    Abstract: 2: 1 Chromium and cobalt complexes of general formula in which Me is chromium or cobalt, -A-N = N-B- is a radical of a dye of formula and -A1-N = N-B1- is a dye of formula above or any mono or disazo dye or azomethine dye which contains a metallizable o,o1-dihydroxy, o,o1-hydroxycarboxy or o,o1-hydroxyamino azo group and at least one water-solubilizing sulphonic acid and/or sulphonic acid amide group and in which R1 is a hydrogen atom or an alkyl group having 1-4 carbon atoms (which may be substituted), R2 is a hydrogen atom or an alkyl radical having 1-4 carbon atoms, R3 is a hydrogen atom, an alkyl radical of 1-4 carbon atoms, a nitro group, or acylamino group or a halogen atom and n is 1 or 2, are prepared preferably by reacting a dye of the formula above with a cobalt or chromium metallizing agent at 60-130 DEG C., 0.5-0.65 moles of cobalt or chromium metallizing agent preferably being used. An equimolar mixture of a 1: 1 chromium compound of an azo or azomethane dye and a dye of formula below may also be used to prepare the new complexes which provide grey, green and navy colours on natural and synthetic polyamides and cellulose.

    Abstract: 1 - (chlorosulphonylphenyl) - 4:5 - dihalogeno-pyridazones where the halogen is chlorine or bromine are made by sulphochlorinating a 1-phenyl - 4:5 - dihalogeno - pyridazone, made by condensing phenyl-hydrazine with mucochloric or mucobromic acid, or by reacting with phosphorus oxychloride or pentachloride or thionyl chloride a 1 - (sulphophenyl) - 4:5 - dihalogeno-pyridazone prepared by condensing a sulphophenyl hydrazine with mucochloric or mucobromic acid. 1 - (chlorocarbonylphenyl) - 4:5 - dihalogeno -pyridazones are made by treating with phosphorus oxychloride or pentachloride or thionyl chloride 1- (carboxyphenyl) - 4:5 - dihalogenopyridazone prepared by condensing a carboxyphenyhlydrazine with mucochloric or mucobromic acid. 1 - (chlorocarbonylalkyl) - 4:5 -dihalogenopyridazones are made by treating with phosphorus oxychloride or pentachloride or thionyl chloride 1 - (carboxyalkyl) - 4:5 - dihalogenopyridazones obtained by saponifying 1-(cyanoalkyl) - 4:5 - dihalogenopyridazones prepared by reacting the addition product of an a :b - unsaturated nitrile, such as acrylonitrile or methacrylonitrile, and hydrazine with mucochloric or mucobromic acid.ALSO:Dyes of the azo, anthraquinone and tetrazaporphin series are made by reacting a dye containing one or more acylatable amino groups with a compound of the formula where X is chlorine or bromine, A is a phenylene radical which may be substituted by alkyl, alkoxy, nitro or halogen or an alkylene radical of 1 to 4 carbon atoms which may be substituted, B is -SO2- or -CO- and Z is halogen. The invention also comprises dyes of the following general formulae and wherein Y is the radical of an anthraquinone dye, T is the radical of a tetrazaporphin dye, p is 0, 1, 2, 3 or 4, g is 1 or 2 (p+g) is not more than 6, D is the radical of an azo dye, A1 is an alkylene radical of 1 to 4 carbon atoms and A, B and X have the meanings given above. Dye radicals specified include those of monoazo and disazo dyes and metal complexes thereof, metal phthalocyanines and 1 : 4 - diamino - anthraquinone-2-sulphonic acid derivatives. Examples are given. The dyes dye and print cellulose materials in the presence of a basic-reacting substance and a heat-treatment and also dye and print wool, silk, leather, linear polyamides and polyurethanes and cellulose esters and ethers. Specification 924,660 is referred to.

    Abstract: Basic monoazo dyes having a cation of formula wherein X is a hydrogen atom or methyl radical and R is an alkyl or aralkyl group are prepared by decarboxylating a compound of formula by heating and alkylating the product. The dyes may be used to colour acrylonitrile polymers in orange and yellow shades. In examples: (1) the monoazo dye 3-amino-1,2,4-triazole-5-carboxylic acid- -->2-phenylindole is prepared and heated in dimethylformamide, and dimethylsulphate or benzyl chloride, is added to the mixture which is heated for several hours at 110 DEG -125 DEG C., cooled, diluted with ice water and salt added to precipitate the dye; (2) the monoazo dye 3-amino-1,2,4-triazole-5-carboxylic acid- --> 1-methyl-2-phenylindole is prepared, decarboxylated by heating in dilute aqueous hydrochloric acid, the decarboxylated dye separated, methylated with dimethyl sulphate and precipitated as the zinc chloride double salt. Specifications 787,891 and 837,471 are referred to.

    Abstract: 909,766. Disazo indole dyes. BADISCHE ANILIN-& SODA-FABRIK A.G. Jan. 2, 1961 [Jan, 2, 1960], No. 24/61. Class 2(4). The invention comprises dyes of formula where R is H or alkyl of 1 to 4 C atoms and R 1 is alkyl of 1 to 4 C atoms or aryl and A and B may contain substituents which do not dissociate in a neutral aqueous medium. The dyes are made by diazotising an appropriate amino-monoazo dye and coupling with the desired indole. Representative of specified values for R are methyl and butyl and for R 1 are ethyl, butyl and phenyl and the phenyl radical may contain substituents which do not dissociate in a neutral aqueous medium, e.g. methyl, and bromine groups. Examples of specified substituents for A and B are propyl, methoxy, chlorine, iodine, acetylamino and sulphonamido groups. Preferred dyes are of formula where R 1 is H, Cl, OMe or SO 2 NH 2 , R 2 is H or Me, R 3 and R 4 are H, Me. OMe and OEt and R 5 is Me or Ph. The dyes are used for colouring synthetic or semi-synthetic textile materials, e.g. cellulose 2¢ acetate, cellulose triacetate, polyurethanes, nylon and polyethylene terephthalate. The dyes are of especial use for colouring polyamides. Examples are provided of the preparation of the dyes and their use in colouring nylon, cellulose, triacetate, polycaprolactam and polyethylene terephthalate in yellow and red shades.
