Abstract
Abstract The appearance of a heat-stable polymer coating is enhanced by a process which produces a decorative pattern within a coating produced by a heat-stable polymer coating composition. The process consists of applying a heat-stable polymer composition as a subsequent coat over or directly under an antioxidant composition which diffuses into the heat-stable polymer coating composition and renders the pattern visible, upon baking, within the baked coat produced by the coating composition.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
136 words
A process for preparing a decorative coating on a substrate, comprising the following steps, with (a) and (b) performed in any order: a. applying to a substrate a composition comprising 1. a heat-stable polymer; 2. a colorant; 3. optionally, an antioxidant; and 4. a liquid carrier; and b. applying to a substrate, in a decorative pattern, a composition comprising 1. an antioxidant; 2. a liquid carrier; and 3. optionally, one or more of a heat-unstable organic compound which decomposes to produce a colorant; and then heating the resulting coating to the heat-stable polymer fusion temperature wherein the heat stable polymer composition is stable at temperatures above 300° C and the heat-stable polymer is a silicone, polysulfide, polymerized p-hydroxy-benzoic acid, a polysulfone, a polyimide, a polyamide, a polysulfonate, a polysulfonamide, a fluorocarbon polymer, or a mixture thereof.
