摘要： The electrostatic information recording medium according to the present invention comprises an electrode layer and an electric charge retaining layer. By improving the laminating method of electric charge retaining layer or by improving the layer arrangement or by converting electrostatic information to the visible information or position information, high information retaining property can be obtained and the accumulated electrostatic information can be maintained for long period. In the electrostatic information recording method according to the present invention, an electrostatic information recording medium is placed face-to-face to a photosensitive member having photoconductive layer on an electrode. The image exposure is performed by applying voltage between two electrodes, and the electrostatic information corresponding to the image exposure is recorded on the electrostatic information recording medium. The electrostatic information recorded in the electric charge retaining layer is easily reproduced by reading surface potential and by amplifying and outputting, or by electro-optical reading method, and further, by toner development. The electrostatic information recording medium according to the present invention has excellent memory capacity with information density of 8.times.10.sup.8 bits/cm.sup.2. For example, it is possible to record the information by electrostatic information recording method using a photosensitive member, to record analog, digital, image, sound and (0.1) information, and to apply for electrostatic recording card and the like.

摘要： 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.

摘要： A liquid toner and an ink composition, which comprise a dispersion of copolymer resin particles composed of at least two different monomer components in a dispersion medium. The copolymer resin particles and the dispersion medium are related to each other such that the difference .DELTA..delta..sup.1 between the solubility parameter value .delta.p.sup.1 of a homopolymer composed only of at least one monomer component in the copolymer resin and the solubility parameter value .delta.s.sup.1 of the dispersion medium is not smaller than 1.0, and that the difference .DELTA..delta..sup.2 between the solubility parameter value .delta.p.sup.2 of a homopolymer composed only of at least one other monomer component and the solubility parameter value .delta.s.sup.1 of the dispersion medium is not larger than 1.0, and further that the difference .DELTA. between .DELTA..delta..sup.1 and .DELTA..delta..sup.2 (.DELTA..delta..sup.1 -.DELTA..delta..sup.2) is at least 0.5. Moreover, each copolymer resin particle comprises a nuclear portion which is insoluble in the dispersion medium, and an outer skin portion which wraps the nuclear portion, and which is soluble or swellable in the dispersion medium. The liquid toner is a dispersion of the copolymer resin particles in an electrically insulating dispersion medium. The liquid toner is free from sedimentation, aggregation or other problem even if the pigment content is increased, and hence excellent in dispersibility and free from gelation. The ink composition is a dispersion of the copolymer resin particles in a dispersion medium. Even if the pigment or other particle content is increased, sedimentation, aggregation or other problem will not occur. Thus, the ink composition exhibits excellent dispersibility and is free from gelation and superior in coatability.

摘要： Information recording media enable images to be recorded and reproduced with high resolution, wherein oozing of liquid crystal material thereof is prevented and the information recorded without unevenness. A first recording medium has an information recording layer comprising a liquid crystal phase and an ultraviolet curing resin phase. The information recording layer is stacked on an electrode layer provided on a substrate by coating a mixed solution of liquid crystal and ultraviolet curing resin material on the surface of the electrode layer and then irradiating the coating by irradiation with ultraviolet rays, thereby forming a cured skin layer of the resin material on the outer surface of the information recording layer. A second recording medium has a transparent electrode layer additionally provided on the information recording layer of the first recording medium. A third recording medium has an electrode layer, a photoconductive layer, an information recording layer, and an electrode layer, in successive order. A fourth recording medium has a transparent insulating layer or semiconductor layer interposed between the photoconductive layer and the information recording layer of the third recording medium. According to an information recording and reproducing method employing the first recording medium, a gradually increasing voltage is applied between a photosensitive member and the recording medium. As a result, the effective voltage applied to the liquid crystal layer can be raised, enabling increased modulation, improved contrast and responsiveness.
