DEFINITION

Classification: 8/550

ORGANIC ADDITIVE FOR DYE COMPOSITION, DYE COMPOSITION CONTAINING ORGANIC ADDITIVE, PROCESS OR PRODUCT; OTHER THAN EMULSIFIER, PH ADJUSTER OR STARCH OR GUM PRINT PASTE THICKENER:

(under the class definition) Subject matter involving organic dye additives (assistants) added to the dye to assist in or improve this dyeing.

(1) Note. Classification based on the following organic dye additives (assistants) is excluded from this subclass: (a)

materials used merely as emulsifiers, e.g., conventional detergents, wetting agents, dispersing agents, fatty acid salts (soaps), etc.; (b) ph adjusters, e.g., buffers, alkali, or acid, etc.; (c) starch or gum when used merely as a print paste thickener; (d) sugars as diluents or bulking agents in preparing dye powders.

(2) Note. Where an additive such as an emulsifier, etc. excluded above, is disclosed to have another function, classification on the additive in this subclass is proper.

(3) Note. Included herein are organic solvents, mordants, plasticizers, carriers, inhibitors, etc., which are used to assist in dyeing.

(4) Note. Sugars which are nonpolymeric are classified in subclass 611 regardless of functional moieties therein, e.g., a nitrogen containing sugar would not be in subclass 602 but in subclass 611.

(5) Note. An additive added to the substrate at a different time from the dye is also here, except if an additive is incorporated into the substrate material before forming the substrate, e.g., as in the production of a resin to be spun into a fiber, then the classification is not based on that additive which is considered part of the substrate.
