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 dark charge injecting agent dispersed in an electrically insulating, alkyd resins derived from dibasic acids and polyhydric alcohols. Subsequent exposure to electromagnetic radiation to which at least some of the particles are sensitive then results in the formation of optically positive and negative images.
