DEFINITION

Classification: 427/402

(under the class definition) Processes which include applying a plurality of dissimilar coating materials in superposed relationship on a base or applying diverse coating material to the coating on a previously coated base.

(1) Note. Coatings which contain essentially the same ingredients, but in different proportions are considered to

be different coating materials.

(2) Note. Impregnation is considered coating even where a distinct surface coat is not formed.

(3) Note. Processes for applying several coats or layers of the same material are not provided for here and are classified in appropriate subclasses elsewhere in this class.

(4) Note. Processes of applying a different coating to a previously coated article are classified in this and the indented subclasses as processes of applying different coatings.

196, 201 and 202+, for applying plural coats where at least one is particles or fibers.

214, for applying plural coats or particles.

258+, for applying plural coats where at least one is nonuniform.
