Suitable as acid dyestuffs for the dyeing of wool, silk and polyamides in mainly golden-yellow to orange shades have general formula:- (where D1 is an aromatic or heterocyclic residue, R is H or lower alkyl, X is the residue of a reactive compound or the residue of an alpha, beta-unsaturated aliphatic carboxylic acid or a vinylsulphone group. The group X- -D1 contains at least one -SO3H or -COOH group. In an example, 173(wt) aniline-o-SO3H were dissolved in 4000 pts water and diazotised in the usual way with sodium nitrite and conc. HCl. The diazo suspension was then added to a suspension of 150 pts. 2,6-di-hydroxy-3-cyano-4-methylpyridine in alkaline solution. After stirring for 4/6 hours the product was filtered off, washed and dried to yield a yellow powder which dyed wool and polyamides in yellow shades from an acid dyebath.

Anthraquinone-azo compounds, their preparation and their use as dyestuffs

The invention provides water- soluble anthraquinone-azo dyestuffs of the general formula <IMAGE> in which R1 represents a hydrogen atom or a sulphonic acid group, and the two R1s are not both hydrogen, K represents the radical of a coupling component and Z represents a fibre- reactive group which is linked to a carbocyclic aromatic nucleus of the coupling component, n being 1 or 2. The compounds may also be in the form of their salts. The compounds, preferably in the form of alkali metal salts, are useful for dyeing and printing fibre materials containing carboxamide groups, e.g. silk, wool and other animal hairs, polyamide and polyurethane fibres, and fibre materials containing hydroxy groups, e.g. cotton, linen and viscose rayon. Green to olive-green, blue and grey dyeings are obtained having good fastness to wet processing and very good fastness to light. The invention also provides intermediates for these dyestuffs in which the Zn group is replaced by an NHR group in which R represents a hydrogen atom or a lower alkyl group or a cyano-lower alkyl group.
