摘要： An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.
摘要翻译：用于液体接触静电印刷（CEP）的图像承载制品由满足CEP工艺所需的一致性和热稳定性的聚合物形成。通过液体CEP中的图像承载制品对调色剂载体液体的过度吸收导致图像承载制品的劣化，并降低图像承载制品的使用寿命。调色剂载体流体的吸收可以通过添加氧化物，含有苯基端基的硅氧烷弹性体，氟硅氧烷或增加甲基硅氧烷的交联密度来控制。

摘要： An electrostatographic printing machine and apparatus that utilizes a two layer roll charger for contact charging of photoreceptors. The charger includes a liquid retentive foam layer fitted over an electrically conductive shaft. The shaft can be solid or porous, the later requiring a separate liquid reservoir. The second layer is a thin liquid permeable member, over the foam layer, which transmits water at a slow, but controlled rate during the rotation of the roller. The roller may rotate synchronously with the photoreceptor or be allowed to slip on the photoreceptor surface to improve uniformity and contact. The membrane increases life by controlling the runout of liquid from the repository. Also, the present invention permits charging over photoreceptor pinholes.

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.
