Dyestuffs having the general formula: ##STR1## wherein Z.sup.1 and Z.sup.2 each independently represent oxygen or ##STR2## in which Y is hydrogen, an optionally substituted hydrocarbon radical or an acyl radical,

Substituted 2,7-dioxo-2,7-dihydrobenzo[1:2-b; 5:6-b.sup.1 ]difuran or

A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-hydroxy-2-(optionally substituted) lower alkyl-4-anilinoanthraquinone optionally having from 1 to 3 substituents in the anilino nucleus. Preferably the latter carries a single substituent ortho to the --NH--group.

Transfer dyeing with 1-hydroxy-2-alkyl-4-anilino anthraquinone dyes

A process for the transfer color printing of synthetic textile materials wherein the dyestuff used is a 1-amino-4-anilinoanthraquinone having one or two ortho substituents in the anilino group. The anthraquinone nucleus may be further substituted in the 2- and/or 3-position, preferably by an electron-withdrawing group in the 2-position.

Transfer dyeing with 1-amino-4-anilinoanthraquinone dyes

Substituted 2,6-dioxo-2,6-dihydrobenzo[1:2-b, 4:5-b']difurans or -dipyrroles and processes for their manufacture. The compounds are dyestuffs which are particularly useful in the form of aqueous dispersions for application to polyester textile materials.

Benzodipyrrole dyestuffs

Substituted 2,6-dioxo-2,6-dihydrobenzo[1:2-b, 4:5-b.sup.1 ]difurans or -dipyrroles and processes for their manufacture. The compounds are dyestuffs which are particularly useful in the form of aqueous dispersions for application to polyester textile materials.

Benzodifuran dyestuffs

A process to color aromatic polyester textiles navy blue to black by dyeing, padding or printing with an aqueous dispersion of mixtures of four specified azo and anthraquinone disperse dyes.

Disperse dyestuff mixtures

A process to color in blue to black shades aromatic polyester textile materials by dyeing, padding or printing an aqueous dispersion of a dyestuff mixture of three or four specific azo and anthraquinone disperse dyes.

Dyeing nylon by applying sulphonated or unsulphonated dyestuffs containing cyclic anhydride groups, anhydride forming dicarboxylic acid groups or half-esters or half-amides thereof, as free acids or as salts with ammonia or volatile amines, and heating the fibre until dyestuff fixation takes place.

Dyeing process

The disperse monoazo dyestuffs, free from sulphonic acid groups, which are represented by the formula: ##SPC1## Wherein X is alkyl, substituted alkyl, phenyl or optionally substituted carbamoyl; Y is a hydrogen atom or a substituent; and Z is a hydrogen atom or an optionally substituted alkyl, cycloalkyl, aryl or heterocyclic radical or an optionally substituted amino group, a process for the manufacture of the said dyestuffs and their use for coloring synthetic textile materials.

Monoazo compounds derived from 2-hydroxymethyl-amino benzoic acids and

Dyeing cellulose or cellulose/polyester blends by applying unsulphonated dyestuffs containing cyclic anhydride groups, anhydride-forming dicarboxylic acid groups or half-esters or half-amides thereof, as free acids or as salts with ammonia or volatile amines, and heating the fibre until dyestuff fixation takes place.
