Abstract
Abstract Process for the bulk dyeing of polyesters, characterised in that the dyestuffs used are anthraquinone derivatives of the formula ##SPC1## Wherein Q denotes one of the bridge members --O-- or --CO--, R denotes hydrogen or an alkyl group containing 1-4 carbon atoms, Ar denotes an aryl group, n denotes a number from 1 to 4, X, Y and Z denote an amino, hydroxyl, alkoxy, aryloxy, alkylmercapto, arylmercapto, arylamino or aroylamino group or halogen and a, b and c each denote zero or a number from 1 to 4, with the sum of n+a+b+c being a number from 1 to 6.
