Slip sheet for a planographic printing plate, production process thereof and a protected planographic printing plate and laminate thereof
摘要：
The present invention provides a slip sheet that protects a planographic printing plate in which the coefficient of static friction between corresponding surfaces of the slip sheet that contact an image-forming surface of the planographic printing plate is 0.35 or less, the surface strength of the slip sheet is 15 or more, or the Clark stiffness of the slip sheet is 20 to 50. In a production process of the planographic printing plate, the image-forming surface and the slip sheet are adhered by suitably charging, and following their lamination, the charge rapidly dissipates resulting in favorable separation, discharge characteristics and storage characteristics in an automatic plate feeder. In addition, sticking between the slip sheet and the image-forming surface during heat treatment can also be prevented simultaneously. This slip sheet is particularly effective for planographic printing plates of the heat mode type and photon mode type on which images are formed by exposure to laser light.
摘要（中）：

本发明提供了一种保护平版印刷版的滑动片，其中与平版印刷版的图像形成表面接触的滑动片的相应表面之间的静摩擦系数为0.35以下，滑动面的表面强度 片材为15个以上，或者滑片的克拉克刚度为20〜50个。在平版印刷版的制造工序中，成像面和滑片通过适当的充电而粘合，并且在其层压之后， 电荷迅速消散，导致自动送片器中的良好的分离，放电特性和存储特性。 此外，也可以同时防止在热处理期间在滑动片和成像表面之间的粘附。 该滑片对于通过暴露于激光形成图像的热模式型和光子模式型的平版印刷版特别有效。
