Abstract: WATER-SOLUBLE POLYAZO-DYESTUFFS OF THE FORMULA

1-((3,6-DI(HO3S-),7-(Y-N=N-),8-(HO-)NAPHTHYL)-N=N-),

2-(HO-),4,6-DI(X-),5-(((3-R1,4-(R-N=N-),5-(HO-)

PYRAZOL-1-YL),R2-PHENYL)-N=N-)BENZENE

SAID DYESTUFFS BEING EASILY SOLUBLE IN WATER AND BEING SUITABLE FOR THE DYEING OF LEATHER AND FUR SUEDES, THE DYEINGS OBTAINED ON SIAD MATERIALS MOSTLY SHOWING A YELLOWISHBROWN SHADE AND HAVING A GOOD RESISTANCE TO ACIDS, A GOOD LEVELLING AND PENETRATING POWER, AND POSSESSING GOOD PROPERTIES OF FASTNESS TO WATER, WASHING, PERSPIRATION, SOLVENTS AND TO LIGHT.
