发明名称	Process for dyeing leather with mixtures of dyes.
摘要	Zum Färben von Leder verwendet man Farbstoffmischungen, enthaltend mindestens zwei metallfreie Farbstoffe mit jeweils zwei Sulfo- oder Carboxygruppen und einem Molekulargewicht zwischen 790 und 1100. Vorzugsweise verwendet man eine Farbstofftrichromie-Mischung, enthaltend mindestens einen gelben Farbstoff der Formel (1), mindestens einen roten Farbstoff der Formel (2) und mindestens einen blauen Farbstoff der Formel (3) gemäss Anspruch 2. Mit diesen Farbstoffmischungen lässt sich Leder in brillanten Tönen färben.
