Zusammenfassung:	一种成像部件，可通过在一支撑板上施加热敏成像层制造，所述热敏成像层包含至少一种能从亲水性转变为疏水性或从疏水性转变为亲水性的热敏聚合物，与该转变有关的活化能Ea和阿仑尼乌斯指前因子A应满足下列关系：ln(A)≥0.4Ea+8.84；ln(A)≤1.69Ea-14.37。这种成像部件可用于无处理的热平版印刷。 An imaging member is composed of a hydrophilic imaging layer having a hydrophilic heat-sensitive polymer containing heat-activatable thiosulfate groups, and optionally a photothermal conversion material. Upon application of energy that generates heat, such as from IR irradiation, the polymer is crosslinked and rendered more hydrophobic. The exposed imaging member can be contacted with a lithographic printing ink and a fountain solution and used for printing with or without post-imaging wet processing. This imaging member is particularly useful for direct write imaging using IR lasers or thermal printing heads.
