DEFINITION

Classification: 8/618

INORGANIC ADDITIVE FOR DYE COMPOSITION, DYE COMPOSITION CONTAINING INORGANIC ADDITIVE, PROCESS OR PRODUCT; OTHER THAN EMULSIFIER, PH ADJUSTER, WATER, NITROUS ACID FOR AZO COUPLING OR SULFUR DYE:

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

(1) Note. Classification based on the following Inorganic dye additives (assistants) is excluded from this subclass: (a) materials used merely as emulsifiers, e.g., conventional detergents, wetting agents, dispersing agents, Glauber's salt, etc. (b) pH adjusters, e.g., buffers, alkall, or acid, etc. (c) water; (d) nitrous acid for azo coupling; (e) sulfur reducing agent for vat or sulfur dye.

(2) 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, then the classification is not based on that additive which is considered part of the substrate.

(3) Note. A statement that a fiber is metal modified or incorporates a metal is assumed to mean a metal after treatment and thereby the metal is considered an assistant for this subclass.

(4) Note. Metallic compounds used for weighting and those

used for mordanting may be the same, the difference being only in the amount or agent incorporated.

(5) Note. Inorganic mordanting or weighting compositions are included herein.
