摘要： A waterless or driographic printing plate which can be thermally imaged by an infrared laser is composed of a substrate; a thermal imaging layer containing a photothermal conversion material, such as an infrared absorbing material, and a thermoplastic polyurethane with pendent allyl groups; and a cross-linked silicone polymer top layer. It was discovered that when the imaging layer contains an allyl functional polyurethane mixed with an infrared absorbing dye or pigment, the polymeric layer will have enhanced solubility in certain solvents when exposed to infrared radiation. In addition, the polymeric layer continues to exhibit excellent adhesion to the silicone in unexposed areas so that the infrared absorbing layer can endure development with a suitable organic solvent, or a solvent mixture. Mild brushing or rubbing with the developing solvent readily removes laser-struck portions of the infrared imaging layer while unexposed areas remain firmly intact.

摘要： A lithographic imaging member, such as a printing plate, has a support having thereon and ink-accepting melanophilic layer and an ink-rejecting siloxane surface melanophobic layer. Within the printing plate is a photothermal conversion material capable of converting irradiation, such as IR radiation, to heat in exposed regions. Also within one of the layers is a compound that upon imaging releases a moiety that facilitates degradation of the surface melanophobic layer. The released moiety can be fluoride ion or a fluoride ion-containing compound. In some imaging members, a barrier layer may be interposed between the two other layers. Such imaging members can be digitally imaged and used for printing without post-imaging processing.

摘要： A method for making a lithographic printing plate comprising exposing a support, a melonophilic layer and a melonophobic layer, the latter containing crosslinked colloids to a laser beam having an intensity greater than 0.1 mW/ν2 for a time sufficient to give a total exposure of about 200 milliJoules/cm2 or greater. Good printing steps and long running plates are produced.

摘要： The present invention involves a method for making a relief image. A film that includes a carrier sheet and an imageable material is used to form a mask image that is opaque to a curing radiation. In one embodiment, the mask image is formed on the carrier sheet while in another embodiment, the mask image is formed on a receptor sheet. The mask image is then transferred to a photosensitive material, such as a flexographic printing plate precursor. The resulting assembly is exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. The carrier sheet or the receptor sheet may be removed from the mask image either before or after exposure to the curing radiation. Finally, the photosensitive material and mask image assembly is developed with a suitable developer to form a relief image.

摘要： A method for forming a printing plate from a printing plate precursor having a radiation-sensitive layer, sensitive to radiation in a first frequency region such as the far or near infrared, and to radiation in a second frequency region other than the first frequency region such as visible or ultraviolet. The plate is exposed twice. Once to imaging radiation in the first frequency region and again to radiation in the second frequency region. The second frequency region exposure is done only to the areas of the plate undesirably shaded during the imagewise exposure.

摘要： Negative working thermally imageable elements useful as lithographic printing plate precursors and methods for their use are disclosed. The elements have a substrate, a layer of imageable composition over the substrate and, optionally, an overcoat layer over the layer of imageable composition. The imageable composition has an allyl-functional polymeric binder. Optimum resolution and on-press performance can be attained without a post-exposure bake. The elements do not require a post-exposure bake and can be used in on-press development applications.
