Title: CERAMIC TONER FOR ELECTRO-PHOTOGRAPHIC PRINTING
Abstract:
The invention relates to a ceramic toner which is transferable to a high-temperature resistant glass, glass ceramic or ceramic substrate by means of electrophotographic printing and which can be fired in a subsequent temperature process, containing colour pigment particles in addition to special glass flow particles. According to the invention, said ceramic toner is provided with 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, vaporises 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.
