The invention provides heteroanellated aminophenols of the general formula (I) wherein ring A has the meaning given in claim 1, as well as a process for the preparation of such aminophenols. Furthermore, the invention provides azo compounds of the general formula (II) wherein ring A, n and the substituents have the meaning given in claim 3, as well as a process for the preparation of those compounds from aminophenols. In addition, the invention provides azomethine compounds of the general formula (III) wherein ring A and the substituents have the meaning given in claim 6, as well as a process for the preparation of those compounds from aminophenols. The invention describes the use of compounds (II) and compounds (III) for the mass coloration of substrates, as colorants in electrophotographic toners and developers, in powders and powder coating materials, in ink-jet inks and in cosmetic compositions.
