DEFINITION

Classification: 205/80

Electrolytic coating (process, composition and method of preparing composition):

(under the class definition) Process directed to the formation or deposition by an electrolytic action of a permanent coating material or materials upon a base, electrolyte compositions therefor and methods of making said electrolyte compositions.

(1) Note. It is intended by the phrase "permanent coating" to include those coatings which remain part of the finished article as distinguished from those coatings which are

stripped from a base as provided for in subclass 67, and indented subclasses.
