本発明は、階調画像を得るための昇華性染料を用いた熱
転写方式において、ベースフィルムの不用な新しい記録
方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a new recording method that does not require a base film in a thermal transfer method using sublimable dyes for obtaining gradation images.
ビデオカメラ、磁気カメラ、テレビ、ビデオディスク等

として、熱転写印刷による再生技術がある。2. Description of the Related Art Techniques for reproducing two-dimensional images (hard copies) such as photographs from electrical one-dimensional time-series image signals obtained from video cameras, magnetic cameras, televisions, video disks, etc. are being actively researched. One of the leading technologies is the recycling technology using thermal transfer printing.

ーを製造するものである。Thermal transfer recording is a process in which an electrical signal containing image information is sent to a thermal disc in which 4 to 16 electric heating elements per IN are arranged in a row, and at the same time a "thermal transferable ink layer is coated on one side of a support sheet. A hard copy by pointillism is produced by moving a superimposed sheet of "gui sheet" and "image-receiving sheet" in contact with a head, thereby transferring ink from the "gui sheet" to the image-receiving sheet in dots.
しかしながら、この方法はサーマルヘッドとインキ層と
の間に支持体シートが存在するために熱伝導率が悪く、
そのためインキ中の昇華性染料が十分な量で受像シート
に転写されず、得られる画像は濃度が低くなる欠点があ
った。However, this method has poor thermal conductivity due to the presence of a support sheet between the thermal head and the ink layer.
Therefore, a sufficient amount of the sublimable dye in the ink is not transferred to the image-receiving sheet, resulting in the resulting image having a disadvantage of low density.
この欠点の解決のため、サーマルへラドの発熱体ドツト

間が長（なるという新たな欠点を生む。To solve this problem, it is possible to increase the amount of heat generated by the heating element dots of the thermal head or to reduce the speed at which the dots pass over the thermal head, but the former has a limit to the heat resistance of the thermal head. , which also creates a new drawback that power consumption increases accordingly, and the latter creates a new drawback that the transfer time becomes longer.
そのため本発明は、昇華性染料と磁性微粉末を溶解又は

。Therefore, in the present invention, an image receiving sheet is brought into direct contact with a sublimable dye-containing magnetic fluid in which a sublimable dye and magnetic fine powder are dissolved or dispersed, and the magnetic fluid is selectively heated by an electric image signal. A thermal transfer recording method is provided that is characterized by transferring a rising flower dye to an image-receiving sheet.
以下本発明の一実施例を図面を用いて説明する。 An embodiment of the present invention will be described below with reference to the drawings.

ない。The sublimable dyes used in the present invention include sublimable dyes used in conventional guisheets, such as anthraquinone-based, azo-based, methine-based dyes, and the like. When these dyes and magnetic fine particles such as magnetite, manganese zinc ferrite, etc. are dispersed in a solvent together with a dispersant, a sublimable dye-containing magnetic fluid 5 is obtained. This is installed near the heating element 2 in the thermal head base 1, and a gap is provided between the recording device upper plate 3 provided with the magnet 4 and the image receiving sheet 8 through which the recording device can be schematically constructed. Furthermore, the solvent and/or dispersant used in the sublimable dye-containing magnetic fluid are contained in the image receiving sheet 8.
Alternatively, since it is non-soluble and non-permeable to the surface of the image-receiving sheet provided with the dye-receiving layer, it does not cause background smudges in non-image areas.

When the image-receiving sheet 8 is fed into the recording apparatus by the paper feed roller 6 and passes through the heating element 2, when the electromagnet is energized, the sublimable dye-containing magnetic fluid 5 is transferred to the side of the upper plate 3 of the recording apparatus through the image-receiving sheet 8. attracted to.

マルヘッド基盤１等から供給、循環してもよい。When the heating element 2 is energized, the sublimable dye becomes a gas and is transferred to the image receiving sheet 8, thereby recording an image. The image-receiving sheet 8 recorded in this manner is discharged by a paper discharge roller 7 to obtain a hard copy. Note that the gap between the thermal head base 1 and the recording device upper plate 3 is preferably 10 μm or less, preferably 5 μm or less in addition to the thickness of the image receiving sheet.
Further, in order to obtain a stable recorded image density, the sublimable dye-containing magnetic fluid 5 may be supplied and circulated from the thermal head base 1 or the like using a supply device (not shown) or the like.

に供給すればカラー画像も可能となる。In this way, only the sublimable dye-containing magnetic fluid in contact with the image-receiving sheet is heated, so a high-density gradation image can be obtained at high speed. Moreover, unlike conventional die sheets, there is no consumption of base film, and color images can be produced by using three recording devices or by supplying three types of magnetic fluids containing dyes of the three primary colors in a pulsed manner.
上記のように本発明によれば、ベースフィルムが不用で

な装置の設計が可能となる。In addition, since the sublimable dye liquid can be attracted by an electromagnet, even if the relationship between the thermal head and the sublimable dye liquid is not vertical, it is possible to have a vertical horizontal relationship or other relationships, which makes it easier to design the device. This makes it possible to design a compact device.
