  公开（公告）日：2010-05-06

  A lithographic printing plate precursor is disclosed which comprises a support having a hydrophilic surface or which is provided with a hydrophilic layer, and a coating thereon, said coating comprising an IR absorbing agent and a contrast enhancing compound, characterized in that said contrast enhancing compound has the structure of formula (I). The printing plate comprising the contrast enhancing compound improves the thermoresponsivity of the coating and is capable of improving the resistance of the coating in the non-exposed areas against the alkaline developer.

  本发明公开了一种平版印刷版前体，其包括具有亲水表面或具有涂有亲水层的支撑体，并在其上涂层，所述涂层包括一个IR吸收剂和一个对比增强化合物，其特征在于所述对比增强化合物具有式（I）的结构。包含对比增强化合物的印刷版改善了涂层的热响应性，并能够改善未曝光区域的涂层对碱性显影剂的抵抗能力。
