メツシュを提供することにある。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for producing polyester mesh for screen printing, and its purpose is to prevent the strength of the mesh from decreasing and to improve its adhesion to photosensitive resin. The objective is to provide an improved mesh.

る。(Prior art) The screen printing method, which belongs to the perforated printing method, involves coating, exposing, and developing a photosensitive resin on a mesh-like fabric stretched over a frame.
In this method, a printing pattern is created by removing the unexposed area, and ink is passed through holes on the mesh from which the unexposed resin has been removed using urethane rubber, etc., to print on a predetermined printing material.

シュを用いたスクリーン印刷においてはこれが大きな問
題となっていた。However, since polyester has a highly smooth surface and low wood affinity, it has poor adhesion to photosensitive resins compared to other materials. For this reason, when a fine pattern is developed on polyester mesh, the pattern tends to peel off, and similar peeling also occurs when pressure is repeatedly applied to the pattern with a rubber called skeen to allow ink to pass through during printing. This has been a major problem in screen printing using polyester mesh.

て指摘されていた。In order to solve this problem, various chemical treatments, flame treatments, etc. have been used in the past, but satisfactory adhesion cannot be obtained, and instead problems such as a decrease in the strength of the mesh and breakage of the plate occur, resulting in external problems. It has also been pointed out that the mesh tends to break easily, for example when a corner of the printing material hits the mesh.
（発明の構成）
本発明者らはこのような問題点を改善すべく鋭意研究を
重ねた結果、これらの点が全て解決される方法を見出し
て本発明に到達した。(Structure of the Invention) As a result of intensive research aimed at improving these problems, the present inventors have found a method that solves all of these problems, and have arrived at the present invention.

法を要旨とするものである。That is, the present invention uses an inorganic gas with an ionization energy of -15 eV or more, a pressure of 0.001 to 10 torr, a high frequency power to the input electrode of 150 w-5/m2 or less, and an applied discharge energy of 10 to 1000. The gist of the present invention is a method for producing a mesh for screen printing, which is characterized by subjecting a polyester mesh to low-temperature plasma treatment under conditions of S/m2.

電極が冷却可能な構造を有していることが必要である。To explain this in detail below, in the low temperature plasma processing apparatus used in the present invention, the input side electrode is a metal electrode coated with an inorganic substance such as glass or ceramics, and the ground electrode is a metal body. It is necessary that the side electrode and the ground side electrode have a structure that allows them to be cooled.

をスクリーンメツシュとして、これを前記限定された条
件下で低温プラズマ処理するのである。In the method of the present invention, polyester filaments with a radius of 10 to 200 μm are woven into 10 to 500 meshes, and the screen mesh is finished through processes such as scouring and heat setting, and is woven at a low temperature under the above-mentioned limited conditions. It is treated with plasma.

。A method for performing low-temperature plasma treatment is to hold the mesh in a low-temperature plasma generator that can reduce the pressure, and to blow an inorganic gas under low pressure to the electrode, for example, at a frequency of KH.
This is done by applying high frequency power of 100 MHz to several hundred MHz. Note that in addition to the above-mentioned high frequency, low frequency, microwave, direct current, etc. can be used as the discharge frequency band.

い。There are no particular restrictions on the shape of the electrodes when carrying out the method of the present invention, and the input side electrode and the ground side electrode may have the same or different shapes, and various shapes such as a flat plate, ring shape, rod shape, cylinder shape, etc. are possible. However, it is preferable to use a type in which the metal inner wall of the processing equipment is grounded as one electrode.
Copper, iron, aluminum, etc. are generally used for the input side electrode, but in order to maintain stable discharge, it is preferable that the electrode be insulated coated with glass, enamel, ceramic, etc. with a withstand voltage of 10,000 V or more. A rod-shaped electrode is suitable for generating locally effective plasma. Furthermore, it is desirable that the electrodes have a structure that allows them to be cooled in order to prevent destruction and deterioration of the electrodes due to high voltage.

る。The electric power applied between the electrodes is not preferable because if it is too large, the object to be treated will decompose and deteriorate due to heat generation and the like, leading to a decrease in the strength of the mesh. From this point, the power applied between the electrodes is controlled to be less than 150 w/m'' per area of the positive electrode.

An inorganic gas with a voltage of 5 eV or less is not preferable because it tends to cause excessive etching on the mesh surface and reduces the strength of the mesh. Gas pressure during low temperature plasma treatment is 0.001~
10 torr, preferably 0.01 to 1 torr. 0.0
At a gas pressure of 0.01 torr or less or 10 torr or more, it becomes difficult to generate plasma, and the surface of the mesh is denatured due to abnormal discharge, generation of heat, etc., resulting in a decrease in the strength of the mesh.

、現像されスクリーン印刷用の版板となる。The polyester mesh for screen printing obtained by the present invention is stretched onto a printing frame according to a conventional method, and then a photosensitive resin is applied or a photosensitive film is pasted. Because it uses low-temperature plasma treatment under limited conditions, it has a high affinity with photosensitive materials and has excellent coating properties, eliminating pinholes in the coating film that are often seen when coating photosensitive emulsions on mesh. can be prevented. Furthermore, since the hydrophilicity of the mesh surface is improved even when a photosensitive film is attached, the mesh retains moisture well and allows the film to be applied uniformly. A mesh coated with or laminated with a photosensitive material is exposed to light using an appropriate light source and developed to become a plate for screen printing.

られなくなフた。The printing plate formed using the polyester mesh obtained according to the present invention has very good adhesion to the pattern, so that the solvent resistance and printing durability of the printing plate are significantly improved. Furthermore, since the mesh has increased wettability, it is also excellent in ink permeability. Therefore, it is suitable for printing with high viscosity ink such as graphic dot printing and paste printing, and there are no pinholes in solid printing.

After gauzing the mesh thus obtained by a conventional method, a photosensitive emulsion One-Pot Sol 50M (manufactured by Murakami Screen Co., Ltd.) was applied to a film thickness of nμ, and a 0.25 mm square mesh was coated with a mesh of about 1 mm. I burned it. Exposure conditions were 500 m using a high-pressure mercury lamp (manufactured by Oak Co., Ltd.) in step 4.
J/cm' exposure was performed. Apply Bakron Tape Y683 manufactured by Sumitomo 3M Ltd. to the gopan pattern obtained in this way, rub it strongly with your fingers, peel it off to the tape, record the number of gopans, and compare it with the plasma-untreated product. (Table 1). We also investigated the tensile properties of the mesh and its strength when the printing plate was torn (Table 2).
However, the plate used was a 56 cm square frame with zero outer dimensions, and the tension during the test was 1.2 to 1.3 using STG75B manufactured by Sun Giken Co., Ltd.
It was a+m.

), applied power was 50 Kw/m' (per positive electrode area), and irradiation energy was 250 Kw/m2. 1 under the same conditions as Example 1 using the mesh above.
I burned 10 CI11 square goban eyes. Silver Paste 5007 (DuPont Japan Limited) was printed on this printing plate, the weight of the printed matter was measured, and the ink permeability was evaluated. Note that the ionization energy of the neon gas used in the plasma treatment was approximately 21.6 eV from the mass spectrum, similar to Example 1.
