Abstract: Provided is a process for producing a glass plate with a conductive printed wire, which does not require a screen plate for each model, facilitates adjustments for desired heat generation performance or antenna performance, has an excellent adhesion to a glass plate surface, and minimizes surface roughness. The process for producing a glass plate with a conductive printed wire is characterized in that a laminate comprising a layer obtained by electro printing a first conductive toner having a number standard average particle size (D50) of 10 ?m<D50?50 ?m and a layer obtained by electro printing a second conductive toner having a particle size (D50) of 5 ?m?D50?10 ?m is formed on a surface of a glass plate and the glass plate is heated to fire the toners to thereby form a conductive printed wire having a predetermined pattern on the surface of the glass plate.

A toner for electronic printing, which comprises toner matrix particles comprising conductive fine particles, a heat decomposable binder resin and glass frit, and heat decomposable organic resin fine particles attached on the surface of the toner matrix particles, wherein the heat decomposition temperature of the organic resin in the heat decomposable organic resin fine particles is lower than the heat decomposition temperature of the heat decomposable binder resin.

Abstract: A process for producing a glass plate with conductive printed wiring which does not require a new screen for each model and which can easily be adjusted for desired electric heating performance or antenna performance, and a conductive toner for such a process. A conductive toner comprising at least one member selected from the group consisting of a thermoplastic resin (A) having carboxyl groups introduced and having T100 of from 300 to 450° C., a polypropylene (B) having carboxyl groups introduced, and a thermoplastic resin (C) having T100 of from 300 to 450° C., conductive fine particles, and glass frit-containing particles. T100 is a temperature at the time when a weight change of the resin has become no longer observed during a temperature rise from room temperature at a rate of 10° C./min by means of a thermogravimetric analyzer (TG).
