Ceramic toner for electro-photographic printing

摘要

A ceramic toner which is transferable to a high-temperature resistant glass, glass ceramic or ceramic substrate by electrophotographic printing and which can be fired in a subsequent temperature process, containing color pigment particles in addition to special glass flow particles. According to this invention, the ceramic toner has a thermoplastic synthetic matrix which melts in a homogeneous manner on the substrate within a temperature range of 100° C.-400° C. and which, within the temperature range of 300° C.-500° C., vaporizes in an almost residue-free manner and/or decomposes in order to obtain a toner which can be transferred especially in a direct printing mode and which has almost no synthetic matrix residue after firing.
