Abstract: A printing paper for use in sublimation-type thermal transfer recording includes a sheet-like base and a dye receiving layer disposed thereon. The dye receiving layer is composed of a copolymer of substituted or unsubstituted phenoxypolyethylene glycol acrylate or substituted or unsubstituted phenoxypolyethylene glycol methacrylate and another monomer. The substituted or unsubstituted phenoxypolyethylene glycol acrylate or the substituted or unsubstituted phenoxypolyethylene glycol methacrylate is of a proportion of at least 50 weight % of the copolymer.

Abstract: Disclosed herein is a method for recovering binder resin from the ink layer of ink ribbon, said method comprising collecting ink ribbon having an ink layer consisting of dye and binder resin, dissolving the ink layer of ink ribbon in a solvent in which dye and binder resin are soluble, freeing the resulting solution of insoluble matter, concentrating the solution, pouring the resulting concentrate into a solvent in which dye is soluble but binder resin is substantially insoluble, thereby precipitating binder resin, and separating and drying precipitates. By concentrating the solution remaining after precipitation of binder resin and drying the concentrate, it is possible to recover dye. Disclosed also herein is an apparatus for recovering dye and binder resin according to said method.

Abstract: Disclosed is Printing paper which incorporates a sheet substrate and a dye-receiving layer wherein the dye-receiving layer contains a vinylphenolic resin and a dyeable resin or contains a polymer of a vinylphenolic resin, a butyral resin and a poly-functional isocyanate. The printing paper is used in thermal sublimation transfer recording and gives an image with improved storing characteristics in terms of the light resistance, dark fading resistance, sebum resistance, plasticizer resistance, etc.

Abstract: An ink sheet (3) is wound around rollers (6), and a recording sheet (4) is placed with a space (d) between the ink sheet (3) and the recording sheet (4) and is advanced. The thickness of the space (d) is a value in the range of 1 to 100 .mu.m. The ink sheet (3) is irradiated with a laser beam (L) emitted by a laser (5) to transfer the dye contained in a dye layer formed on the ink sheet (3) from the ink sheet (3) to the recording sheet (4) for printing. The dye layer of the ink sheet (3) is replenished with the dye (30, 30A) heated and fused by a heater (9) by a dye supply unit (7) at a position other than a position where the ink sheet (3) is irradiated with the laser beam (L). Since the ink sheet and the recording sheet are held with the space (d) having a thickness in the range of 1 to 100 .mu.m, the dye once transferred to the recording sheet is not transferred from the recording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed.

Abstract: The recording apparatus of the present invention comprises a recording part in which a layer of a heat-fusible recording material is formed opposite a recording medium with a gap between, the recording part being so constructed as to selectively heat said heat-fusible recording material, thereby vaporizing or ablating it, and transfer the vapor to the recording medium through the gap, the recording material containing a heat energy absorber which promotes the heating of the recording material.
