DEFINITION

Classification: 204/499

Cathodic processes only:

(under subclass 489) Process in which the bath composition is specifically directed to use in cathodic processes only (i.e., cationic compositions).

(1) Note. Processes involving compositions which are suitable for both anodic and cathodic processes are excluded from this subclass and the subclasses indented hereunder.
