Abstract: The invention concerns compounds of the general formula I where X is optionally substituted alkyl- or aryl-sulphonyl, Y is cyano, nitro, alkanoyl, aroyl, alkylsulphonyl, arylsulphonyl, carboxyl, carboxylic ester or optionally substituted carbamoyl, T is hydrogen, C1- to C4-alkyl, a radical which can be introduced by electrophilic substitution, or a radical of the formula -CH=T , where T is a radical of an active-methylene compound, and K is the radical of a coupling component. The compounds of the invention are very highly suitable for dyeing textile material, in particular polyesters.

Abstract: Dye mixtures based on red and yellow disperse dyes have a position in a colour area given by points with co-ordinates (x, y) (0.655, 0.344), (0.579, 0.341), (0.606, 0.314) and (0.690, 0.310); and a minimum luminous density factor beta > 0.25 0.40, based on measurements of (semi)synthetic materials treated with the mixture. Also claimed is a method of dyeing (semi)synthetic materials in a dyebath to which the dyes are added as a mixture or separately.

Abstract: Bis(5-azo-6-hydroxy-4-methyl-3-hydroxysulphonyl-pyrid-2-on- 1-yl) dyes (I) of formula (A), in the form of free acids or their salts, are claimed. In A, A and Y are each -SO3H; Z is D-N=N-; D is the residue of a diazo component; and X is a 2-8 C alkylene opt. with an ether O atom in the chain. Also claimed are bis(6-hydroxy-4-methy-3-hydroxysulphonyl-pyrid-2-on-1-yl) cpds. (II) of formula (A), in which Y is -SO3H and Z is H, in the form of the free acids or salts, and the prepn. of (II).
