    摘要: A plurality of negative-working lithographic printing plate precursors is provided in a stack. Each precursor comprises an aluminum-containing substrate having thereon a single imageable layer and an outermost topcoat that has a dry coating weight equal to or less than 1 g/m2. The non-imaging backside of the substrate is free of polymer coatings and has an average surface roughness (Ra) in both longitudinal and width directions greater than 0.15 μm. In addition, the imageable side of each underlying precursor is arranged in direct contact with the aluminum-containing substrate of the precursor above it without the use of an interleaf paper between the precursors.

    摘要: Positive-working imageable elements have a substrate and an imageable layer that can be used to prepare lithographic printing plates. The imageable elements also include a radiation absorbing compound, and a mixture of first and second polymers in the same imageable layer. The first polymer has two or more centered H-bonds (hydrogen bonds) within a non-covalently bonded unit, and the second polymer is a polyvinyl acetal. This mixture of polymers in the same imageable layer provides improved solvent resistance and processing latitude without a loss in imaging speed.
