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.

NOVEL POLYCYCLIC AROMATIC DYE COMPOUNDS ARE PROVIDED COMPRISING AT LEAST TWO MOIETIES IN CONJUGATE RELATIONSHIP AS PART OF A SINGLE CHROMOPHORE, EACH MOIETY COMPRISING THREE LINEARLY KATA CONDENSED SIX-MEMBERED AROMATIC RINGS WITH SOLUBILIZING GROUPS ATTACHED TO EACH MOIETY. AT LEAST ONE AUXOCHROMIC GROUP COMPRISING AN ATOM HAVING AN ATOMIC WEIGHT OF AT LEAST 31 IS BONDED TO THE CHROMOPHORE PORTION OF THE COMPOUND BY MEANS OF SAID ATOM.
摘要:
The invention comprises vat dyestuffs that contain at least one substituent imparting solubility in water, at least one aryl residue bound through an oxygen atom and two anthraquinone residues (including anthrone residues having four or more fused rings) which are joined together by an -NH-X-NH- bridge in which X is the residue of an organic di- or tri-basic acid. Examples include sulphonated bis-(aryloxyanthraquinonylamino)triazines and sulphonated bis - (anthraquinonylamino) derivatives of dicarboxylic acids such as oxalic, succinic, terephthalic, diphenyl-4: 41-dicarbo-oxylic and thiophene 2: 5-dicarboxylic acids. The dyes are made by sulphonation of an appropriate vat dye, by reacting a phenol or naphthol with a suitable halo- or nitro-vat dye or by acylating an aryloxyaminoanthraquinone with a di- or tribasic carboxylic acid and, if necessary, sulphonating the product, or by sulphating or acylating with an acylating agent containing a water-solubilizing group an appropriate vat dye containing a hydroxy group. The dyes dye cellulose ethers and esters, polyamides, polyacrylonitrile and polyurethane fibres, wool and silk but particularly cotton by the vat-dyeing process.
