Zusammenfassung:Coloured magnetically attractable toner powder containing magnetically attractable material and a colouring substance containing thermoplastic resin and, as colouring constituent, a mixture of fluorescent dyes at least one dye according to the formula of the formula sheet, wherein X is an anion, such as, for example, tetrafluoroborate, boron fluoride, perchlorate, hexafluorozirconate or ethyl sulphate. The dye is preferably used in combination with a fluorescent dye of the type C.I. Basic Violet 11:1 (C.I. 45174) and possibly yellow-fluorescent dye. Improved magenta and red toner powders are obtained in this way.
