    摘要： Object: A method for preparing a lithographic printing plate directly from digital image signals with the use of a presensitized lithographic printing plate comprising a support having thereon a photosensitive layer and a light-shielding layer which can be removed imagewise with laser light is provided, wherein the light-shielding layer, which can be industrially produced readily at a moderate price can be removed sufficiently during a process of development without the need of removing a masking layer at an unexposed portion and adverse effect on a photosensitive layer.Constitution: A lithographic printing plate can be obtained by making use of a presensitized lithographic printing plate comprising a support having thereon a photosensitive layer containing o-quinonediazide compound, photo-degradable or photo-polymerizable resin and water-soluble resin and a light-shielding layer containing an infrared absorbing material and a material capable of absorbing the photosensitive wavelength of the photosensitive layer and by a process comprising ablating imagewise the light-shielding layer with laser light, overall-exposing with a ray active to the photosensitive layer to cause photochemical change of the photosensitive layer in which the light-shielding layer has been removed by ablation (e.g., making alkali-soluble) and dissolving out the photosensitive layer at a non-imaging area.

    摘要： A process for image forming by heat transfer method is disclosed. The process comprises the steps of (1) transferring an ink image from an ink layer of an ink sheet, which comprises a support and an ink layer provided on the support, to a surface of an intermediate image receiving layer of an intermediate image receiving sheet, which comprises a support and an image receiving layer provided on the support, by imagewise heating the ink layer, and (2) re-transferring the ink image transferred on the intermediate image receiving layer to a secondary image receiving sheet,In the above process, the ink layer comprises a coloring material and a homopolymer or a copolymer comprising a repeating unit derived from a monomer represented by the following Formula 1 or a phthalic polyester formed by polymerization of phthalic acid and a polyol; ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms; R.sub.2, R.sub.3 and R.sub.4 are each a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or a --COOR.sub.5 group, R.sub.5 a hydrogen atom or an alkyl group having 1 to 12 carbon atoms.
