    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: The recording apparatus of the present invention comprises a recording part in which a layer of a heat-fusible recording material (12) is formed opposite a recording medium (50) with a gap (d) between, the recording part being so constructed as to selectively heat said heat-fusible recording material (12), thereby vaporizing or ablating it, and transfer the vapor to the recording medium through the gap (d), the recording material containing a heat energy absorber which promotes the heating of the recording material. The invention should preferably be modified such that the recording material contains uniformly dissolved therein a light-heat converting dye which, upon irradiation with light, absorbs the light of specific wavelength and heats the recording dye. The recording apparatus should preferably have a semiconductor (18) to emit laser as an energy source to selectively vaporize or ablate the recording material, and a means to continuously feed the recording medium (50) to the recording part, the recording medium having an image receiving layer (50a) which faces, with a gap between, the layer of the recording material in the recording part. The recording dye should preferably contain uniformly dissolved therein a light-heat converting polymeric material which has in the main chains or side chains, or at the terminals a dye segment capable of absorbing the light of specific wavelength which is irradiated to heat the recording dye. This prevents the vaporization of the dye component capable of absorbing light. The invention may be modified such that the recording material contains a light-heat converting pigment capable of absorbing the light of specific wavelength irradiated for heating, said pigment being surface-treated for improved dispersion into the recording material. According to the present invention, it is desirable that at least one of the light-heat converting dye, light-heat converting polymeric material, and light-heat converting pigment be in the state of uniform segregation at the interface between the layer of the recording material and the gap. The present invention is embodied also in a recording method which comprises transferring the recording material to the recording medium by using the recording apparatus. The present invention provides a recording apparatus and recording method assured of high-quality recording with high thermal efficiency, facilitating the reduction in size and in weight, freed of wastes such as used ink sheet.

    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 rcording sheet to the ink sheet, so that a clear picture having a comparatively high density can be printed. Since the dye layer of the ink sheet is replenished with the dye, the ink sheet can be repeatedly used, so that no waste is produced.
