摘要： 1422078 Disazo pigments HOECHST AG 6 June 1974 [6 June 1973] 25128/74 Heading C4P Novel disazo pigments of formula (where each R, which may be the same or different, is H, halogen, methyl or methoxy and each X, which may be the same or different, is H or halogen) are prepared by diazotizing the corresponding 2,7-diamine-diphenylenesulphone and coupling, optionally in the presence of organic solvents, with the appropriate 5- acetoacetylamino-benzimidazolone or a mixture of two such benzimidazolones. After preparation the pigments are preferably heated in an organic solvent such as ethanol, o-dichlorobenzene or dimethylformamide to modify their crystal form. The pigments are used for printing inks, colour lakes and dispersion paints and for colouring rubber, plastics and natural and synthetic resins. They are also used for pigment printing especially on textile fibres and paper.

摘要： Novel valuable, water-insoluble disazo pigments of the general formula 1 WHEREIN R is hydrogen, methyl, methoxy or halogen, preferably chlorine or bromine, and X also represents hydrogen or halogen, preferably chlorine. The disazo compounds are obtained by bisdiazotizing a 2,7-diaminodiphenylenesulfone and coupling it on an acetoacetylbenzimidazolone. These pigments are suitable for preparing printing inks, color lakes and dispersion paints, for dyeing rubber, plastics and natural or synthetic resins. Furthermore, they are suitable for the printing of pigments on substrates, especially textile fibre materials or other flat articles such as paper.

摘要： The invention comprises azo dyestuffs of the general formula wherein A is an aromatic-carbocyclic or -heterocyclic radical or a copper phthalo-cyanine residue (Cu-Pc), R is H, alkyl, aralkyl, aryl, or carboxylic acid ester radical, R1 is C2-C10 straight or branched chain alkylene radical which may be substituted, R2 is H or C1-C4 alkyl radical, R3 is C1-C4 alkyl or alkenyl radical, n is 1 or 2 and when A is CuPc n is 1, 2, 3 or 4. R1, which is preferably ethylene or propylene, may be substituted by aryl, cycloalkyl, ether, thioether or halogen and A is preferably a benzene, naphthalene, thiazole, benzothiazole, imidazole or benzimidazole radical which may be substituted by sulphonic or carboxylic acid groups, sulphonamide, sulphone, carboxylic acid ester, nitro, substituted or acylated amino groups, cyano, halogen, trifluoromethyl, alkyl, alkoxy, cyanoalkyl, cyanalkoxy or further azo groups. They are prepared by (a) diazotizing an appropriate aromatic-carbocyclic or heterocyclic or CuPc diazo compound with an appropriate pyrazolone coupling component or (b) reacting an appropriate azo dye containing an -R1-OH group in the 1-pyrazolone position with a compound OCN-CH(R2)-OR3 in an organic solvent which is inert to isocyanates. The dyes give yellow, orange, red and green shades on wool, silk, leather and synthetic polyamides, natural or regenerated cellulose at elevated temperatures.
