Relevant articles and documents

Azo pyridone dyestuffs containing at least one reactive phosphoric or phosphonic acid group

Azo pyridone dyestuffs containing at least one reactive phosphoric or phosphonic acid group. The dyestuffs are characterized by the formula: wherein A is an aromatic radical containing at least one phosphoric or phosphonic acid group and R is a monovalent radical derived from a pyridone coupling component by removing a hydrogen atom attached to a ring carbon atom of the pyridone ring. The aromatic radical A is preferably a phenyl or naphthyl group. In addition to its phosphonic or phosphoric acid group or groups, radical A may be substituted with one or more halogen, alkyl, alkoxy, nitro, sulfonic acid or carboxylic acid groups. Cellulosic textiles, e.g., cotton or cotton/polyester blends, may be reactively dyed with these dyestuffs in an acid, neutral or alkaline bath using dicyandiamide or the equivalent. The phosphoric or phosphonic acid groups and the cellulosic material react to fix the dye through an ester linkage. Examples of suitable dyestuffs include those having the formula: STR1 and STR2

Water soluble cationic azo dyestuffs containing a cyclammonium group

A mixture of water soluble cationic azo dyestuffs devoid of carboxylic acid or sulphonic acid groups, each dyestuff in said mixture containing at least one cyclammonium group and said dyestuffs differing only in the constitution of the said cyclammonium group, said cyclammonium group being a gamma-picolinium group in one dyestuff and a beta-picolinium group in another dyestuff in said mixture, the water-solubility of said mixture being superior to that of the individual dyestuffs, the mixture being particularly useful for the coloration of polymers and copolymers of acrylonitrile.
