    • There is provided a plate material for printing method based on wettability change. The plate material is comprised of a substrate and a recording layer including at least two polymers having a first polymer and a second polymer surrounding the first polymer. The first polymer has a changeable property of a receding contact angle and is comprised of a copolymer including perfluoroalkyl-containing acrylate or perfluoroalkyl-containing methacrylate. The second polymer has an oil-absorptive character defined as an area ratio determined in the specification and is comprised of a urethane polymer. The printing plate according to the present invention exhibits excellent ink-releasability and no toning during printing operation.
    • 提供了一种基于润湿性变化的印刷方法的板材。 板材由基材和包含至少两种具有第一聚合物的聚合物和围绕第一聚合物的第二聚合物组成的记录层组成。 第一聚合物具有后退接触角的可变性,并且包括含全氟烷基的丙烯酸酯或含全氟烷基的甲基丙烯酸酯的共聚物。 第二聚合物具有定义为说明书中确定的面积比并由氨基甲酸酯聚合物组成的吸油性。 根据本发明的印刷版在印刷操作期间表现出优异的油墨脱离性和无色调。
