DEFINITION

Classification: 427/249.9

Patterned or non-uniform coating:

(under subclass 249.8) Process which includes forming the diamond coating wherein the coating is applied (a) only to selected portions of a base, (b) in such a manner as to produce a coating of non-uniform thickness, (c) to limited areas only on a base by covering the other areas, or (d) such that it varies from area to area as to chemical or physical properties.

(1) Note. This subclass provides for a process wherein a stencil may be temporarily adhered to a base during the step of applying the coating.

(2) Note. This subclass provides for a process wherein a discontinuous cover is applied to a base and a different coating material is then applied to the base through the discontinuities.

(3) Note. This subclass provides for a process wherein a patterned coating may be applied to selected areas or an entire base may be coated with a pattern forming composition; in the latter case, selected portions of the coating, once formed, may be removed.
