    摘要： DYESTUFFS WHICH ARE FREE FROM WATER-SOLUBLIZNG GROUPS DISSOCIATING ACID IN WATER AND CORRESPONDING TO THE FORMULA 1-(A-N=N-),2-X,4-(R-O-CH2-CH(-O-Z)-CH2-N(-CH2-CH2-CN)-), 5-Y-BENZENE WHEREIN A REPRESENTS THE RESIDUE OF A DIAZO COMPONENT OF THE BENZENE SERIES HAVING AT LEAST ONE NON-IONOGENIC, ELECTRON-ATTRACTING SUBSTITUENT OR THE RADICAL OF A DIAZO COMPONENT OF THE HETEROCYCLIC SERIES, X AND Y REPRESENT INDEPENDENTLY OF EACH OTHER, HYDROGEN, A LOWER ALKYL GROUP, LOWER ALKANOYLAMINO OR HALOGEN, Z REPRESENTS AN ACYL RADICAL AND R REPRESENTS AN OPTIONALLY SUBSTITUTED LOWER ALKYL, CYCLOALKYL, ARALKYL OR ARYL RADICAL. THESE DYESTUFFS ARE DISTINGUISHED BY GOOD AFFINITY ESPECIALLY FOR POLYESTER FIBERS, AFFORDING DYEINGS ON THESE FIBERS WHICH HAVE GOOD FASTNESS PROPERTIES AND ESPECIALLY GOOD FASTNESS TO LIGHT AND SUBLIMATION.

    摘要： WATER-INSOLUBLE DYESTUFFS ARE PROVIDED HAVING THE FORMULA:

    A,(D1-(N=N-B(-Z)(-Z''))M-N=N-),(Y-CO-X-OOC-)-BENZENE

    OR THE FORMULA

    A,(D2-(N=N-B(-Z)(-Z''))M-N=N-),(Y-COO-X-OOC-)-BENZENE

    IN WHICH B REPRESENTS A P-PHENYLENE OR P-NAPHTHYLENE RADICAL LINKED TO THE NITROGEN ATOMS, M REPRESENTS THE NUMBERS 0 OR 1, X REPRESENTS AN ALKYLENE RADICAL HAVING UP TO 4 CARBON ATOMS, Z AND Z'' EACH REPRESENT A HYDROGEN OR HALOGEN ATOM OR AN ALKYL, ALKOXY, OR ACYLAMINO GROUP HAVING UP TO 4 CARBON ATOMS, Y REPRESENTS AN ALIPHATIC, ARYLALIPHATIC, AROMATIC OR HETEROCYCLIC RADICAL, D1 REPRESENTS THE RESIDUE OF A COUPLING COMPOUND OF THE BENZENE, DIPHENYLENEOXIDE, INDAZOLE, COUMARIN, ACETYLACETARYLIDE, PYRAZOLONE OR HYDROXY-QUINOLINE SERIES, D2 REPRESENTS THE RESIDUE OF A COUPLING COMPOUND OF THE BENZENE, DIPHENYLENE-OXIDE, INDAZOLE, COUMARIN, ACETYLACETARYLIDE, HYDROXYQUINOLINE, 1 - PHENYL-3-METHYL-PYRAZOLONE OF 1-PHENYL-3CARBONAMIDOPYRAZOLONE SERIES, THE NUCLEI A, B, D1, D2 AND Y CONTAINING NO SOLUBILISING ACID GROUPS. THESE DYESTUFFS ARE USEFUL FOR THE COLOURATION OF HYDROPHOBIC TEXTILE MATERIALS AND MAY BE PREPARED FROM NOVEL DIAZOTISABLE BASES OF THE GENERAL FORMULA:

    Y-COO-X-OOC-ANILINE

    IN WHICH X, Y, Z AND Z'' ARE AS DEFINED ABOVE. THE SHADES OBTAINED ARE REMARKABLY FAST TO THERMAL FIXATION, SUBLIMATION, CREASING, COMBUSTION GASES, OVERDYEING, DRY CLEANING, CHLORINE AND WET TESTS. THE RESERVE OF NATURAL FIBRES AND THE DISCHARGEABILITY ARE GOOD. THE FASTNESS TO LIGHT IS REMARKABLE EVEN WITH LIGHT SHADES AND THE DYESTUFFS RESIST BOILING AND REDUCTION AT TEMPERATURES BETWEEN 80* C. AND 220* C.
