    摘要: The present invention provides a thermal recording material having a thermosensitive layer comprising single phase diffuser polymer particles. Each of the diffuser polymer particles has a refractive index at the center thereof (RIcenter) different from a refractive index at the surface thereof (RIsurface), and a continuous refractive index gradient, sometimes referred to as GRIN technology. The diffuser polymer particles may have a RIcenter of from 1.46 to 1.61 and a particle size of 0.85 to 15 microns. Additionally, the thermal recording material of the present invention may also include heat deformable particles and a binder.The present invention also provides a method for providing an image by subjecting selected portions of a recording material such as that described above to a physical agent selected from the group consisting of heat, pressure, and combinations thereof, sufficient to reduce the opacity of said selected portions.

    摘要: 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.
