat-stable polymer being stable at temperatures above 300° C., which is silicone, polysulfide, polymerized parahydroxy benzoic acid, polysulfone, polyimide, polyamide, polysulfonate, polysulfonamide, or fluorocarbon polymers, or a mixture thereof; (b) colorant, which is carbon, carbonaceous residue, or a mixture thereof; (c) at least enough of an oxidation catalyst to promote oxidation under fabrication baking temperatures, said oxidation catalyst being a combination of compounds of both cerium and cobalt which decompose to oxides or hydroxides at temperatures in the range of 100°-500° C.; and (d) liquid carrier.
Claim 3
Dependent Claim
20 words
The composition of claim 1 wherein (b) includes 0.01-40%, based on the weight of the total solids, of carbon black.
Claim 4
Dependent Claim
11 words
The composition of claim 1 wherein the heat-stable polymer is fluorocarbon.
Claim 5
Dependent Claim
29 words

Acetate Octoate
Caprate Oleate
Caprylate Palmitate
Isodecanoate Ricinoleate
Linoleate Soyate
Naphthenate Stearate
Nitrate Tallate
______________________________________
