Abstract:

THIS REPORT INVOLVES A PROJECT DIRECTED TOWARD IMPROVING ELECTROSTATIC THERMOPLASTIC PHOTOGRAPHY. THE PREFERRED APPROACH HAS BEEN TO COMBINE CHARGE TRANSFER THROUGH A THIN FILM OF INSULATING LIQUID WITH DEVELOPMENT OF THE ELECTROSTATIC IMAGE BY FROST-TYPE DEFORMATION. EFFORT HAS ALSO BEEN EXPENDED ON FORMULATION AND EVALUATION OF PANCHROMATIC PHOTORECEPTORS BASED ON MULTILAYER STRUCTURES. CHARGE TRANSFER THROUGH A THIN LAYER OF LIQUID WAS SELECTED FOR THIS STUDY RATHER THAN TRANSFER OF THE ELECTROSTATIC IMAGE BY AIR BREAKDOWN BECAUSE EXPERIENCE INDICATED IT WOULD OVERCOME PROBLEMS OF HIGH VOLTAGE THRESHOLD, CRITICAL GAP SPACING AND NON UNIFORMITY OF TRANSFER ASSOCIATED WITH AIR BREAKDOWN. FROST DEVELOPMENT OF THE TRANSFERRED ELECTROSTATIC IMAGE WAS PREFERRED BECAUSE IT PROVIDES A THERMOPLASTIC IMAGING METHOD CAPABLE OF CONTINUOUS TONE RESPONSE IN THE ABSENCE OF ANY OPTICAL OR PHYSICAL SCREENING OF THE IMAGE. HEAT-SOFTENING A THIN THERMOPLASTIC FILM BEARING THE ELECTROSTATIC PATTERN GIVES A LIGHT-SCATTERING DEFORMATION IMAGE OF HIGH RESOLUTION CONTINUOUS-TONE QUALITY
