摘要： A non-volatile, fast-set, heat-dry plastisol vehicle for printing inks is provided comprising a finely divided, substantially water-insoluble, thermoplastic, film-forming polyvinyl resin that is solid at room temperatures dispersed in a sufficient amount of a single compatible liquid plasticizer to form a plastisol, and an effective amount of a tackifying agent consisting essentially of liquid polystyrene to inhibit ''''flying'''' of the plastisol from a printing press and the like. After application to a backing member, usually paper stock, in a printing operation, the plastisol is heated above the softening temperature of the polyvinyl resin which then swells and effectively absorbs the liquid plasticizer and liquid polystyrene. Preferably, the polyvinyl resin is pigmented to provide a contrasting color with respect to the backing member on which it is printed. The use of liquid polystyrene as a tackifying agent reduces not only the number of different plasticizers needed but also the total amount of plasticization as compared to prior practice.
摘要翻译：提供了用于印刷油墨的非挥发性，快速固化的热干性增塑溶胶载体，其包含细分的基本上不溶于水的热塑性成膜聚乙烯基树脂，其在室温下为固体，其分散在足量的单一相容的液体增塑剂以形成增塑溶胶，以及有效量的基本上由液体聚苯乙烯组成的增粘剂，以抑制增塑溶胶从印刷机“飞”等。在印刷操作中涂布到背衬构件（通常为纸料）之后，将增塑溶胶加热到高于聚乙烯基树脂的软化温度，然后膨胀并有效地吸收液体增塑剂和液体聚苯乙烯。优选地，聚乙烯基树脂被着色以提供与其印刷的背衬构件对比的颜色。使用液体聚苯乙烯作为增粘剂，与现有技术相比，不仅减少了不同的增塑剂的数量，而且减少了增塑剂的总量。

摘要： The printing plate and process for preparing the same described herein comprises a printing plate suitable for dry lithography having in the non-image producing areas an ink repellent coating such as a cured elastomeric organopolysiloxane and in the ink receptive image producing areas the same cured elastomeric organopolysiloxane coated with a fused toner, and having under said organopolysiloxane layer a base which may be of various materials. In a preferred process for preparing this printing plate, the base is an electrophotographic sheet which is given an electrostatic charge which serves as the means for attracting and holding the toner imposed on the polysiloxane layer until the toner image is fused onto the polysiloxane layer. In another modification an image of toner is imprinted on one base and then the toner image is superimposed and transferred to the organopolysiloxane coating and the toner fused to make it ink receptive.
摘要翻译：用于制备本文所述相同的印刷版和其制备方法包括适合于干法平版印刷的印刷版，其在非图像产生区域中具有拒油涂层，例如固化的弹性体有机聚硅氧烷，并且在所述油墨接受图像中产生相同固化的弹性体有机聚硅氧烷涂覆有熔融调色剂，并且在所述有机聚硅氧烷层下面具有可以是各种材料的基底。在制备该印版的优选方法中，基底是给予静电电荷的电子照相纸，其用作吸引和保持施加在聚硅氧烷层上的调色剂的装置，直到调色剂图像熔融在聚硅氧烷层上。在另一个改进方案中，调色剂的图像被印在一个基底上，然后将调色剂图像叠加并转移到有机聚硅氧烷涂层中，调色剂被熔化以使其具有接受墨水。
