WATER-SOLUBLE MONOAZOE DYE CONTAINING UREIDO GROUP AND FIBER REACTIVE SULFONYL GROUP AND ITS PRODUCTION AND USE

Document Type and Number:

Japanese Patent JPS63170464

Kind Code:

A

Abstract:

Water-soluble monoazo dyes of the general formula X - SO2 - A - N = N - W - @ - CO - NH - Z - SO2 - Y (1) wherein: X and Y are independently selected from vinyl, beta -thiosulfatoethyl, beta -bromoethyl, beta -acetyloxyethyl, beta -hydroxyethyl, beta -phosphatoethyl, beta -methylsulfonyloxyethyl, beta -phenoxyethyl, beta -sulfatoethyl, beta -chlorethyl, beta -phenylsulfonyloxy-ethyl and a group of the formula -CH2-CH2-NR<1>R<2>, in which R<1> and R<2> are independently selected from hydrogen, lower alkyl and sulfo-substituted lower alkyl; R is hydrogen, lower alkyl or sulfo-substituted lower alkyl; A is a phenylene or naphthylene radical optionally substituted with hydroxy, halogen, lower alkyl, lower alkoxy, carboxy or sulfo; W is a phenylene or naphthylene radical optionally substituted with carboxy, sulfo, amino, carbamoyl unsubstituted or substituted, sulfamoyl unsubstituted or substituted, lower alkyl, lower alkoxy, hydroxy or halogen; Z is a phenylene radical optionally substituted with halogen, lower alkoxy or lower alkyl; and the copper, chromium, cobalt and nickel metallized complex-dyes of said metal-free dyestuffs. These novel dyes yield on cellulose textiles dyeings with high tinctorial strength and purity of shade and with good light and wash fastnesses, particularly a good chlorine wash fastness. They are particularly useful in high temperature dyeing operations and can be prepared into stable aqueous solutions for use in continous dyeing operations. They provide a full range of shades and exhibit superior color yield and leveling in chemical pad steaming dyeing. They build strongly with superior fixation and have superior stability in acidic and alkaline environments.
