Abstract

Dyes are made by coupling oleyl-H-acid with diazotized sulphanilic acid; by coupling 2 - methyl - 3 - methylbenzthiazole methyl sulphonic acid ester with p-aminobenzaldehyde and reacting the product with undecoyl chloride in the presence of pyridine, by acetylating 2 : 4-diaminophenol, condensing with stearic acid chloride, converting to the oxazole, and condensing the dimethylsulphate of the latter with veratric aldehyde; by reacting the condensation product of 6-aminoquinaldine dimethylsulphate and p-dimethylaminobenzaldehyde with undecoyl chloride in the presence of pyridine; by reacting the condensation product from 1 : 2 : 3 : 3 - tetramethyl - 5 - methoxyindolenium acetate and o-aminobenzaldehyde with capric acid chloride; by reacting the condensation product from 2-methylthiazolene dimethylsulphate and p-aminobenzaldehyde with undecylenic acid chloride; by reacting the condensation product from 2-methyl-6-dimethylaminobenzthiazole dimethylsulphate and p-aminobenzaldehyde with undecoyl chloride; by reacting the condensation product from 2 - methyl - 4 - phenylthiazole dimethylsulphate and 4-aminobenzaldehyde-3-sulphonic acid with ricinoleic acid chloride; by reacting the condensation product from 1-(31-amino-51-sulpho) - phenyl - 3 - methyl - 5 - pyrazolone and stearic acid chloride with p-dimethylaminoaniline in the presence of an oxidizing agent such as alkaline potassium ferricyanide; and by sulphonating the reaction product of 5-amino-a -naphthol with stearic acid chloride and coupling with p-diethylaminoaniline in the presence of an oxidizing agent. The dyestuff of formula <FORM:0481274/IV/1> may be prepared by the method described in Specification 396,646.
