Heat sensitive non-ablatable wasteless imaging element for providing a lithographic printing plate with a difference in dye density between the image and non image areas
摘要：
According to the present invention there is provided a heat-sensitive non-ablatable wasteless imaging element for providing a lithographic printing plate, comprising on a support a top layer which is capable of forming by image-wise exposure image-wise hydrophobic and hydrophilic areas, characterized in that said imaging element contains an IR-dye capable of changing its optical density by exposure of the imaging element.
摘要（中）：

根据本发明，提供了一种用于提供平版印刷版的热敏不可消耗的无用成像元件，其包括在支撑件上的能够通过成像方式曝光成像的疏水和亲水区域形成的顶层， 其特征在于，所述成像元件包含能够通过成像元件的曝光来改变其光密度的IR染料。
