Abstract
Abstract The invention relates to water-insoluble quinophthalone dyestuffs of the formula ##STR1## in which T represents W--Ar or ##STR2## and Ar denotes aryl, W denotes oxygen, sulphur or N--R, R denotes hydrogen or alkyl, A denotes alkylene, O R 1 denotes alkyl or aryl, R 2 denotes hydrogen or alkyl, X denotes halogen, alkyl, alkoxy, nitro or acylamino, Y denotes hydrogen or halogen, Z denotes hydrogen, alkyl or halogen and n denotes a number from 0 to 3 The new dyestuffs and their mixtures are distinguished by good affinity to polyester fibres and good general fastness properties.
