摘要： NEW METALLIZED POLYAZO DYES WHICH ARE NOTABLE FOR THEIR IMPROVED POWDER OF EXHAUSTION ON LEATHERS OF LOW AFFINITY AND ARE USED FOR DYEING AND PRINTING VARIOUS TYPES OF LEATHER. IT IS DESIRABLE FOR THESE DYES TO CONTAIN AS BASIC STRUCTRAL UNIT A GROUP OF THE FORMULA

1-((-)O-),3-(HO-),6-((2-((-)O-),3,5-DI(O2N-)PHENYL)-N=N-),

((PHENYL-NH-)PHENYL)-N=N-)BENZENE 1-((-)O-),3-

(HO-),6-((2-((-)O-),3,5-DI(O2N-)PHENYL)-N=N-)BENZENE

ME(+4)

IN WHICH THE AROMATIC RING B BEARS PREFERABLY AN

-SO3H-

AND AN -NO2- GROUP. THE MOLECULE MAY CONTAIN UP TO THREE ADDITIONAL ARYLAZO GROUPS BUT PREFERABLY NOT MORE THAN ONE.

摘要： AZO DYES AND THEIR METAL COMPLEX COMPOUNDS ARE FORMED BY COUPLING 1 OR 2 MOLES OF A DIAZO COMPONENT WITH A BIS-1-(2-HYDROXY-3-CARBOXYPHENYL METHANE. THEY ARE HIGHLY SUITABLE FOR DYEING LEATHER, FOR WHICH THEY HAVE VERY GOOD PENETRATIVE PROPERTIES AND YIELD LIGHT-FAST DYEINGS.

摘要： NEW POLYAZO DYES PRODUCED BY COUPLING A MONOAZO COMPOUND, WHICH IS PREPARED FROM A DIAZOTIZED 1-AMINO8 - HYDROXYNAPHTHALENE-MONOSULPHONIC OR -DISULPHONIC ACID OR ONE OF ITS 3''- OR 4''-AMINOBENZOYLAMINO DERIVATIVES AND A 1,3-DIHYDROXYHYDROXYMETHYLBENZENE, WITH 1 TO 2 MOLES OF ANY DESIRED DIAZO COMPONENT, FOR THE DYEING OF LEATHER. THE DYES HAVE THE FORMULA

1-((8-HO,(R-N=N)P,(HO3S)Q,(HO3S-)NAPHTH-1-YL)-(NH-CO-

((R1)R-PHENYLENE))M-N=N-),2,4-DI(HO-),(HO-CH2-),(R-N=N-)-

BENZENE

WHEREIN R IS THE RADICAL OF A DIAZO COMPONENT, R1 IS HALO, ALKYL, SUBSTITUTED ALKYL OR ALKOXY, M IS 0 OR 1, P IS 0 OR 1, Q IS 0 OR 1, R IS 0 OR 1.
