    • A method for preparing a lithographic printing plate includes the steps of—providing a lithographic printing plate precursor including: a support having a hydrophilic surface or which is provided with a hydrophilic layer; and a coating provided on the support and including an image recording layer including hydrophobic thermoplastic polymer particles having an average particle size between about 40 nm and about 63 nm and a hydrophilic binder, the coating further including a pigment present in the image recording layer or in an additional layer of the coating, —image-wise exposing the coating, thereby inducing coalescence of the thermoplastic polymer particles at the exposed areas of the image recording layer; —developing the precursor by applying a gum solution to the coating, thereby removing the non-exposed areas of the image recording layer from the support; and—optionally, baking the developed precursor; wherein the hydrophobic thermoplastic polymer particles have an average particle size between about 40 nm and about 63 nm; the amount of the hydrophobic thermoplastic polymer particles is more than about 70% and less than about 85% by weight, relative to the image recording layers; and the pigment has a hydrophilic surface and provides a visible image after the image-wise exposing and developing with the gum solution. The lithographic printing plate precursor has an improved sensitivity, and the obtained lithographic printing plate exhibits an excellent clean-out, no toning, and a high printing run length.
    • 制备平版印刷版的方法包括以下步骤:提供平版印刷版前体,其包括:具有亲水性表面的或具有亲水层的载体; 以及涂层,其设置在所述载体上并且包括图像记录层,所述图像记录层包括平均粒度为约40nm至约63nm的疏水性热塑性聚合物颗粒和亲水性粘合剂,所述涂层还包含存在于所述图像记录层中或 另外一层涂层,以图像方式暴露涂层,从而在图像记录层的曝光区域引起热塑性聚合物颗粒的聚结; - 通过将胶溶液施加到涂层来开发前体,从而从支撑体去除图像记录层的未曝光区域; 和 - 任选地,烘烤显影的前体; 其中所述疏水性热塑性聚合物颗粒的平均粒度为约40nm至约63nm; 相对于图像记录层,疏水性热塑性聚合物颗粒的量大于约70重量%且小于约85重量% 并且颜料具有亲水表面,并且在用胶溶液进行成像曝光和显影之后提供可见图像。 平版印刷版原版具有提高的灵敏度,所得到的平版印刷版显示出优异的清洁,无色调和高打印行程长度。
