    摘要： An imaging member, such as a negative-working printing plate, can be prepared using a hydrophilic imaging layer comprised of a heat-sensitive hydrophilic polymer having a positively charged moiety, and optionally a photothermal conversion material. The heat-sensitive polymer has recurring units containing an N-alkylated aromatic heterocyclic group or an organoonium group that reacts to provide increased oleophilicity in areas exposed to energy that provides or generates heat. For example, heat can be supplied by laser irradiation in the IR region of the electromagnetic spectrum. Thus, the heat-sensitive polymer is considered "switchable" in response to heat, and provides an imaging means without wet processing.

    摘要翻译： 可以使用由具有带正电荷的部分的热敏亲水性聚合物和任选的光热转换材料构成的亲水性成像层来制备成像构件，例如负性印刷版。 热敏聚合物具有包含N-烷基化芳族杂环基团或有机基团的重复单元，其在暴露于提供或产生热量的能量的区域中反应以提供增加的亲油性。 例如，可以通过激光照射在电磁光谱的IR区域中提供热量。 因此，热敏聚合物被认为是响应热可“切换”的，并且提供了一种没有湿法处理的成像装置。
