YELLOW AND MAGENTA DONOR FORMULATIONS FOR INCREASED RED VIVIDNESS

Yellow and magenta donor formulations that produce higher quality prints with fewer defects. The yellow and magenta formulas can be combined to form a red color representation with higher vividness and gamut.

MIXTURES OF REACTIVE DYES AND THEIR USE FOR THE DYING OR PRINTING FIBRE MATERIALS

A dye mixture comprising at least one dye of formula

##STR00001##

and at least one dye from the group of formulae

##STR00002##

wherein
(R.sub.1).sub.k denotes k identical or different substituents from the group C.sub.1-C.sub.4alkoxy, C.sub.1-C.sub.4alkyl and sulfo,
R.sub.2 is hydrogen or C.sub.1-C.sub.4alkyl,
R.sub.3 is hydrogen or C.sub.1-C.sub.4alkyl,
(R.sub.4).sub.n denotes n identical or different substituents from the group C.sub.1-C.sub.4alkoxy, C.sub.1-C.sub.4alkyl and sulfo,
(R.sub.5).sub.q denotes q identical or different substituents from the group C.sub.1-C.sub.4alkoxy and C.sub.1-C.sub.4alkyl,
X.sub.1, X.sub.2 and X.sub.3 are each independently of the others halogen, 3-carboxypyridin-1-yl or 3-carbamoylpyridin-1-yl,
T.sub.1 is a fibre-reactive radical of formula

##STR00003##

wherein
(R.sub.6).sub.0-2 denotes from 0 to 2 identical or different substituents from the group C.sub.1-C.sub.4alkyl, C.sub.1-C.sub.4alkoxy and sulfo,
Me means methyl, and Et means ethyl,
Z, Z.sub.1, Z.sub.2 and Z.sub.3 are each independently of the others vinyl or a radical CH.sub.2CH.sub.2U and U is a group removable under alkaline conditions,
M is hydrogen, an alkali metal or one equivalent of an alkaline earth metal,
k, n and q are each independently of the others the number 0, 1 or 2, and
l, m and s are each independently of the others the number 1 or 2,
are suitable especially for the dyeing or printing of cellulosic fibre materials, exhibit good build-up, and yield dyeings and prints having good reproducibility and good all-round fastness properties.

Mixtures of reactive dyes and their use in a method of di- or trichromatic dyeing or printing

A dye mixture, comprising at least one blue dyeing dye of the formula (1), wherein Q.sub.1 represents a bivalent radical of formula (4a), (4b) or (4c), wherein X.sub.1 denotes chlorine or fluorine, R.sub.1 is hydrogen or C.sub.1-C.sub.8 alkyl, R.sub.2 is hydrogen, C.sub.1-C.sub.8alkyl, C.sub.1-C.sub.4alkoxy or sulfo, Y.sub.1 is vinyl or a radical CH.sub.2CH.sub.2U and U is a leaving group removable under alkaline conditions, R.sub.3 is hydrogen or C.sub.1-C.sub.8alkyl that is unsubstituted or substituted by hydroxy, sulfo, sulfato, cyano, carboxy, C.sub.1-C.sub.4alkoxy or phenyl, r and s are each independently of the other the number 0 or 1, and t is the number 0, 1 or 2, and the sum of r, s and t is 2 or 3 and at least one yellow or red dyeing reactive dye is suitable especially for the dichromatic or trichromatic dyeing or printing of natural or synthetic polyamide fibre materials and yield dyeings or prints having good reproducibility and good all-round fastness properties. ##STR00001##
