Abstract

The dyes are of formula: (in which R1 is a cycloalkyl, aryl, aralkyl or alkyl gp., and R2 is H or is selected as R1, or R1 and R2 form a 5-or 6-membered ring; Z is H or nitro and one Y is SO3H, while the other is H), and they are suitable for dyeing and printing org. materials, esp. synthetic or natural polyamides or fibre mixts. contg. these, giving yellow-brown shades of good levelness and general fastness, esp. to light. Esp. suitable for carpets and dyeing or printing from concd. aq. solns.
