Appeal No. 1997-3093
Application 08/415,384
THE INVENTION
Appellants claim a process for making polymer powders for
use in coating cores to form developer compositions used in
electrostatographic or electrophotographic imaging systems,
especially xerographic imaging and printing processes
(specification, pages 1-2). Claim 1 is illustrative and reads
as follows:
1. A process for the preparation of carrier powder
polymer coatings consisting of the supercritical
polymerization of two monomers and surfactant in a
supercritical medium, and wherein the surfactant forms a layer
on the polymer product and which surfactant layer is of a
thickness of from about 0.05 to about 1.5 microns, and the
powder polymer carrier coating is of a size of 0.05 to about 5
microns.
