Abstract
The electrostatic information recording medium of the invention has on at least an electrode an information recording layer comprising a product obtained by contact of a polymer having a fluorine-containing aliphatic ring structure with fluorine gas, on which layer a latent image charge trap is retained. This electrostatic information recording medium enables electrostatic information such as an electrostatic latent image to be recorded in the form of a charge trap rather than an electrostatic charge, and so may be used as an electrostatic printing master by way of example.
