摘要： Methods of preparing a liquid electrographic toner composition are provided, wherein a polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions is first prepared in a hydrocarbon reaction solvent, wherein the hydrocarbon reaction solvent comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL. Toner particles are then formulated in the hydrocarbon reaction solvent and dried. The dried toner particles are then redispersed in a carrier liquid that is different from the reaction solvent, wherein the carrier liquid comprises less than about 10% aromatic components by weight and has a Kauri-Butanol number less than about 30 mL, to form a redispersed liquid electrographic toner composition. Preferred carrier liquids are silicone oils. Products and kits are also provided.

摘要： A testing procedure and method is provided for assessing the quality or acceptability of performance of individual liquid ink electrostatic toners on individual receptor surfaces. An approximately standard drop of the individual liquid toner is placed on the receptor to be tested. The drop is pressed onto the receptor and spread on the surface of the receptor (preferably before the drop has had time to partially evaporate or to have the liquid in the drop absorb or naturally spread on the receptor surface) under controlled conditions. The characteristics of the spread drop on the receptor surface are measured, and the characteristics are compared to parameters defining the characteristics expected from a liquid toner that define acceptable performance between toner and receptor. In this manner the relative performance of individual toners on individual receptor surfaces can be evaluated independent of electrostatic effects. This can be important, as the electrostatic effects bring another parameter of performance into evaluation of the compatibility of the toner and receptor and can misdirect research for adjusting their compatibility.
摘要翻译：提供了一种测试程序和方法，用于评估单个液体静电调色剂在各个接收器表面上的性能的质量或可接受性。将单个液体调色剂的大致标准滴放置在待测试的受体上。在受控条件下，将滴落在受体上并扩散在受体的表面上（优选在滴下已经有时间部分蒸发或使液滴中的液体吸收或自然扩散在受体表面上之前）。测量受体表面上扩散滴的特征，并且将特性与限定从调色剂和受体之间确定可接受性能的液体调色剂预期的特征的参数进行比较。以这种方式，可以独立于静电效应来评估各个调色剂在各个受体表面上的相对性能。这可能是重要的，因为静电效应将性能的另一参数带入评估调色剂和受体的相容性，并且可以误导调查其相容性的研究。

摘要： A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method includes the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit including a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further includes contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.

摘要： The present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing with a relatively narrow particle size distribution. The present invention uses extrusion techniques to coat wet toner particles onto a substrate surface. Because the resultant coating has a relatively large drying surface area per gram of particle incorporated into the coating, drying may occur relatively quickly under moderate temperature and pressure conditions. After drying, the dried toner particles are readily recovered and may then be used in dry or even wet toners for electrophotographic applications.
