    • 4-Allylmercapto-benzoic acid is made by reacting 4-mercapto-benzoic acid with allyl chloride. 4-Allylsulphonyl-benzoic acid is made by oxidising with hydrogen peroxide 4-allylmercapto-benzoic acid. 2- (41- Allylsulphonyl-phenyl)-benzthiazole- 6-carboxylic acid is made by condensing 5-carboxy-2-amino-thiophenol hydrochloride with 4-allylsulphonyl-benzoyl chloride. The acid chlorides of the above acids are made by reacting the acids with thionyl chloride.ALSO:The invention comprises vat dyes which contain at least one allylmercapto or allylsulphonyl group bound to a carbon atom of the vat dye. The dyes are made by reacting a vat dye containing an exchangeable halogen atom with allyl mercaptan or with an amine containing an allyl-mercapto or allylsulphonyl group, by etherifying a vat dye containing a mercapto group with an allyl halide, by reacting a vat dye containing an acylatable amino group or an amino-anthraquinone with an acylating agent containing an allylmercapto or allylsulphonyl group when the starting amine does not contain such a group, by carbazolizing allylmercapto- or allylsulphonyl - anthrimides, by ring - closing allylmercapto- or allylsulphonyl-dianthraquinone-carboxylic acid hydrazides to form dianthraquinonyl-oxdiazoles, by ring-closing o-carboxy - arylamino - allylmercapto - anthraquinones or allylsulphonyl-1-arylaminoanthraquinone - 2 - carboxylic acids to form acridones or by condensing 1-amino-2-bromo-allylmercapto - anthraquinones or 2 - amino - 1 -chloro - allylsulphonyl - anthraquinones to form indanthrones. Examples describe vat dyes of the aroylamino-anthraquinone, anthraquinonyl-triazine, dianthraquinonyl-oxdiazole, anthraquinone - thiazoyl - anthraquinone, anthrimide-carbazole, anthanthrone and acedianthrone series. The dyes vat-dye and print natural or regenerated cellulose textile materials. 4: 10 - Dimercapto - anthanthrone is made by heating 4: 10-dibromo-anthanthrone with sodium hydrosulphide. 1 - Amino - 6 - allylmercapto - anthraquinone is made by reacting the sodium salt of 1-amino-6-mercapto-anthraquinone with allyl chloride.
