CERAMIC TONER FOR ELECTRO-PHOTOGRAPHIC PRINTING

摘要

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.
