    Abstract: The invention comprises dyes of formula:- where A is the residue of a phenol or a 1, 3-dihydroxybenzene. They are made by coupling, in an acid medium, 1 mol of diazotized 4-nitro-aniline with 1 mol of the naphthol component, 1 mol of the product being coupled in weak alkaline medium with 1 mol of tetrazotized 4, 41-diaminodiphenyl sulphide and 1 mol of an appropriate A component is allowed to couple with the disazo dye thus formed. Indicated for A are phenol, cresols, xylenols, resorcinol and 4-methyl-1, 3-dihydroxy-benzene. The dyes colour leather in green shades. An example is provided.

    Abstract: The invention comprises any ammonium salt derived from a 1 : 1 chromium complex of an azo or azomethine dye which contains a sulphonic acid group and a primary, secondary or tertiary amine whose nitrogen atom is substituted by an aliphatic radical containing at least one ether oxygen atom and which aliphatic radical may in turn have aromatic substitution. Among the amines specified for use in the process are 1-methoxy-3-aminopropane, 1 - benzyloxy - 2 - dimethylaminoethane, N - methylmorpholine and 1 - (b - ethyl - hexoxy) - 3 - aminopropane. Among processes described in examples are those in which the 1 : -chromium complex of the azo dye 6 - nitro - 2 - hydroxy - 1 - amino - naphthalene - 4 - sulphonic acid --> 2 - hydroxynaphthalene is boiled with 1-(b -ethyl-hexoxy)-3-aminopropane in aqueous ethanol; 4-nitro-2-aminophenol - 6 - sulphonic acid --> 1 - phenyl-3 - methyl pyrazolone - (5) is reacted with 1 - (b - ethyl - hexoxy) - 3 - aminopropane in aqueous formic acid and 4-nitro-2-aminophenol - 6 - sulphonic acid in aqueous solution is reacted with 2-hydroxy-5-nitrobenz-aldehyde; the product is boiled with aqueous chromium chloride and the product is reacted with 1 - (b - ethylhexoxy) - 3 - amino propane in aqueous acetic acid solution.

    Abstract: The invention comprises an ammonium salt of a 1 : 2 cobalt or 1 : 2 chromium complex of an azo dye and/or an azo methine dye and a primary, secondary or tertiary aliphatic amine whose nitrogen atom is substituted by an aliphatic radical which contains at least one ether oxygen atom. The ammonium salts are prepared by reacting appropriate complexes and amines. Representative of the many amines specified are 1-methoxy-3-aminopropane, 1 - benzyloxy - 2 - dimethylaminoethane, 1-(b -acetoxyethoxy) - 2 - diisopropylaminoethane and N-methylmorpholine. The metal complex dyes may be free from sulphonic acid groups or bear 1 to 4 such groups. Representative of the many azo dyes specified are 1-amino-2-hydroxy-4 - nitrobenzene --> 3 - methyl - 1 - phenylpyrazolone, 2-aminobenzoic acid --> 1-phenyl-3-methylpyrazolone, 1 - amino - 2 - hydroxybenzene - 4 - sulphamide --> 2 - hydroxynaphthalene, 1 - amino - 2 - hydroxybenzene - 5-sulphonethylamide --> acetoacetanilide and of the azomethine dyes those obtained from 4-nitro - 2 - aminophenol and 3,5 - dichlor - 2 -hydroxybenzaldehyde or 2-hydroxynaphthaldehyde. The products are soluble in organic solvents and or suitable for colouring nitrocellulose lacquers, anodized aluminium, cellulose ethers, polyester and polyamide resins and ester- and ketone-soluble vinyl chloride polymers. Examples are furnished.

    IPC: C09B67/12

    Abstract: Polyhalocopper phthalocyanines having high colour strength are obtained by heating a crude copper phthalocyanine pigment containing ten to sixteen halogen atoms at 60 DEG to 200 DEG C. in the presence of about 0.2 to 10 times the weight of an aromatic compound which is in liquid form under the conditions of treatment and is free from carboxylic and sulphonic groups and has an OH group attached to the nucleus, preferably in the presence of water. Specified aromatic compounds are phenols and naphthols. Specified phthalocyanines are polychloro and polychlorobromo copper phthalocyanines having ten to sixteen halogen atoms and mixtures of different polyhalo copper phthalocyanines. The treatment may be carried out in the presence of additional solvents which are inert under the reaction conditions and are not wholly miscible with water. Examples are given for treating polychloro- and polychlorobromo-phthalocyanine.

    Abstract: The invention comprises dyes of the general formula in which R1 denotes a hydrogen atom, an alkyl radical having 1 to 6 carbon atoms, an aralkyl radical or an aryl radical, R2 denotes a hydrogen atom or an alkyl radical having 1 to 6 carbon atoms, R3, R4, R5 and R6 denote hydrogen atoms or substituents which do not impart water solubility, Y denotes the radical of a coupling component free from sulphonic groups and X denotes the equivalent of an anion and a process for the preparation of basic azo dyes, wherein an aminophenyl-hydrazone of the general formula or a salt thereof having the general formula in which R1-R6 and X have the meanings given above is diazotized, coupled with a compound capable of coupling and, if desired, the product is treated with alkylating or aralkylating agents. X may be a Cl-, Br1HSO4-, H2PO4-, ZnCl3-, ZnBr3-, tosylate or CH3OSO3- ion R3-R6 may be alkyl, alkoxy or acyclamino radicals or halogen atoms. Representative of the coupling components specified are 1,3-dihydroxybenzene, 2-hydroxynaphthalene, 2-hydroxy - 8 - acetylaminonaphthalene, aminobenzenes substituted with such groups as 2-hydroxyethyl, cyanoethyl and hydroxyphenyl groups, 3-methyl, 1-phenyl-3-carbethoxy- and 1 - (2 - methylphenyl) - 3 - methylpyrazolones, hydroxyquinolines, imidazoles, 1,1,3 - trimethyl- and 2-methyl indolines and 2-phenylindole. Aminophenylhydrazones and their salts for use as starting materials are obtained by diazotizing aminonitro- or amino-acylaminobenzenes and coupling with methylene compounds of the general formula in which R1, R3 and R4 have the meanings given above, optionally treating the products with alkylating or aralkylating agents and converting the resulting nitro or acylamino compounds to the corresponding amino compounds by reduction or hydrolysis. Specified aminonitro- and aminoacylamino-benzenes include 1-amino-4-nitro- and 1 - amino - 2 - methoxy - 4 - nitro - benzenes, 1 - amino - 4 - formylamino-, -3- and -4-acetylamino-, -4-oxalylamino- and -2,5-dimethoxy -4- acetylaminobenzenes. Examples are furnished. The dyes are especially suitable for dyeing synthetic fibres, e.g. polyethylene terephthalate, polyhexahydroterephthalyl terephthalate, polyacrylonitrile and acrylonitrile-vinyl acetate copolymers.
