Abstract:
Dye mixtures comprisingat least one dye of formula together with at least one dye from the group of formulae wherein the radicals have the definitions given in the claims, are suitable for dyeing or printing cellulose-containing fiber materials, while at the same time exhibiting good build-up behavior, and yield dyeings of deep shade having good fastness properties.
Abstract:
Dye mixtures, comprising at least one dye of formula and at least one dye from the group of formulae wherein the substituents are defined in the specification.
Abstract:
The present invention refers to dyestoffs of the formula I wherein Ar is a group of the formula II or of the formula III, D is a group of the formula IV, or of the formula V wherein the variables are defined as given in claim 1, processes for their preparation and their use for dyeing and printing hydroxy- and/or carboxamido-containing fiber materials.
Abstract:
Azo dyes comprising at least one structural unit of the formula (1) ##STR1## The azo dyes according to the invention are particularly suitable for dyeing cotton and wool and produce dyeings with good allround properties.
Abstract:
A dyestuff according to formula (I) ##STR1## or a salt thereof wherein the substituents have the definitions as defined in claim 1.The dyestuffs are useful for dyeing or printing nitrogen-containing or hydroxy-group-containing organic substrates and for the production of printing inks.
Abstract:
Dye mixtures comprising at least one dye of formulae ##STR1## wherein A is hydrogen or a substituent, R and R.sub.1 are hydrogen or C.sub.1 -C.sub.4 alkyl, X is halogen and L is an aliphatic linking group containing 1 to 12 carbon atoms, are suitable for dyeing cellulosic fiber materials.
Abstract:
Compounds of the formula ##STR1## in which the variables are as defined in the claims, which are suitable as fibre-reactive dyes for dyeing or printing widely varying fibre materials are described.
Abstract:
Dyestuffs corresponding to the general formula ##STR1## are described in which the variables have the meaning given in the specification. These dyestuffs have fiber-reactive properties and dye materials containing hydroxy and/or carboxamide groups, in particular fiber materials, such as wool, synthetic polyamide fibers and, in particular, cellulose fibers, such as cotton, in deep shades with good fastness properties.
Abstract:
Compounds of the formula X.sup.1 --B.sup.1 --D.sup.1 --N.dbd.N--K.sup.1 --Y--K.sup.2 --N.dbd.N--D.sup.2 --B.sup.2 --X.sup.2 (1) are suitable as reactive dyestuffs for the dyeing or printing of substrates.
Abstract:
Reactive dyes of the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl, X.sub.1 and X.sub.2 are halogen, B.sub.1 is an aromatic or aliphatic bridge member, or the radical of the formula --N(R.sub.2)--B.sub.1 --N(R.sub.3)-- is a piperazine radical, A.sub.1 is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan or dioxazine chromophore and, A.sub.2 is a radical of the formula ##STR2## in which D.sub.1 is substituted or unsubstituted phenyl or naphthyl, R.sub.5 and R.sub.6 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl, alk is substituted or unsubstituted C.sub.2 -C.sub.6 alkylene and Z is vinyl or a radical --CH.sub.2 --CH.sub.2 --U.sub.1, and U.sub.1 is a leaving group, and the radicals A.sub.1 and A.sub.2 differ from one another, are particularly suitable for dyeing or printing fibre materials containing hydroxyl groups or containing nitrogen. Dyeings with good fastness properties are obtained with a high tinctorial yield.
