Abstract: An electrode 2c and a pinene polymer recording layer 2a with a molecular weight of 500 to 10000 are successively stacked on a substrate 2c, as shown in FIG. 3. By carrying out thermal development, information electric charge that is formed on the resin surface is formed into a thermally stable frost image without decay of the information electric charge. Since no photoconductive layer is needed, when transmitted or reflected light is used to reproduce the frost image, there is no effect of the coloring of a photoconductive layer. If exposure is effected under the application of a voltage, since the depth of dimple patterns of a frost image varies in accordance with the quantity of exposure energy, tonal reproducibility is obtained. In addition, it is possible to obtain high resolution and make an original for OHP, a microfilm, a slidefilm, etc. which is of good quality and has high fidelty to the original document.

Abstract: To form an optical image, an imagewise pattern of conductivity is formed in a semiconductor material. Exposing the material to an intense radio-frequency field causes generation of heat in the conductive areas. The semiconductor is made of a heat-sensitive material or includes a heat-sensitive material. The heat-sensitive material responds to heat by physical changes which can be optically detected. Preferably the semiconductor is a photoconductor with surface charge capability retention which allows formation of a conductivity pattern by normal xerographic processes.

Abstract: The record carrier according to the invention comprises a substrate on which an electrode is provided which, on the side remote from the substrate, has a low-ohmic photoconductive layer which is covered with a second transparent electrode which is provided wihh a thermoplastic layer. For storing information the electrodes are connected to a voltage source and the thermoplastic layer is charged electrostatically and exposed in known manner. Upon exposure of an area of the thermoplastic layer, the light will fall through the transparent electrode on the low-ohmic photoconductive layer. As a result of the current passage, Joulean heat is produced which heats the thermoplastic layer in the place of the exposed area and softens it thereby deforming the layer by electrostatic forces in accordance with the charge.The thermoplastic layer may, in known manner, also have photoconductive properties or be provided with a further photoconductive layer.

Abstract: In a thermoplastic-photoconductor holographic recording medium in the form of several transparent layers over a transparent substrate, such as an optically transparent electrically conductive layer, then a photoconductor layer and a thermoplastic layer over such as glass or Mylar, a conventional material such as gold or platinum has been used as a transparent conductive layer. It is desired to use a less precious metal such as nickel-chromium (NiCr) as the conductive layer, however a limitation has been found in that an unwanted dark charge injection occurs from the NiCr to the photoconductive layer. This causes poor charge acceptance and therefore results in poor halogram formation. Herein a mono atom thick layer of the NiCr is treated and becomes on oxide layer which forms an effective charge blocking layer to dark charge injection.

This reduces the charge contrast and causes poor performance of the thermoplastic-photoconductive device.
