DEFINITION

Classification: 427/504

Nonuniform or patterned coating (e.g., mask, printing, etc.):

(under subclass 496) Processes wherein the coating (1) is applied only to selected portions of a base (2) is applied in such a manner as to produce a coating of uneven, discontinuous, or nonuniform thickness, or (3) varies from area to area as to physical or chemical properties.
