ABSTRACT:
A method is disclosed for producing a pigment coating on a substrate. A hardenable polymer coating is initially provided on the substrate, followed by an excess of hardening agent. This produces a first hardened coating with sufficient hardening agent remaining to harden a second polymer coating, containing suspended pigment, which is deposited on top of the first coating. The polymer is then pyrolyzed, leaving a coating of pigment on the substrate.
