In the method described in -1-, after the transfer material is pressure-bonded to the glass substrate and the base notebook is peeled off, the phosphor layer, the aluminum layer, and the peeling layer remain on the glass substrate. At this time, unnecessary organic components other than the release layer and the phosphor pigment of the phosphor layer remaining on the surface of the aluminum layer of the laminate transferred onto the glass substrate are removed by thermal decomposition treatment in the baking process. There is.

Problems to be Solved by the Invention However, in the transfer material having the structure described in 1-1, the above-mentioned transfer material is transferred onto the face plate and the glass dam plate, and then an aluminum layer (metal bank) is formed by a firing process. When sublimating unnecessary organic components other than the metal in the layer) and the phosphor pigment in the phosphor layer, such as the release layer and the binder resin in the phosphor, the percussion gas generated at this time partially sublimates the aluminum. There was a problem in that the aluminum layer was pushed or punched through and scattered, causing blisters, cracks, and pinholes in the aluminum layer.

Therefore, the first object of the present invention is to solve the above-mentioned problems, and to provide a phosphor film on the face plate of a cathode ray tube that is not rough and has excellent smoothness without blisters, cracks, or pinholes. An object of the present invention is to provide a transfer material for forming a fluorescent film that can be formed, a method for manufacturing the same, and a method for forming a fluorescent film using the transfer material.

Means for Solving the Problems In order to achieve the above object, the present invention is configured such that fine holes for degassing are formed in the metal hack layer.

That is, the transfer material for forming a fluorescent film according to the present invention is configured to include at least a metal back layer having micropores for degassing and a phosphor layer on a base film having a peeling layer.

In the above configuration, the phosphor layer can also be configured to include a carbon layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 20.

As shown in FIG. 1, the transfer t, I'l+ for forming a fluorescent film according to the present embodiment is provided with at least fine holes 4a for degassing in the spacer fifurno-311- having a peeling layer 2.
The metal back layer 4 having 4a, the phosphor layer 5, and the adhesive layer 6 are configured in any number of ways.

The transfer material 11 is manufactured as follows. That is, a release layer 2 is formed on the entire surface of the paste noilum I, a metal back layer 4 and a phosphor layer 5 are laminated on the entire surface, and then an adhesive layer 6 is formed on the entire surface. Thereafter, a large number of fine holes 4a for degassing are provided in the metal back layer 4 described in 1-1 by applying a laser beam to complete the transfer material 11.

As the base film 1, a film used as a base film for ordinary transfer materials, such as a plus deck film made of polyethylene terephthalate, polyester, polypropylene, polyethylene, nylon, or Cehalon, or a composite film of these and paper, is used. In order to impart releasability to the base film 1, it is preferable to apply a glue coating or a wax coat to the base film 1, or to provide a release layer 2 on the base film 1.

-1- The release layer 2 is made of thermoplastic resin, natural rubber, synthetic rubber, or the like, and is formed by a conventional printing method such as a gravure printing method, a screen printing method, or a roll coating method.

”-As the distribution light layer 5, ZnS:Ag or S is used as the phosphor.
nS: Cu, AI, Y, 0. S: A phosphor conventionally used in cathode ray tubes, such as Eu, is used, and an ink made of thermoplastic resin as a binder is used. As for the formation method, it is preferable to print by screen printing in consideration of the required film thickness and the particle size of the phosphor.

Since the phosphor layer 5 is formed on the base film 1 or the release layer 2, which has excellent smoothness, the surface on the base film I side also has excellent smoothness. In the case of a color cathode ray tube, the phosphor layer 5 may be formed by regularly arranging phosphors of three colors, red, blue, and green, in a stripe or dot shape so that they do not come into contact with each other.

”-As the distribution adhesive layer 6, the face plate 1 of the cathode ray tube is used.
・It is preferable to use a resin such as polyamide or acrylic with good adhesive properties as the glass material used for the heat-sensitive and pressure-sensitive adhesive layer. The formation method may be a conventional printing method such as a gravure printing method, a screen printing method, or a roll coat 1 method.

Further, the metal back layer 4 is a metal layer formed of a metal such as aluminum by a vacuum evaporation method, a sputtering method, an electron beam evaporation method, an ion blating method, or the like. The metal back layer 4 is formed between the phosphor layer 5 and the adhesive layer 6 when the cathode ray tube is a normal type (see Figure 13.16), and when the cathode ray tube is a flat type, the metal back layer 4 is formed between the phosphor layer 5 and the adhesive layer 6. If it is a visual type, it is formed between the base film 1 and the phosphor layer 5 (No. 1.4.7.1).
(See figure 0). Furthermore, when forming the metal back layer 4,
An anchor layer (not shown) may be formed if necessary to improve the adhesion of the metal back layer 4. The anchor layer may be an acrylic, rubber, urethane, polyamide, or vinyl resin that is used as an anchor layer in ordinary transfer materials.

Using the transfer material 11 having the layered structure described above, a fluorescent film IO is formed on the face plate 7'' of the cathode ray tube in the following manner.

As shown in FIG. 2, the transfer material 1.1 has its adhesive layer 6 superimposed on the face plate 7'' of the cathode ray tube.
The adhesive layer 6 is fused to the face plate 7 by heating and pressurizing. At this time, the temperature is 130~230℃, and the pressure is 3~
200 kg/cm' is suitable. Next, by peeling off the base film l, the release layer 2, metal back layer 4, and phosphor layer 5 are transferred onto the face plate 7,
Next, by firing, the release layer 2 is removed, and the binder resin and solvent that bond the fluorescent pigments in the phosphor layer 5 to each other are removed, and the fluorescent pigments are deposited on the face plate 7, as shown in FIG. A fluorescent film 10 consisting of a layer 8 mainly containing and the metal back layer 4 is formed.

In the post-transfer firing process, the organic gas generated in the core process, that is, the gas generated by sublimation of the release layer 2, binder resin, solvent, etc., smoothly escapes through the micropores 4a, causing blisters and cracks in the metal back layer 4. No pinholes or pinholes occur. The surface to which the laser beam is irradiated may be from either the base film surface or the phosphor surface, but it is better to apply the laser beam from the phosphor surface in terms of work efficiency.

The size and pinch of the fine ventilation holes 4a are preferably about 20 to 100 μm in diameter and 2 to 10 mm in pitch from the viewpoint of ventilation effect during firing, visual effect as a cathode ray tube, and laser work efficiency. The reason why the fine holes 4a are formed using a laser beam is as follows. In other words, it is necessary to make holes with a predetermined diameter at a predetermined position in at least the metal back layer 4 of the transfer material, but mechanical or chemical methods have low production efficiency and can produce holes so minute that they cannot be recognized with the naked eye. This is because it is impossible to drill holes. Therefore, according to the laser beam, the perforation position of the microhole 4a, the perforation strength,
Pore size can be easily controlled.

A more specific example of the above embodiment will be shown below.

A film thickness of I was printed on the entire surface of a polyester film with a thickness of 25 μm using an ink having the following composition I using a gravure printing method.
