摘要： 1,203,989. Monoazo pigments. SANDOZ Ltd. 19 Dec., 1967 [17 Jan., 1967; 26 Jan., 1967], No. 67698/67. Heading C4P. The invention comprises monoazo pigments of formula wherein D is the radical of an aromatic diazo component, E is the radical of a coupling component, R is H or a group of formula -C(X)NH 2 wherein X is 0, 5 or NH and n is 1 or 2, the pigments being free of COOH or SO 3 H groups. The pigments are prepared by the usual coupling reaction, preferred azo components being 2-hydroxy-naphthamides and acetoacetarylides. The pigments are yellow to red and may be used to colour textiles, paper and in the mass coloration of plastics e.g. polyvinylchloride.

摘要： Difficulty soluble azo pigments (I) are prepared by (i) diazotising an amine (II):- and coupling the diazo compound with a compound of the formula H-K, or (ii) reacting an amine (III) with an acid halide (IV), preferably the acid chloride, R1 is H, (substituted) hydrocarbyl or acyl, R2 is H, cyano, acyl or -CX-NH R1, K is a residue of the aromatic or heterocyclic series or a radical with the formula D-CO-CH-CO-NH-E,D is a (substituted) hydrocarbon residue which may also contain a hetero atom, E is a residue of aromatic character, Y is -CO- or -SO2-, X is O, S, Se or =NR1, and the rings A and B may carry other substituents, but not free carboxyl and sulphonic acid groups.

摘要： Sodium 1-amino-3-(dichloropyrimidylamino)-benzene-6-sulphonate is prepared by condensing 1, 3-diaminobenzene-6-sulphonic acid with 2,4,6-trichloropyrimidine in aqueous alkaline medium. Reference has been directed by the Comptroller to Specifications 851,537, 858,153, 885,814, 902,618, 916,094 and 924,933.ALSO:The invention comprises monoazo dyes of formula wherein A is a radical containing at least one substituent capable of reacting with fibres bearing hydroxyl and/or amino groups with formation of a chemical covalent linkage between the dyestuff and the fibre, R is a radical of the benzene, diphenyl or naphthalene series which may be further substituted, one X is hydrogen and the other X is -SO3H. The dyes are prepared by coupling the diazo compound of an amine A-NH-R-NH2 with a 1-hydroxynaphthalene-4,6- or -4,7-disulphonic acid or a mixture thereof or by reacting 1 mol. of a compound which is condensible with a primary amino group and bears at least one substituent as defined above, with 1 mol. of an aminoazo dye of formula or with 1 mol. of a mixture of the aminoazo dyes derived from 1-naphthol-4,6- and -4,7-disulphonic acids. Specified compounds containing reactive substituents include haloacetic, b -halopropionic, propiolic, acrylic, methacrylic, a - or b -monohalo- or a ,b -dihalo-acrylic, trihaloacrylic, crotonic, mono- and di-halocrotonic, maleic, mono- and di-halomaleic, fumaric, mono- and di-halofumaric and di-halosuccinic acids; cyanuric halides and their mono-condensation products with ammonia or amino, hydroxy or thiol compounds; di-, tri- and tetra-halopyrimidines. The substituent A may also be a diaryloxy-cyanuric, arylurethane, arylsulphonyloxyalkyl, HO.SO2.O-alkyl, epoxy or b -haloethyl radical. The dyes may be used to colour wool, silk, synthetic polyamide fibres, leather, and natural and regenerated cellulose fibres, by the usual procedures for reactive dyes, in red shades. Examples describe the preparation of the dyes. Reference has been directed by the Comptroller to Specifications 851,537, 858,183, 885,814, 902,618, 916,094 and 924,933.
