摘要 1,158,044. Water-soluble dyestuffs. CASSELLA FARBWERKE MAINKUR A.G. 26 May, 1967 [27 May, 1966], No. 24680/67. Heading C4P. The invention comprises water-soluble dyestuffs containing at least one residue of the formula wherein "alk" is a C 2 -C 8 alkylene chain, Z is a vinyl group or a residue -CH 2 CH 2 X, wherein X is halogen, sulphate, phosphate, or a group containing a tertiary nitrogen atom, R 1 is hydrogen, halogen, hydroxy, alkyl, alkoxy, aryloxy, nitro or acylamino, R 2 is hydrogen or a sulphonic, carboxylic acid or sulphonamide group, m and n are 1 or 2 and m + n = 2 or 3, the dyestuffs containing at least one sulphonic, carboxylic acid or sulphonamide group and optionally containing further substituent atoms or groups. Preferred dyestuffs have the general formula wherein "alk", Z, R 1 , R 2 , m and n are as above, A is a pyrazol-5-one or an aromatic carbocyclic radical which may contain one or more alkyl, halogen, sulphonic acid, alkoxy, carboxylic, OH, amino or nitro groups. They are prepared by reacting a dyestuff or a dyestuff intermediate with a compound of the formula wherein "alk", R 1 , R 2 , Z, m and n are as above and B is -OH or -NH 2 and when an intermediate is used completing the formation of a dye in known manner. The examples describe the preparation of (i) azo dyes by diazotization and coupling, (ii) copper phthalocyanines by reacting a copper phthalocyanine sulphochloride with 4 - amino - 2 - sulphophenyl - ethyl - #- chloroethyl sulphone in pyridine and (iii) 1- amino - 4 - bromo - anthraquinone - 2 - sulphonic acid and p-aminophenylethyl-#-hydroxyethyl sulphone and copper chloride. Yellow, red, blue and turquoise shades are obtained on cotton materials.
