Electrostatic information recording medium

摘要

PCT No. PCT/JP92/01336 Sec. 371 Date Oct. 25, 1993 Sec. 102(e) Date Oct. 25, 1993 PCT Filed Oct. 15, 1992.The electrostatic information recording medium of the present invention has an electric charge retaining layer 11 stacked on at least an electrode layer 13, as shown in FIG. 1 . The electric charge retaining layer is formed from either +E,crc/1/ resin selected from among fluorocarbon resins and polystyrene resins, and an insulating organic substance having no photoconductivity. The electrostatic information recording medium may be produced, as shown in FIG. 5 , by stacking an insulating resin layer 10 on an electrode layer 13, stacking a photoconductive or electrically conductive fine particle layer 11 on the insulating resin layer 10, and further stacking an insulating resin layer 12 on the fine particle layer 11 to a thickness of 0.1 mu m to 1 mu m. The electrostatic information recording medium is superior in electric charge retaining characteristics, particularly in the performance of retaining positive information electric charge, and also excellent in heat resistance and moisture resistance. If the insulating resin layers 10 and 12 are formed by coating using a fluorocarbon resin solution, the electrostatic information recording medium can be produced with excellent processability.
