  • Patent number: 8092984
    Abstract: Negative lithographic printing plate having on a substrate a photosensitive layer comprising an alkaline soluble polymeric binder, an alkaline insoluble polymeric binder, a polymerizable monomer, and an initiator is described. The photosensitive layer is imagewise exposed with a radiation to cause hardening in the exposed areas, and then developed to remove the non-hardened areas. The combination of both alkaline soluble polymeric binder and alkaline insoluble polymeric binder in a photosensitive layer can give excellent combined durability, developability, and coatability.

  • Patent number: 8084189
    Abstract: A method of making imaged elements such as lithographic printing plates is achieved by imagewise exposing an infrared radiation-sensitive positive-working imageable element to provide exposed and non-exposed regions. The imaged element is developed using a single processing solution having a pH of from about 9 to about 11.5 and containing carbonate ion and at least 1 weight % of one or more anionic surfactants, to remove predominantly only the exposed regions to provide an image and to provide a protective coating on the imaged surface. The imageable element comprises a substrate and a radiation absorbing compound, and has an imageable layer on the substrate that comprises a developability-enhancing compound and a poly(vinyl acetal) in which at least 25 mol % of its recurring units comprise pendant nitro-substituted phenolic groups.

  • Patent number: 8034538
    Abstract: Negative-working imageable element can be used to prepared lithographic printing plates. These elements include a water-soluble contrast dye having a ?max in the range of from about 450 to about 750 nm and having an absorption that is lower than 10% with respect to the absorption of the radiation absorbing compound in the element at the wavelength used for exposure. The contrast dye is present in sufficient H-aggregation such that less than 40% of the entire absorption spectrum from the contrast dye is contributed by it in non-H-aggregated form.
