    摘要： An electrophotographic photoreceptor including at least an electroconductive substrate, a photosensitive layer formed on the substrate and a protective layer formed on the photosensitive layer and including a binder resin, wherein when a solution in which the binder resin is dissolved in an organic solvent incompatible with water is mixed with deionized water having an electroconductivity not greater than 1 nullS/cm and substantially the same weight as that of the solvent while agitating, the water has an electroconductivity not greater than 2 nullS/cm.

    摘要： Polymer films are formed by electrocodeposition of solutions containing a dispersion of charged particles of a first polymer and charged particles of a second polymer. Microheterogeneous films are obtained having micro-domains of a minor component polymer dispersed in the major component polymer. Processes for preparing dispersions for electrocodeposition are also provided In a first process, two polymers are dissolved in a common solvent and then dispersed as small charged particles in another solvent which is a precipitant for both polymers. In another process, a dispersion of a first polymer is prepared by adding a solution of the first polymer to a dispersant solvent, and then a solution of a second polymer is dispersed in the dispersion of the first polymer. In another process, a solution of the second polymer is added to a dispersion of the first polymer which contains only a single non-solvent for the second polymer. In yet another process, a dispersion of the first polymer in a first solvent system is mixed directly with a dispersion of a second polymer in a second solvent system, resulting in a dispersion of the first and second polymers in a resulting solvent system of the first and second solvent systems. In yet another process, a block copolymer composed of two blocks is dissolved in a solvent, and then dispersed in a non-solvent to form the dispersion.

    摘要： 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.
