DEFINITION

Classification: 427/555

Nonuniform or patterned coating:

(under subclass 554) Processes wherein the coating utilized in the pretreatment of a substrate or the post-treatment of a coated substrate (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.
