1, a transparent receiving layer 102 is formed on the upper surface of the photoreceptor 01, and a color image 103 for display is formed in the receiving layer 102 by a transfer method. The above metal substrate 10
For 1, a variety of metal plates such as aluminum, brass, and iron can be selected, and these are subjected to surface treatment such as plating or painting for the purpose of rust prevention or decoration. The receiving layer 102 is provided for the purpose of forming an image therein, and is formed by printing or painting using a resin such as a polyurethane resin, a polyester resin, an epoxy resin, or an acrylic resin. And
A color image 103 using a sublimable dye is formed in the receiving layer 102 by a transfer method described later. The receiving layer 102 has an ultraviolet absorber dispersed therein. Sublimation dyes have poor light fastness to ultraviolet light, and therefore, the light fastness is enhanced by dispersing an ultraviolet absorber.

される。A method of transferring and forming a color image 103 in the receiving layer 102 is performed by a method shown in FIG. That is, a metal substrate 101 on which a receiving layer 102 is formed is placed on a smoothly finished mounting member 111, and a transfer paper 112 on which a color image is formed by an ink jet printer using a sublimable dye ink. Is pressed, and the transfer paper 112 is pressed by the pressing tool 113 which has been smoothed under heating. In this way, the sublimable dye that forms a color image on the transfer paper is vaporized by heating, and the vaporized dye penetrates into the softened receiving layer 102 under pressure, and the receiving layer 102
A color image 103 of a vaporized sublimable dye is formed therein.

成される。Here, the heating temperature varies depending on the type of resin forming the receiving layer 102. For example, when a polyurethane resin is used, the heating is performed at a temperature of about 180 ° C. Generally, it is preferable to heat the resin around the softening point of the resin used. The applied pressure may be a pressure of about 10 g / cm 2 ,
By applying the pressure for about a minute, the dye penetrates to a considerably deep part of the receiving layer 102 and a beautiful color image 103 is formed.

のが良い。It is also important that the sublimable dye penetrates as deep as possible in the receiving layer 102. In that sense, the thickness of the receiving layer 102 must be at least 10 μm or more. If it is thinner than this, the dye that has penetrated easily comes off, and a beautiful color image cannot be retained forever. The thickness of the receiving layer 102 is generally 20 to 50 μm.
It is preferable to form it in the range of m. Further, the pressing force and the pressurizing time also affect the penetration depth. Since the pressing force and the pressurizing time have a relationship with each other, it is better to appropriately set an optimum place.

綺麗なカラー画像が形成できる。A color image formed on transfer paper using a sublimable dye ink is printed and formed by an ink jet printer. This color image can be selected from a variety of color images such as photographic images, paintings, other pattern images, and color images composed of one color on the entire screen. When a color image is printed using a magenta, yellow, cyan, or black sublimable dye ink with a printer of 1440 dpi, a very beautiful color image can be formed.

加圧を行うので転写紙の微小な凹凸の紙模様が受容層に

従来は転写後に再度表面研磨を施す必要がありコストを
高める要因になっていた。The color image is formed on the receiving layer by transferring the image by the above-mentioned method. However, the conventional method has the following problems. As a first problem, since pressure is applied to the transfer, the paper pattern with minute irregularities of the transfer paper is also transferred to the receiving layer, which impairs the appearance of the receiving layer. For this reason,
Conventionally, the surface must be polished again after the transfer, which has been a factor of increasing the cost.

どで形成するが、その表面になだらかな凹凸などが発生
して受容層膜厚に薄いところと厚いところが現れて加圧

画像ムラが発生する。The second problem is that the receiving layer is formed by a printing method or the like, but the surface of the receiving layer is gradually uneven and the thickness of the receiving layer becomes thinner and thicker. However, image unevenness occurs in a light portion and a dark portion in the transferred image.

程数も増えてコストを高める要因になっていた。As a third problem, since a color image on a transfer paper is formed by an ink jet printer, the image is composed of a collection of minute dot-like spots. If the dot-like spots are not sufficiently mixed with the sublimable dye even after the transfer, they may appear as dot-like marks on the receiving layer. In such a case, the appearance of the color image is greatly impaired. Conventionally, in order to eliminate this dot-like mark, under no pressure and at a temperature of 200 to 270 ° C.
Heat treatment for 15 minutes is performed to promote mixing of the dyes to eliminate dot-like marks. For this reason, the number of steps has been increased, which has been a factor of increasing costs.

れている。In FIG. 1, the display board 10 is placed on the article 111. This display plate 10 is formed by forming a receiving layer 12 on the upper surface of a metal substrate 11. The metal substrate 11 can be selected from various metal plates such as aluminum, brass, and iron, and has been subjected to surface treatment such as plating or painting for the purpose of rust prevention or decoration. The receiving layer 12 is formed by printing or painting using a paint in which an ultraviolet absorbent is dispersed in a polyurethane resin, a polyester resin, an epoxy resin, an acrylic resin, or the like. Further, the upper surface 12a of the receiving layer 12 is finished to a glossy and smooth surface by polishing.

A transparent film sheet 15 is sandwiched between the display panel 10 and the transfer paper 112. The film sheet 15 is made of a resin such as a polypropylene resin, a polyethylene resin, a polycarbonate resin, a nitrocellulose resin, a nitrofluorocarbon resin, and an acrylic resin, and has a glossy and smooth surface. The resin forming the film sheet 15 is not limited to the above resin, and any other resin having relatively high heat resistance can be selected. Note that a resin having water repellency, such as a fluorine-based resin, is not preferable. Also, this transparent film sheet 15
Those having a thickness in the range of 25 to 50 μm are selected.

5 and the transfer paper 112 are superimposed, and a transfer is performed by pressing with a pressing tool 113 under heating. The heating temperature and the pressing force may be the same as those in the conventional method, but it is better to apply the pressing time slightly longer. For example, 100 seconds has been performed in 90 seconds
It is better to set it slightly longer to about 110 seconds.

痕も現れない綺麗なカラー画像が得られる。By employing such a transfer method, a sublimable dye for forming a color image of transfer paper permeates the film sheet 15 and further permeates the receiving layer 12 to form a beautiful color image. 12 are formed. Then, a clear color image is obtained in which no paper pattern indentation of the transfer paper is generated on the upper surface of the receiving layer 12 on which the color image is formed, and no dot-like marks appear in the receiving layer 12.

に鮮明さが欠けてくる問題が生じる。Here, the thickness of the film sheet 15 has a great influence on the quality of the transferred color image, and as a result of various experiments, a thickness of 25 to 50 μm was found to be a suitable thickness range. If the thickness is less than 25 μm, the uneven paper pattern of the transfer paper reaches the receiving layer 12 and moves to the receiving layer. Also,
If the thickness is more than 50 μm, the dye remains in the film sheet 15, causing a problem that the color tone of the color image formed on the receiving layer 12 lacks sharpness.
