Abstract: A recording method of ink jet system which employs a recording solution composed of a dye which vaporizes more than 90 wt % upon heating at a temperature above 300.degree. C., leaving residues in an amount less than 10 wt %, and a solvent having a boiling point higher than 150.degree. C. which dissolves or disperses the dye more than 5 wt % at a temperature below 50.degree. C., the recording solution being heated at the time of recording by the recording solution heating unit which has a porous structure formed thereon which is composed of fine parts whose dimension in the plane direction is 0.2-3 .mu.m and whose dimension in the direction perpendicular to the plane direction is 2-15 .mu.m. This recording method makes use of the advantage of both the thermal transfer system and the ink jet system.

Abstract: A recording head and a recording apparatus using this recording head with which while exploiting the merits of an ink-vaporizing laser beam printer it is also possible to maintain good performance during repeated ink transfer. In a printer head 40 and a printer 81 which vaporize a recording substance 22 and transfer it onto a body to be recorded on 50, the radius of the circle having as its circumference the overall length of the inner periphery of an aperture 33 for discharging vaporized recording substance 32 to the body to be recorded on 50 side is 5 .mu.m to 300 .mu.

Abstract: A recording unit structure comprising a recording material layer faced to a recording body with a space incorporated therebetween, so that said recording material is vaporized and transferred to said recording body through said space, provided that pores are provided to a vaporizing portion of the recording material in such a manner that the pores be present within the layer of the recording material. The recording unit structure of the present invention assures a recording of excellent quality, is made compact and light weight, yields a high thermal efficiency, and produces no used ink sheets and other wastes. The present invention also relates to a recording device comprising the same.

Abstract: A thermal transfer recording material for use in a recording apparatus in which the thermal transfer recording material is introduced into a transfer section having a porous structure by an effect of capillarity, subjected to a state transformation such as vaporization or droplet formation by heating, and then transferred to a recording medium disposed opposed to the transfer section, comprising:a dye having a molecular weight of 400 or less and represented by the general formula (I): ##STR1## where A is a substituted or unsubstituted p-phenylene group, R.sup.1 and R.sup.2 are individually a hydrogen atom, a substituted or unsubstituted alkyl or alkenyl group, a cycloalkyl group or a substituted or unsubstituted phenyl group; and R.sup.1 may constitute a heterocyclic group composed of a five- or six-member ring in combination with the p-phenylene group A and a nitrogen atom adjacent to the p-phenylene group A, or another heterocyclic group composed of a five- or six-member ring in combination with R.sup.

C. or lower and represented by the general formula (I): ##STR1## where A is a substituted or unsubstituted p-phenylene group, R.sup.1 and R.sup.2 are individually a hydrogen atom, a substituted or unsubstituted alkyl or alkenyl group, a cycloalkyl group or a substituted or unsubstituted phenyl group; and R.sup.

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.

Abstract: A method and apparatus for regenerating a thermosensitive transfer recording medium 1 comprising a dye layer having a thermally diffusable dye at a concentration, wherein the medium 1 is superposed on a material 10 to be transferred and heated in an imagewise pattern to transfer the dye of the medium 1 to the material 10 to be transferred thereby forming an image. The apparatus comprises a dye supplier 4 containing a thermally diffusable dye at a concentration higher than that of the dye layer, and a heating means 7 for diffusing the dye from the supplier 4 toward the dye layer whereby the dye consumed during the transfer recording operations is supplemented from the supplier 4 to the dye layer. A thermosensitive transfer recording apparatus is also described along with a thermosensitive transfer recording medium and a dye supplier.
