Abstract: Valuable dyestuff formulations for dyeing polyester fibres are obtained without expensive finishing techniques by simple mixing of emulsifiers with dyestuffs of the formula ##STR1## wherein A=alkylene,B and D=a direct bond or a bridge member,V and Q=hydrogen, alkyl, alkenyl, cycloalkyl, aralkyl, aryl or acyl,X and Y=a non-ionic substituent,m and n=0 to 3 andp and r=0 to 10, with the proviso that p represents 3-10 if r=0 or 1 and D=a direct bond.The dyeing formulations are present in the liquid or dissolved form under the dyeing conditions. The use of dispersing agents, protective colloids, levelling agents and carriers is thus superfluous.

Abstract: Concentrated solutions of a direct dye having, in the free acid form the formula: ##STR1## are described. The solutions contain 10-30% (by weight) of the dye, 5-20% of one or more specifically defined bases; 0-5% of alkali metal cations; and 45-85% water and have a lower viscosity and solvent to dye ratio than solutions of the dye of similar strength prepared according to prior art methods. The solutions are prepared by isolating the diazonium salt of p- (p-aminophenyl)azo benzenesulfonic acid then coupling the diazo into J-Acid.

Abstract: Dyes of the formula ##STR1## wherein B and D are each independently 1,4-phenylene or 1,4-naphthylene; M is hydrogen, lithium, sodium, potassium or ammonium;A.sub.1 is hydrogen, C.sub.1-4 alkoxy, C.sub.1-4 alkyl, trifluoromethyl, nitro, chloro, bromo, cyano, or hydroxy;B.sub.1 and B.sub.2 are each hydrogen, C.sub.1-3 alkoxy, C.sub.1-3 alkyl, chloro or bromo;D.sub.1 is hydrogen, C.sub.1-4 alkoxy, C.sub.1-4 alkyl, or chloro;D.sub.2 is hydrogen, C.sub.1-4 alkoxy, C.sub.1-4 alkyl, chloro, bromo, fluoro, or acylamino, acyl being C.sub.1-5 alkanoyl, C.sub.1-5 alkylsulfonyl, benzoyl or benzenesulfonyl, each acyl unsubstituted or substituted with 1 to 3 of C.sub.1-2 alkyl, C.sub.1-2 alkoxy, chloro, bromo, cyano, or hydroxy; andR.sub.1 and R.sub.2 are each C.sub.1-6 alkyl, C.sub.1-6 chloro or bromoalkyl, C.sub.2-6 hydroxy- or dihydroxyalkyl, C.sub.2-6 alkoxyalkyl, C.sub.1-6 cyanoalkyl, or phenyl-C.sub.1-2 alkyl (phenyl unsubstituted or substituted with 1 to 3 of C.sub.1-2 alkyl, C.sub.

Abstract: New yellow mono-azo dyes which are insoluble in water are disclosed. The dyes are derived from 1-phenyl-3-aminopyrazoles and are particularly effective in dyeing synthetic hydrophobic fibers to intense yellow shades.

Abstract: Water-insoluble azo dyestuffs corresponding to the formula: ##STR1## in which X represents halogen, cyano, nitro, alkyl, polyfluoroalkyl, polyfluoroalkoxy, alkylsulphonyl, sulphonamido, or sulphonamido substituted by one or two alkyl groups;Y and Z are the same or different and represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, polyfluoroalkyl, polyfluoroalkoxy, alkylsulphonyl, sulphonamido or sulphonamidosubstituted by one or two alkyl groups;R represents hydrogen, halogen, cyano, nitro, alkyl, alkoxy, polyfluoroalkyl, polyfluoroalkoxy, alkylsulphonyl, sulphonamido, or sulphonamido substituted by one or two alkyl groups;m is equal to 0 or 1;and the nucleus A may be substituted by one or more chlorine atoms or alkyl, alkoxy or acylamino groups.These dyestuffs may be used for dyeing synthetic or artificial textile fibers, especially polyester fibers.
