<p>The present invention relates to a sheet material for forming a dielectric for a plasma display panel capable of forming a dielectric layer having a high withstand voltage, a smooth surface, and excellent transparency, and a process for producing same. Furthermore, the present invention also relates to a process for producing a dielectric layer constituting a plasma display panel. The sheet material for forming a dielectric for a plasma display panel of the present invention is a freestanding porous sheet material formed from an inorganic dielectric powder and a thermoplastic resin and having a thickness of 350 mu m or less, and contains, as percentages by weight based on the total amount of the dielectric powder and the thermoplastic resin, the dielectric powder at 40% to 98% and the thermoplastic resin at 2% to 60%. Moreover, the process for producing a dielectric layer of the present invention employs thermocompression-bonding a sheet material for forming a dielectric for a plasma display panel at 80 DEG C to 180 DEG C to one surface of a glass substrate having electrodes fixed thereto, debindering at high temperature, and then sintering or fusing to form the dielectric layer. <IMAGE></p> |
