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.

摘要: Both single-layer and multilayer imageable elements have a substrate and at least one imageable layer. The elements can be used to prepare either negative- or positive-working imaged elements, for example as lithographic printing plates. The imageable elements also include a radiation absorbing compound and a solvent-resistant polymer comprising pendant phosphoric acid groups, pendant adamantyl groups, or both. When this polymer comprises pendant adamantyl groups, they are connected to the polymer backbone through a urea or urethane group. The imageable elements have improved chemical resistance and thermal bakeability from the presence of the unique solvent-resistant polymer.

摘要: Positive-working imageable elements are prepared by providing a first layer and second layers onto a substrate. Both layers include the same or different radiation absorbing compounds dispersed within different polymeric binders. After both layers are dried, they are heat treated at from about 40 to about 90° C. for at least 4 hours under conditions that inhibit the removal of moisture from the dried first and second layers. This method of preparation provides elements with improved imaging speed and good shelf life.

摘要: Single-layer and multilayer imageable elements have a substrate and at least one imageable layer and can be used to prepare positive-working lithographic printing plates. The imageable elements also include a radiation absorbing compound and a solvent-resistant polymer binder comprising an —N(R)—C(═X)—N(R′)—S(═O)2— moiety that is attached to the polymer backbone, wherein X is O or S, R and R′ are independently hydrogen, halo, or an alkyl group having 1 to 6 carbon atoms. This solvent-resistant polymer binder is located in the imageable layer closest to the substrate and provides improved chemical resistance.
