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.

摘要： Imageable elements that contain silicate-coated polymer particles in the imageable layer, stacks of these elements, and methods for forming images using these elements are disclosed. The elements do not stick to each other when stacked without interleaving paper, and only one imageable element is lifted at a time when the imageable elements are handled by automatic processing equipment. Blanket piling is not observed when silicate-coated particles are present in the imageable layer.

摘要： The present invention relates to printing plate coating compositions comprising: (a) a carbon pigment dispersible in water; (b) at least one polymer comprising at least one ionomeric polymer subunit; and (c) at least one high molecular weight thickening agent which shows pseudoplastic behavior. The printing plate precursor of this invention is prepared by coating a printing plate substrate with the coating composition.

摘要： A positive-working lithographic printing plate is used to provide a positive image without a post-exposure baking step and without any floodwise exposure steps. The printing plate includes a layer that is imageable using an infrared radiation laser. This layer consists essentially of a phenolic resin, an infrared radiation absorbing compound, and a dissolution inhibitor that is non-photosensitive and is capable of providing sites for hydrogen bonding with the phenolic moieties of the binder resin. These printing plates are developed with an alkaline composition that includes an alkali metal silicate, a thickener and a fluorosurfactant or phosphate ester hydrotrope.
