WHEREIN D AS THE REST OF A DIAZO COMPONENT IS NITROPHENYLENE, CHLOROPHENYLENE, NITRO-CYANO-PHENYLENE, NITROCHLORO-PHENYLENE, NITROFLUOROMETHYL-PHENYLENE, DINITRO-TRIFLUORO-METHYL-PHENYLENE - DINITRO-CHLORO-PHENYLENE OR NITRO-DICHLORO-PHENYLENE, Y IS HYDROGEN, LOWER ALKYL, LOWER ALKOXY OR ACETYLAMINO, Z IS HYDROGEN, LOWER ALKYL OR LOWER ALKOXY AND R IS HYDROGEN OR LOWER ALKYL. THE DYESTUFFS ARE DISTINGUISHED BY A GOOD COLOR BUILD-UP AND ARE SUITABLE FOR DYEING AND PRINTING POLYESTER AND POLYESTER-CONTAINING FIBERS FAST TO LIGHT, WASHING AND THERMOFIXATION.
摘要:
SAID DYESTUFF BEING SUITABLE FOR THE DYEING OF FIBROUS MATERIALS CONSISTING OF POLYESTERS, THE CLEAR, HEAVY AND REDDISH ORANGE DYEINGS OBTAINED ON SAID MATERIALS BEING DISTINGUISHED BY VERY GOOD FASTNESS PROPERTIES TO IRONING, TO WET PROCESSING, TO WASTE GAS AND TO LIGHT.
摘要:
A process for the preparation of fast dyeings or prints on synthetic fibrous materials which comprises treating the said fibrous materials in aqueous dispersion or in an organic solvent with dyestuffs of the formula IN WHICH R1 represents alkyl from one to four carbon atoms being unsubstituted or substituted by methoxy or ethoxy, and R2 represents phenyl being unsubstituted or substituted by fluorine, chlorine, bromine, alkyl or one to four carbon atoms, alkoxy of one to four carbon atoms, trifluoro-methyl, nitro, hydroxy, cyano, carbo(lower)alkoxy, acetyl, benzoyl, phenyl or phenoxy, the yellow dyeings or prints so obtained being distinguished by excellent fastness properties, particularly by a very good fastness to light and a high fastness to sublimation.
摘要:
IN WHICH A represents a linear branched alkylene group of 1 to 4 carbon atoms being unsubstituted or substituted by hydroxyl, methoxy, ethoxy, or phenoxy, B represents phenyl being unsubstituted or substituted by fluorine, chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, trifluoromethyl, cyano, carbo(lower)alkoxy, nitro, acetyl, benzoyl or phenyl or by combinations of two members thereof, or naphthyl, X represents -NH- or a direct linkage, and R represents hydrogen, acetyl, propionyl or benzoyl, the yellow dyeings or prints so obtained being distinguished by excellent fastness properties, particularly by a very good fastness to light, a high resistance to sublimation and furthermore, by very good colour yields.
A process for the preparation of fast dyeings or prints on synthetic fibrous materials, which comprises treating the said fibrous materials in an aqueous dispersion or in an organic solvent with a dyestuff of the formula (1)
摘要:
A PROCESS FOR THE PREPARATION OF FAST DYEINGS AND PRINTS ON FIBROUS MATERIALS CONTAINING HYDROXY GROUPS OR NITROGEN, WHICH PROCESS COMPRISES APPLYING WATER-SOLUBLE ORGANIC DYESTUFFS WHICH CONTAIN AT LEAST A GROUP OF THE FORMULA
-SO2-CH2-CH2-O-CO-NH-X
IN THE MOLECULE IN WHICH GROUP X IS A HYDROGEN ATOM OR AN -SO3H- GROUP ON THE SAID FIBROUS MATERIALS AND FIXING THEM AT NORMAL OR AT ELEVATED TEMPERATURE OR UNDER THE ACTION OF HEAT YIELDING VERY VALUABLE, INTENSE DYEINGS AND PRINTS WICH ARE VERY STABLE WHEN BEING SUBJECTED TO TREATMENTS OF WASHING AND TO THE ACTION OF LIGHT. THEY HAVE ALSO A REMARKABLE FASTNESS TO WATER, SEAWATER, RUBBING, IRONING, ACIDS, ALKALIS AND SOLVENTS. WHEN BEING FINISHED AFTERWARDS WITH SYNTHETIC RESINS IN AN ACID MEDIUM, DYEINGS AND PRINTS OF THE INVENTION SHOW ADVANTAGEOUS PROPERTIES.
