摘要： A photosensitive member having an electrode on the front surface thereof and a photoconductive layer stacked on the electrode. The member faces an electrostatic data recording medium which comprises a charge-holding layer having an electrode on the back surface. The photosensitive member may be in contact with the recording medium. When a voltage is applied across the electrodes, an exposure is carried out to form an electrostatic charge pattern in the electrostatic data recording medium, the electrostatic charge pattern being in correspondence with the exposure pattern. The layer structure of the photosensitive member and the photoconductive layer and the method of forming the photoconductive layer are improved, enabling the recording of electrostatic data on the electrostatic data recording medium with high sensitivity. Further, the contrast in charges of data between the exposed portion and the unexposed portion can be improved.

摘要： An electrostatic information recording medium (3) composed of an electrostatic information recording medium electrode (13) and a charge holding layer (11) put thereon, wherein the layer (11) is formed from a fluororesin composed of repeating ring structure units of general formulae (1) and/or (2) and having such a molecular weight as to give an intrinsic viscosity of at least 0.1 at 50 °C, wherein n is 1 or 2. The above constitution serves to hold persistently the information charges stored in the charge holding layer. Because the information storage means is an electrostatic charge unit, the information stored in this recording medium has a high quality and a high resolution, the information processing is simple, a long-term storage is possible, and the stored information can be reproduced arbitrarily and repeatedly with an image quality meeting the purpose of use.

摘要： An electrostatic information recording medium of the invention comprises: an electrode layer (13) and a charge-holding layer, wherein the charge-holding layer is made up of a laminate of a resin layer (11a) having a low glass transition temperature and a heat-resistant insulating layer (11b); at least an electrode layer (13) and a charge-holding layer, as well as a polymer layer provided on the charge-holding layer, the polymer layer containing a pentaflurostyrene as a monomer component and having a weight average molecular weight of 10,000 to 2,000,000; a photoconductive layer and a charge-holding layer arranged between a pair of electrodes, wherein an electrostatic latent image formed by the exposure while applying a voltage across the two electrodes or formed by the application of a voltage while effecting the exposure, is held on the surface of the charge-holding layer by peeling the charge-holding layer from the electrode; or a charge transit layer formed on the electrode, wherein information by toner is recorded on the surface of the charge transit layer and when an electrostatic charge is given to the surface, the charge given onto the toner is poured into the charge transit layer through electrically conductive material of toner to form electrostatic information corresponding to toner information on the charge transit layer maintaining excellent electrostatic information-holding characteristics, and wherein the electrostatic information stored in the electrostatic information recording medium remains very stable since it is stored in the charge-holding layer and, at the time of reproducing information, the potential difference between the electrode and the surface potential is measured to easily detect the potential difference, enabling the information to be easily reproduced maintaining high quality and high resolution.

摘要： This invention involves the production of sound tracks for motion picture film. Prior motion picture film sound tracks could not overlap the photographic image and were placed on the edge of the film, nor were they digitally coded to produce high fidelity. The motion picture film of the invention has a plurality of digitally coded sound track images which overlay at least a portion of the visible image (13, 14) area of the film and are colorless and transparent to visible light, but fluoresce when exposed to ultraviolet light. An electrostatic imaging process using a fluorescent toner which may be a polymer having covalently bonded 3-phenyl-7[amido or imido]-coumarin, certain substituted stilbenes or N-alkyl-4-aminophthalimides is used to form the sound track image.

摘要： Copolymer comprising a major amount of hydrophobic monomer such as acrylic ester, methacrylic acid ester, aromatic vinyl and vinyl cyanide, and a minor amount of hydrophilic monomer such as acrylic acid and methacrylic acid is stably dispersed in water without the aid of emulsifier. An electrostatically-recording medium is produced by the application of the aqueous dispersion of said copolymer on a supporting member having a low-resistance back surface to form an image-holding layer. This electrostatically-recording medium has advantages in which, upon its production, there is no need of using inflammable solvent and emulsifier and also, upon high-speed imaging process, high-quality images are provided even under high-humidity condition. Polyethyleneimine and polyepoxy compounds may be added to the aqueous dispersion to crosslink the copolymer, thus resulting in the improvement of recording characteristics. To be further effective in writing quality, polyacrylamide may be added.
