図で説明した方法と同じ欠点を有する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a metal mask screen plate that allows highly accurate printing. The conventional method for manufacturing a metal mask screen plate is as shown in FIG.
In this method, the printed pattern 3b is formed by bringing the two parts into close contact with each other and applying metal plating 6 between the two parts 1 and 5, thereby manufacturing a metal mask screen plate. Since the method shown in Fig. 1 uses electroplating, the amount and properties of deposited metal vary depending on conditions such as plating liquid composition, liquid temperature, and electric current, making control very difficult.
After the mesh screen 5 and the metal foil 1 are completely brought into close contact with each other, the mesh screen 5 and the metal foil 1 must be attached by metal plating, and must be careful not to touch the etched surface of the metal foil 1. Therefore, workability is reduced. bad.
In addition, in the above-mentioned screen plate, the opening is small because the mesh 6 is attached to the mesh screen 5, and the reproducibility of the pattern during printing is poor.
If the plate is made repeatedly, the mesh screen 5 and the metal foil 1 cannot be separated. Therefore, it cannot be reprinted and has poor medicinal properties. In addition, low melting point metals (solder,
After applying Pb, Sn), the metal foil is placed in close contact with this mesh screen, and the low melting point metal is melted by heat, and the metal foil is fixed in contact with the mesh screen.
Thereafter, the first method was to create a screen plate by creating a printing pattern on metal foil using the photoetching method.
It has the same drawbacks as the method described in the figure.

版である。 The manufacturing method according to the present invention will be explained below with reference to the drawings. First, as shown in FIG. 2, a photoresist is applied onto the metal foil 1, and then a resist pattern 3a is formed on the surface of the metal foil 1 using a known photolithography technique.
On the other hand, as shown in FIG. 3, a water-soluble photosensitive emulsion 4 is coated on a mesh screen 5. This water-soluble photosensitive emulsion 4 is a mixture of PVA (polyvinyl alcohol).
It is a mixture of photosensitive substrates such as hexavalent chromium salts, ferric salts, diazonium salts, etc., and gelatin. Next, as shown in FIG. 4, a water-soluble photosensitive emulsion 4 is applied to the mesh screen 5 in a dark room, and then immediately attached to the metal foil 1, and temporarily attached by drying with cold air. Thereafter, etching is performed on the resist surface of the metal foil 1 until the water-soluble photosensitive emulsion 4 is exposed, thereby forming a printed pattern 3b. Next, as shown in FIG. 5, the water-soluble photosensitive emulsion 4 located on the printed pattern 3b on one side of the metal foil is dissolved by spraying water from the direction of the first side of the metal foil to form a printed pattern 3c. Thereafter, the water-soluble photosensitive emulsion surface 4 is exposed to light and cured, thereby completely adhering the metal foil 1 and the mesh screen 5. Next, the photoresist 2 on the metal foil surface 1 is removed using an organic solvent. Figure 6 shows a metal mask screen plate completed through the steps described above.

A water-soluble photosensitive emulsion mixed at a ratio of 1%, 89%, and 1% is applied to a thickness of about 50 μm using a bucket. The metal foil thus treated and the mesh screen are brought into close contact with each other and tacked together by drying with cold air. Next, etching is performed from the resist surface of the metal foil to form a printed pattern. Next, as shown in Figure 4, water is sprayed in the form of a mist under a water pressure of 1.5 kg/cm 2 from the direction of the metal foil, dissolving the water-soluble photosensitive emulsion only in the printed pattern area and changing the printed pattern on the metal foil surface. Form. Next, as shown in FIG. 5, the surface of the water-soluble emulsion is exposed to ultraviolet light and cured, thereby completely adhering the metal foil and mesh screen. Furthermore, the photoresist is peeled off using an organic solvent such as acetone to complete the process as shown in FIG.

Since the water spray is applied to the soluble photosensitive emulsion, the metal foil acts as a mask and only the water-soluble photosensitive emulsion in the printed pattern area is dissolved and removed. You can create a printing pattern of
The metal mask screen plate can be manufactured easily and in a short time, and as shown in Fig. 7,
Very small patterns of numbers such as 0, 6, 8 and alpha alphabets such as A, B, P, Q (0.3mm x 0.3mm)
