Abstract: A non-ablative negative-working imageable element has first and second polymeric layers under a crosslinked silicone rubber layer. These elements can be used in a simple method to provide lithographic printing plates useful for waterless printing (no fountain solution). Processing after imaging is relatively simple using either water or an aqueous solution containing very little organic solvent to remove the imaged regions. The crosslinked silicone rubber layer is ink-repelling and only the first layer that is closest to the substrate contains an infrared radiation absorbing compound to provide thermal sensitivity.

Abstract: Negative-working imageable elements can be imaged and processed to provide lithographic printing plates. These imageable elements are sensitive to infrared radiation but are insensitive to “white” light and thus can be more easily handled under white light conditions. These properties are possible by incorporating a filter dye having a λmax of from about 300 to about 500 nm into the imageable layer of the imageable elements.

Abstract translation: 可以对负面工作的可成像元件进行成像和处理以提供平版印刷版。 这些可成像元件对红外辐射敏感，但对“白”光不敏感，因此可以在白光条件下更容易处理。 通过将λmax为约300至约500nm的滤光染料掺入到可成像元件的可成像层中，这些性质是可能的。
