Abstract
Official abstract text for this publication.
Positive-working lithographic printing plate precursors have an inner layer that includes a polymeric binder having an acid number of at least 30 mg KOH/g of polymer to and including 150 mg KOH/g of polymer, at least 3 weight % of recurring units derived from one or more N-alkoxymethyl(alkyl)acrylamides or alkoxymethyl(alkyl)acrylates, at least 2 weight % of recurring units having pendant 1H-tetrazole groups, and at least 10 weight % of recurring units having pendant cyano groups. The use of such polymeric binders in the inner layer provides good bakeability and chemical solvent resistance. Such positive-working lithographic printing plate precursors also include an outer layer disposed over the inner layer, which outer layer comprises an infrared radiation absorbing compound.
First claim
Opening claim text (preview).
The invention claimed is: 1. A positive-working lithographic printing plate precursor comprising: a substrate, an imageable layer that is an inner layer disposed on the substrate, the imageable layer comprising a polymeric binder having an acid number of at least 30 mg KOH/g of polymer to and including 150 mg KOH/g of polymer, the polymeric binder comprising, in random order, at least 3 weight % of recurring units derived from one or more N-alkoxymethyl (alkyl)acrylamides or alk…
