Abstract
This invention is directed to new water-soluble, monoazo dyes having the following general formula: ##STR1## in which: X and Y are independently selected from the group consisting of: ##STR2## R, R.sub.1, R.sub.2 are independently selected from H, lower alkyl of one to four carbons and sulfonated lower alkyl; PA0 A is a phenyl or napthyl radical optionally substituted with halogen, hydroxy, lower alkyl, lower alkoxy, carboxylic acid or sulfonic acid; PA0 W is a phenyl or naphthyl radical optionally substituted by carboxylic acid, sulfonic acid, amino, amido, lower alkyl, lower alkoxy, hydroxy or halogen groups; PA0 Z is a phenyl radical optionally substituted with halogen, lower alkoxy or lower alkyl groups; and copper, chromium, cobalt and nickel metallized complexes of said dyestuffs. The dyes of this invention on cellulose textiles have high tinctorial strength, purity of shade, light and wash fastness particularly chlorine wash fastness. They are particularly useful in high temperature dyeing operations and can be prepared into stable aqueous solutions for use in continuous dyeing operations. The dyes of this invention provide a full range of shades and exhibit superior color y…
