    • A method for the preparation of a lithographic printing plate comprises forming an oleophilic image on the surface of a hydrophilic support by depositing, preferably by ink-jetting, the desired image on the surface using an aqueous emulsion of an organic film-forming polymer which has been prepared by emulsion polymerization, whereby the polymer adheres to the surface of the printing plate forming an oleophilic film. The polymer preferably has functional groups such as sulphonate that bind the polymer to the hydrophilic surface. Preferably the polymer has a glass transition temperature of not greater than about 105° C. and where the glass transition temperature is above 50° C. the polymer, after deposition on the plate, is preferably subjected to a heat treatment to assist in film formation.
    • 制备平版印刷版的方法包括在亲水性载体的表面上形成亲油性图像,优选通过使用有机成膜聚合物的水性乳液沉积表面上所需的图像,所述有机成膜聚合物具有 通过乳液聚合制备,由此聚合物​​粘附到形成亲油膜的印版的表面。 聚合物优选具有将聚合物结合到亲水表面的官能团,例如磺酸盐。 优选地,聚合物的玻璃化转变温度不大于约105℃,并且其中玻璃化转变温度高于50℃。聚合物在沉积在板上之后优选经受热处理以辅助成膜 。

    • A method of producing a radiation-induced colorant transfer image on a support, includes the steps of: providing an image-receiving element comprising a support having thereon an image-receiving layer; providing a colorant donor element having a colorant transfer layer on a colorant element support and wherein colorant can be transferred from a transfer surface of the colorant donor element to the image-receiving element in response to selectively applied radiation; providing a uniformly reflecting opaque element that is sufficiently opaque to radiation at the wavelengths of the radiation source; causing the image-receiving element to be contacted with the colorant donor element and these elements to be positioned between the radiation source and the uniformly reflecting opaque element; and applying radiation to the colorant donor element to cause colorant to transfer to the image-receiving element.
    • 在支撑体上产生辐射诱导的着色剂转印图像的方法包括以下步骤:提供图像接收元件,该图像接收元件包括其上具有图像接收层的支撑件; 提供在着色剂元件支撑件上具有着色剂转移层的着色剂供体元件,并且其中可以响应于选择性施加的辐射将着色剂从着色剂供体元件的转移表面转移到图像接收元件; 提供对辐射源的波长处的辐射足够不透明的均匀反射的不透明元件; 使得图像接收元件与着色剂供体元件接触,并且这些元件将位于辐射源和均匀反射的不透明元件之间; 以及向着色剂供体元件施加辐射以使着色剂转移到图像接收元件。
