摘要:
The present invention provides a recording solution for vaporization type heat transfer recording which produces no precipitate in a recording operation and thus no problem of burning in a vaporization portion.The recording solution for vaporization type heat transfer recording in which the recording solution is vaporized to be transferred to a recording material contains a dye, a solvent having a melting point of 0.degree. C. or less, and a compatibilier for increasing the solubility of the dye in the solvent. Particularly, when the temperature at which the weight loss by vaporization is 10% in thermogravimetric analysis at a rate of temperature rise of 20 C./min., is defined as the vaporization start temperature, the different between the vaporization start temperatures of any desired two of the dye, the solvent and the compatibilizer is set to 100.degree. C. or less.

Printing paper is provided which has a mixture layer including inorganic filler and hydrophobic resin formed on a piece of paper as a substrate for making a dye sprayed by vaporization or ablation adhere to the printing paper, and a printing method is provided which forms images on the printing paper by spraying a vaporized dye on the mixture layer without bringing the printing paper and the dye into contact with each other.
摘要:
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. Thus, it realizes a high resolution and a gradation within a picture element, produces high-quality images promptly, permits the printer to be made small and light, involves no waste materials, permits printing on plain paper, and needs a less amount of power and running cost.
摘要:
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.
摘要:
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.
摘要:
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 by heating, and then transferred to a recording medium disposed in an opposed relation to the transfer section, comprising:a dye represented by the general formula (I): ##STR1## where R.sup.1 and R.sup.2 are individually a substituted or unsubstituted alkyl or alkenyl group, or a cycloalkyl group, and when both R.sup.1 and R.sup.2 are unsubstituted alkyl groups, at least one of R.sup.1 and R.sup.2 is a branched alkyl group.
摘要:
During the recording where a liquid dye 22 supplied through a dye passage 27 is supplied to a vaporizing means 17 due to the capillarity of many small columns 21 within a vessel formed by coupling of a glass base 14 and a Teflon protection plate 290, the liquid dye in the vaporizing means is vaporized by irradiation of the laser beam L and the vaporized dye is transmitted to a photographic paper 50 passing a vaporization hole (aperture) 23 for the purpose of recording. The protection plate 290 has a critical surface tension against the liquid dye which is smaller than a surface tension of the liquid dye. Since the critical surface tension of the protection plate 290 is set smaller than a surface tension of the liquid dye, wettability of the liquid dye against the internal wall surface of the vaporizing hole 23 is low and the liquid dye left unvaporized at the vaporizing hole 17 at the time of recording is never deposited on the internal wall surface of the vaporizing hole. Therefore, the vaporizing hole is always kept clear, transfer of the vaporized dye 32 to the photographic paper is never prevented due to deposition of dye to the vapotizing hole and thereby excellent recording quality can always be guaranteed.

摘要:
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.
