Abstract
An improved photoelectrophoretic imaging method is disclosed wherein a blocking layer is provided with a coating which interacts, in the dark, with the pigment particles of the imaging suspension so as to provide a uniformly charged imaging suspension upon exposure of the suspension to an electric field. The coating comprises a compound selected from the group consisting of inorganic salts of lithium, iodine, tin and iron.
