Abstract

Hydrazone dyes of the formula <IMAGE> where R is alkyl, cycloalkyl, aralkyl or aryl, and R1 and R2 are each alkyl or aralkyl, or R1 and R2 together are a ring, X is oxygen or sulphur, and An<(-)> is an anion, and where the rings a and b and the cyclic and acyclic substituents can carry nonionic radicals and/or a carboxyl group, are used for dyeing and printing synthetic and natural materials, in particular polyacrylonitrile fibres and acid-modified polyester and polyamide fibres.
