    摘要: A positive-working multi-layer lithographic printing plate precursor has an inner imageable layer disposed over a substrate. This inner imageable layer comprises one or more first polymeric binders that are present in a total amount of at least 50 weight % and up to and including 97 weight %, based on total inner imageable layer dry weight. The precursor also has an ink-receptive outer imageable layer disposed over the inner imageable layer and this ink-receptive outer imageable layer comprises one or more second polymeric binders that are different than the first polymeric binder. Each of the one or more first polymeric binders has a weight average molecular weight of at least 200,000 and can also have a polydispersity of at least 4.

    摘要: A thermally-sensitive, positive-working lithographic printing plate precursor can be used to prepare lithographic printing plates using high pH, silicate-free processing solutions. The precursor has a grained an anodized aluminum-containing substrate including a poly(vinyl phosphonic acid) interlayer. A first ink receptive layer, and optionally a second ink receptive layer, is disposed directly on the poly(vinyl phosphonic acid) interlayer. This first ink receptive layer comprises an aromatic acid dye that comprises at least two aromatic groups in an amount of least 0.5 weight %. In addition, the precursor comprises an infrared radiation absorber in one of the layers.

    摘要: Lithographic printing plate precursors can have an imageable 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 provides good bakeability and chemical solvent resistance, especially for positive-working precursors.
