Abstract: There is provided a hot-melt transfer ink image-receiving sheet which is excellent in abrasion resistance as well as image density and halftone dot reproducibility of a recorded image and useful as a contact printing film in the photomechanical process. In this hot-melt transfer ink image-receiving sheet 4 having an image-receiving surface 3 on a support 1, the image-receiving surface 3 has surface roughness (JIS-B0601) of 0.15-0.60 &mgr;m in terms of arithmetic mean deviation Ra and 1.0-3.0 &mgr;m in terms of 10-point height of irregularities Rz.

Abstract: There is provided a lithographic plate material with which a lithographic plate is prepared by the hot-melt transfer recording method utilizing an ink ribbon. The lithographic plate material has an image-receptive layer for hot-melt transfer recording that has a water retention property or can be imparted with a water retention property on a support, and the image-receptive layer has a surface roughness (JIS-B06011994) of 0.15 &mgr;m or more in terms of arithmetic mean deviation Ra and 1.00-3.00 &mgr;m in terms of 10-point height of irregularities Rz. It shows good transfer of the ink layer of ink ribbon and excellent fixation of the ink layer, and it enables production of a printing plate having excellent printing durability.

Abstract: There is provided a lithographic plate material which can be desensitized by distilled water or a fountain solution used for other lithographic plates, without desensitizing using an etching solution, and with less scumming in non-image portions of the print. The lithographic plate material has an image-receptive layer formed on a support and containing polyvinyl alcohol cross-linked by tetra alkoxy silane hydroxylate, titanium oxide microparticles, and silica having an average particle size of 1 nm to 100 nm. The image-receptive layer has a surface with an arithmetic mean roughness of not less than 0.40 &mgr;m and less than 1.20 &mgr;m, a contact angle of less than 50 degrees with distilled water at room temperature, and ink-receptiveness for hot-melt and lipophilic ink.

Abstract: There is provided a lithographic plate material which can be desensitized by distilled water or a fountain solution used for other lithographic plates without desensitizing process using an etching solution and lowers generation of scumming in non-image portion of printed matters. The lithographic plate material has an image-receptive layer formed on a support consisting of at least polyvinyl alcohol cross-linked by tetra alkoxy silane hydrolysate, titanium oxide micropatricles, silica having an average particle size of not less than 1 nm and less than 100 nm. The image-receptive layer has a surface having an arithmetic mean roughness of not less than 0.40 &mgr;m and less than 1.20 &mgr;m and a contact angle of less than 50 degree to distilled water at room temperature, and is ink-receptive for hot-melt and lipophilic ink.

Abstract: Disclosed herein are an image-forming material and a process for forming images, which can be applied to second originals used in the field of surveying.The image-forming material comprises a roughened plastics film substrate and a transparent resin layer, colored resin layer, photosensitive resin layer and protective layer formed one over another (in the order mentioned) on the roughened surface of the substrate, said four layers being so designed as un-exposed part thereof to be removed completely by dissolution or swelling during development after exposure to active rays. It permits the formation of a colored relief image without any dyeing step and gives rise to a good image free of base fogging without causing any decrease in printing sensitivity.
