    摘要： Dyes of the formula ##SPC1##WhereinEach of R, R.sub.1, R.sub.2 and R.sub.3 is independently hydrogen, halo, nitro, unsubstituted or substituted alkyl or alkoxy, carboxy or sulfo,R.sub.4 is a diazo component radical, and Me is a metal atom,Are useful for dyeing and printing of leather. They exhaust well on leathers of low affinity and give level dyeings. The dyeings exhibit good fastness to light, water, washing, perspiration, ironing and formaldehyde.
