DEFINITION

Classification: 530/224

(under subclass 210) Processes wherein salts of rosin acids are formed using a metal containing material, or products of such processes.

(1) Note. Metal salts of mixed naturally occurring resin (rosin) acids, also referred to as rosin soaps or metal resinates, are included in this and the indented subclass 225.

(2) Note. The production of a pure rosin acid derivative of known chemical structure from rosin or its derivative is classified in the class and subclass providing for the compound produced.

(3) Note. Compositions comprising a metal resinate and another component, such as water, excess alkali, etc., and having a known utility are classified in the appropriate

composition class.
