Abstract
Abstract Anthraquinone derivatives which, in one of their tautomeric structures, correspond to the formula ##STR1## in which A denotes an anthraquinone radical which is free from sulphonic acid groups, is optionally further substituted and preferably consists of at most 5 fused rings, m denotes a number from 1 to 4, preferably 1 or 2, R denotes a substituent and n denotes 0, 1, 2, 3 or 4, processes for their preparation, their use for pigmenting organic macromolecular substances, and the material pigmented in this manner.
