Abstract

Dye formulations for transfer printing which in addition to conventional ingredients contain dyes of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 are hydrogen, hydroxy, chloro, bromo or alkylamino substituents, one of R.sup.1 to R.sup.3 being different from hydrogen. The dyes are distinguished by a comparatively very low transfer temperature.
