Abstract: Compound of the formula ##STR1## in which both groups --NR.sub.1 R.sub.2 are identical;R.sub.1 is C.sub.2-4 alkyl, substituted by one or two hydroxy groups and salts thereof,R.sub.2 is hydrogen, C.sub.2-4 hydroxyalkyl or --CH.sub.2 CH.sub.2 CN, provided that when R.sub.2 is --CH.sub.2 CH.sub.2 CN then R.sub.1 can only be --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OH,and mixtures of such compounds, which compounds are in free acid or salt form, and are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, especially leather and textiles containing or consisting of natural or synthetic polyamides or of natural or regenerated cellulose; the most preferred substrate is textile material containing or consisting of cotton.

Abstract: The present invention provides compounds of the formula, ##STR1## in which both groups --NR.sub.1 R.sub.2 are identical; R.sub.1 is C.sub.2-4 alkyl, substituted by one or two hydroxy groups or by one --OR.sub.3 groups, where R.sub.3 is C.sub.1-4 alkyl or C.sub.2-4 hydroxyalkyl, andR.sub.2 is hydrogen, C.sub.2-4 hydroxyalkyl or --CH.sub.2 CH.sub.2 CN, provided that when R.sub.2 is --CH.sub.2 CH.sub.2 CN then R.sub.1 can only be --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 OH,and mixtures of such compounds, which compounds are in free acid or salt form, and are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, especially leather and textiles containing or consisting of natural or synthetic polyamides or of natural or regenerated cellulose; the most preferred substrate is textile material containing or consisting of cotton.

Abstract: Azo dyes of the formula ##STR1## wherein X represents a direct bond or a divalent radical,Y represents a direct bond, an alkylene radical, --S--, --O--, --NH--CO--NH-- or --CH=CH--,R represents a hydrogen atom or a hydrocarbon radical andK represents a primary, secondary or tertiary amino group or an ammonium, hydrazinium or a cycloimmonium group which are useful for dyeing fibers and textiles of polyacrylonitrile or acrylonitrile copolymers and for the dyeing of paper.

Abstract: Disclosed are phthalocyanine dyes of formula ##STR1## IN WHICH Me signifies copper or nickelPc signifies a phthalocyanine radical,The R.sub.1 's, independently, signify a linear, branched or cyclic aliphatic radical, unsubstituted or substituted by chlorine, bromine, alkoxy, cyano, alkylcarbonyl, alkoxycarbonyl, benzoyl, alkylcarbonyloxy, alkoxycarbonyloxy or benzoyloxy,The R.sub.2 's, independently, signify a phenyl radical, unsubstituted or substituted by a chlorine or bromine atom or a nitro or cyano group or by up to two substituents selected from methyl, methoxy and ethoxy groups,m signifies 1 or 2, andn signifies 2 or 3,The sum n + m being 3 or 4And mixtures thereof, their production and use particularly in the dyeing of paper and plastics and in the production of surface coating media such as inks and lacquers.
