-
, (2008/06/13)
A dyestuff of the formula STR1 in which R is H or Ch3 STR2 in which R1 is H, substituted or unsubstituted C1 -C4 -alkyl or --X--Y X is a divalent aliphatic, cycloaliphatic, aliphaticcycloaliphatic radical or an araliphatic radical Y is COOH, SO3 H, OSO3 H or SO2 G, in which G is CH=CH2 or --CH2 --CH2 --Z, in which Z denotes a group which can be eliminated under alkaline conditions, R2 is H or C1 -C4 -alkyl, and the benzene radical D and the benzene or naphthalene radical L can contain customary substituents, is suitable for the dyeing and printing of OH- and NH-containing materials. They produce lightfast and wetfast brilliant dyeings and prints.

A reactive dye of the formula STR1 in which: F is a radical selected from the group consisting of metal-free or metal-containing monoazo or disazo dyes containing at least one --SO3 H group, anthraquinone dyes, sulfophthalocyanine dyes, formazan dyes, phenazine dyes, oxazine dyes and nitroaryl dyes, R is hydrogen, C1 -C4 alkyl which is unsubstituted or substituted with --COOH or --SO3 H, cyanoethyl, or hydroxyethyl, X is fluorine, chlorine, bromine, --SO3 H, phenylsulfonyl or C1 -C4 -alkylsulfonyl, p is 1 or 2 and A is a radical of the formula STR2 in which: Y is chlorine, bromine, fluorine, --OH, --OSO3 H, --O-acyl, --CN, --COOH, --COO--C1 -C4 -alkyl, --CONH2 or --SO2 --Z, the group designated "alk" is a straight or branched polymethylene radical having 2 to 6 carbon atoms, V is STR3 hydrogen or C1 -C4 -alkyl which is unsubstituted or substituted by C1 -C2 -alkoxy, carboxyl, sulfo, halogen or hydroxy, Z is β-halogenoethyl, vinyl or β-acetoxyethyl, or A is a radical of the formulae STR4 in all of which R' is C1-6 -alkyl or hydrogen, Z is as defined above, o is 0 to 6, and m is 2 to 6.
Barium laked phenylazonaphthalene dye containing sulfonic acid groups
-
, (2008/06/13)
Azo dyes containing sulfonic acid groups laked with barium and derived from an anilinesulfonic acid as diazo component and a β-naphtholsulfonic acid as coupling component for example a dye of the formula STR1 The dyes are eminently suitable as pigments for coloring surface coating compositions, printing inks and particlarly resins.
