摘要：
Compounds of the formula ##STR1## in which R.sub.1 is hydrogen or nitro,Each of R.sub.2 and R.sub.3, independently, is --OH or --NH.sub.2,R.sub.4 is hydrogen, nitro or (C.sub.1-4) alkyl,R.sub.5 is hydrogen, nitro or (C.sub.1-4) alkoxy,R.sub.6 is hydrogen, (C.sub.1-4) alkyl, (C.sub.1-4) alkoxy, --COOM or --SO.sub.3 M,R.sub.7 is hydrogen or --SO.sub.3 M,R.sub.8 is hydrogen or the radical of a diazo component, andM is a hydrogen ion or a non-chromophoric cation,And mixtures thereof, in metallized form or unmetallized form, which compounds in metallized form are useful as dyes for paper and leather. The dyeings exhibit notable fastness to light, hard water, washing, perspiration, alkali, acid and buffing.
