Title:
ELECTROSTATIC INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/1991/014206
Kind Code:
A1
Abstract:
An electrostatic information recording medium (3) composed of an electrostatic information recording medium electrode (13) and a charge holding layer (11) put thereon, wherein the layer (11) is formed from a fluororesin composed of repeating ring structure units of general formulae (1) and/or (2) and having such a molecular weight as to give an intrinsic viscosity of at least 0.1 at 50 �C, wherein n is 1 or 2. The above constitution serves to hold persistently the information charges stored in the charge holding layer. Because the information storage means is an electrostatic charge unit, the information stored in this recording medium has a high quality and a high resolution, the information processing is simple, a long-term storage is possible, and the stored information can be reproduced arbitrarily and repeatedly with an image quality meeting the purpose of use.
