    摘要： Embodiments of the present invention involve printing members that avoid ablation imaging mechanisms and, as a result, crosslinked topmost layers. Topmost layers as described herein exhibit good thermal stability and durability during printing, but can be cleaned (and thereby removed from unimaged areas) with water or aqueous cleaning fluids following imaging. It is found, in some embodiments, that the viability of certain topmost layers can be critically dependent on the nature of the underlying substrate, e.g., in terms of texture and/or surface volume.

    摘要翻译： 本发明的实施例涉及避免消融成像机构的打印部件，结果是交联的最上层。 如本文所述的最上层在印刷过程中表现出良好的热稳定性和耐久性，但是可以在成像后用水或含水清洁液清洁（从而从非成像区域除去）。 在一些实施方案中，发现某些最顶层的活力可能严重依赖于下层基质的性质，例如在织构和/或表面体积方面。

    摘要： The present invention includes an imageable element, which can be: (a) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; a polyvinyl acetal binder; and a sheet substrate; or (b) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; and a sheet substrate. The imaging layer includes a total aromatic diazonium salt containing compound content of at least 10 weight percent. The molar ratio of the aromatic diazonium salt containing compound having an alkoxy substituent to the aromatic diazonium salt containing compound that is free of an alkoxy substituent is from about 1.0:1 to 70:1. Upon imagewise exposure and development, an imaged element is obtained, which is mounted on a dry printing press containing lithographic ink and used to produce printed stock.
