DEFINITION

Classification: 204/484

Plural coating operations:

(under subclass 471) Process directed to the coating of a substrate with at least two layers and wherein at least one of the layers is applied electrophoretically or electro-osmotically.

(1) Note. A single step coating process wherein a previously coated object that is being coated (e.g., single step coating of an electrostatically sprayed object, etc.) is not considered to encompass plural coating operations for this subclass or the subclasses indented hereunder.
