Abstract: Chromium complex dyes are disclosed which have the formula ##STR1## wherein S.sub.1 represents a hydrogen or halogen atom, a nitro group, a sulpho group, an alkyl or alkoxy radical, an acylamino or arylazo group,S.sub.2 represents a hydrogen or halogen atom, a nitro group, a sulpho group, an alkyl or alkoxy radical,S.sub.3 represents a hydrogen atom, a nitro group or a halogen atom,P is 1 or 2,R represents a fluorochloropyrimidyl or fluorotriazinyl radical, a chloroacetyl, bromoacetyl, .alpha.-chloro- or .alpha.-bromoacryloyl radical or an .alpha.,.beta.-dichloro- or .alpha., .beta.-dibromopropionyl radical, andM.sup..sym. represents a cation.

Abstract: Monoazo compounds of the formula ##STR1## wherein Y is phenyl, or phenyl substituted by Z--NH--, sulfo, chloro or methyl; andZ is .alpha.,.beta.-dibromopropionyl or .alpha.-bromoacryloyl, are excellent dyes and are suitable for dyeing and printing materials of the most diverse kind.

Abstract: Heavy metal complexes of azo dyes of the formula ##STR1## wherein D is the radical of a diazo component of the benzene or naphthalene series that carries the group --[CO].sub.p-1 OH in ortho-position to the azo group, p is 1 or 2, X.sub.1 is an unsubstituted or substituted amino, alkoxy, aryloxy, alkylmercapto, arylmercapto or aralkoxy group, X.sub.2 is an unsubstituted or substituted amino group or a low molecular alkyl radical, X.sub.3 is an unsubstituted or substituted amino group and Y is a cyano or carbonamido group, said azo dyes of the formula (1) containing at least one of the following groups: a sulpho or sulphonamido group, a sulphonamido group which is substituted by low molecular alkyl, phenyl or phenyl which carries non-ionogenic substituents, a low molecular alkylsulphonyl group or a phenylsulphonyl group which is unsubstituted or substituted by non-ionogenic substituents.

Abstract: A process is described for the manufacture of chromium complexes of metallizable dyes in the form of solid dyestuff powders of low salt to salt-free content, or of concentrated solutions of low salt or salt-free content in which a metallizable dye, or a mixture of metallizable dyes, in an organic solvent which is immiscible or sparingly miscible with water, or reacted with a chromium compound, in the course of which any water which is liberated is removed by azeotropic distillation, and the resulting chromium complex, provided it is a 1:1 complex, is then optionally reacted in the presence of a base with a further mol of a metallizable dye, or of a colorless, complexforming compound, then isolated from undissolved constituents, and the resulting dye solution of low salt or salt-free content is optionally concentrated or evaporated to dryness, whereby it is possible the manufacture of 1:1 or 1:2 chromium complexes without the handicap of effluent pollution, and to isolate the dyes without using salt.

Abstract: Water-soluble azo dyes of the formula WHEREIN Y is a fiber-reactive group, n is 1 or 2, m is 0, 1 or 2 and the benzene rings A and B may be further substituted are disclosed. They are useful for dyeing nitrogen-containing fibers and cellulose materials and are distinguished by very bright and brilliant shades, possessing good stability, fastness to light, wet processing and fixation.

Abstract: Chromium complex dyes of the formula ##SPC1##Wherein one of the symbols X.sub.1, X.sub.2 and X.sub.3 is hydrogen and each of the others is hydrogen, a halogen atom, a nitro group, a methyl or a methoxy group, R is a phenyl radical which is optionally substituted by halogen, low molecular alkoxy, alkyl or nitro and Me.sup.+ is a cation are disclosed; said dyes being useful in dyeing synthetic and natural polyamides to produce dyeings which are level and have good fastness to light, washing, fulling, decatizing and carbonizing.
