DEFINITION

Classification: 204/492

Anodic processes only:

(under subclass 489) Processes in which the bath composition is specifically directed to use in anodic processes only (i.e., anionic 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.
