Abstract

To obtain an operation panel for a capacitance switch capable of clearly displaying a translucent display pattern without leaking light from a shaded part, and preventing that malfunction and non-function are caused in the capacitance switch.

Field of the Invention The present invention relates to a coated panel, a finishing operation panel, and a method of manufacturing the same, for example, for producing an operation panel of an electronic device such as a mobile phone or a digital music player. [Prior Art] As a display panel used for an electrochemical product or the like, a light is emitted from a light source such as an LED provided on the back surface of the panel to display a pattern on the surface of the panel. Such a display panel can be formed using one of the coated sheets, that is, the transfer sheet 101. As shown in Fig. 7, the display surface formed by the transfer sheet 1 () 1 is used, and 111 is provided on the surface of the resin molded article 1 () 9 at least with a light transmitting portion 103 for forming a pattern and shielding. The portion 1〇4' also has a peeling layer 1〇5, a finishing layer 106, and an adhesive layer 1〇7. Since the panel 111 is formed such that the light irradiated on the back surface of the panel passes through the light transmitting portion 103 but does not pass through the light blocking portion m, it is formed on the surface of the panel. Therefore, the light shielding portion 104 must have a shielding property of completely concealing light. The light-shielding portion 104 can use black ink in order to effectively block light. Moreover, in terms of design, there are many cases where the operation panel is black. When the display film m is used, the thickness of the light-shielding portion 1〇4 is usually several (four) when the display film m is formed by gravure printing. Therefore, when the light-shielding portion 1〇4 is formed, it is necessary to use high light-shielding property. Ink. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 7-84533. SUMMARY OF THE INVENTION Problems to be Solved by the Invention In recent years, in an electronic device such as a mobile phone or a digital music player, it is mounted inside. The number of wheeled devices called electrostatic capacity switches has increased. The so-called electrostatic capacity switch ' is a switch that uses a change in the electrostatic capacity of the electrode when the finger approaches the electrode.

Composition. Further, in the above invention, the light shielding portion is preferably formed by laminating two or more layers of insulating black ink by gravure printing. The method for producing a finishing operation panel according to the present invention is characterized in that the coated sheet formed by any of the above-described structures is placed in a mold so that the surface of the base sheet on which the light-shielding portion is not formed faces the cavity. The shaped tree® grease flows into the mold, and after cooling and solidifying, the base sheet is peeled off from the coated sheet. In the method for producing a decorative operation panel of the present invention, the coated sheet and the resin molded article obtained by any of the above-described configurations are bonded together by an adhesive. In the finishing operation panel of the present invention, a light-transmitting portion for forming a light-transmitting display pattern and a light-shielding portion are formed on the surface of the resin molded article, and the light-shielding portion is formed of an insulating black ink. Further, in the above-mentioned painted panel, the series equivalent resistance value (ESR) measured by the LCR meter between the switch touch surfaces of the two places adjacent to the surface of the light-transmitting display pattern 201014502 is preferably ΐ〇ΜΩ. the above. The electronic device of the present invention comprises a capacitance switch and a finishing operation panel provided to face the capacitance switch, and the coating operation panel has a resin molded article and a surface formed on the surface of the resin molded article. The light-transmitting display pattern is formed by the light-transmitting portion and the light-shielding portion, and the light-shielding portion is formed of an insulating black ink. EFFECTS OF THE INVENTION According to the coated panel of the present invention, since the light-shielding portion is formed of an insulating black ink, light is not leaked from the light-shielding portion, and the light-transmitting display pattern can be clearly displayed. According to the finishing operation panel using the coated sheet of the present invention, an operation panel in which the electrostatic capacity switch does not malfunction or does not operate can be obtained. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, a coated sheet for forming an electrostatic capacity switch operation panel used in the present invention will be described. In the first drawing, the above-mentioned coated sheet is used for the sheet of the surface of the (4) resin molded article, and for example, the transfer sheet 1 can be used. The transfer sheet i is formed with at least the transfer layer 8 on the sheet 2 (the lower side of the base sheet 2 in the drawing) is formed as a light transmission, and the light shielding portion 4 is provided. The light transmissive portion 3 surrounded. 201014502 The transfer molding sheet 9 is melted on the resin molded article 9 at the same time as the molding of the resin molded article 9 by the simultaneous molding transfer method shown in Fig. 2(a), and is peeled off after demolding. In the base sheet 2 of the transfer sheet 1, as shown in Fig. 2(b), the transfer layer 8 of the transfer sheet 1 can be transferred to the surface ' of the resin molded article 9 to form a capacitance switch operation. panel. Further, the simultaneous transfer printing method will be described later. As the base sheet 2, a polyester resin, a polypropylene resin, a gas vinyl resin, a polyethylene resin, a polyethylene terephthalate resin, a polycarbonate resin, a nylon resin, a vinylon resin, or the like can be used. A plastic sheet such as an acetate resin, a polyethylene resin, a polyamide resin, a polyacryl resin, or a polyethylene resin. The thickness of the base sheet 2 is 1 〇 to 1 〇〇 #m. The base sheet 2 can also be used with a peeling property itself. Further, in order to make the peeling property more stable, a release layer can be formed between the transfer layer 8. The release layer is a φ layer which is removed together with the base sheet 2 after the transfer step. Further, a curable resin such as polyoxymethylene resin, melamine resin, alkyd resin or epoxy resin can be used as the material of the layer. Examples of the method for forming the release layer include a coating method such as a roll coating method or a spray coating method, and a printing method such as a gravure printing method, a screen printing method. In order to more reliably perform the peeling from the base sheet 2 or the above-mentioned release layer, the peeling layer 5 may be formed between the coating layer 6 and the coating layer 6. The J-separated layer 5 is peeled off from the base sheet 9 + u or the release layer while being peeled off from the base sheet 2, and remains on the transfer layer 6 side, forming 7 201014502 as a transfer object. The outermost layer. The material of the peeling layer 5 can be an acrylic resin, a polyester resin, a polystyrene resin, a cellulose resin, a rubber resin, a polyurethane resin, a polyvinyl acetate resin, or the like. a copolymer of vinyl acetate vinegar copolymer resin or ethylene-vinyl acetate copolymer resin. When the peeling layer 5 is required to have a hardness, a photocurable resin such as an ultraviolet curable resin, a radiation curable resin such as an electron beam curable resin, or a thermosetting resin can be used. As a method of forming the release layer 5, there are a coating method such as a gravure roll coating method, a roll coating method, a stretch roll coating method, or a gravure printing method, a screen printing method, or the like. A coating layer 6 may be added to the transfer layer 8 for imparting pattern design. The material of the coating layer 6 can be a polyethylene resin, a polyamide resin, a polyester resin, an acrylic resin, a polyurethane resin, a polyvinyl acetate resin, or a polyacetamide. A resin such as a formic acid I-based resin, a woven cellulose, or a resin such as an alkyd wax, is used as a binder, and a coloring ink containing an appropriate color of an anthraquinone pigment or a dye as a coloring agent.凹 Gravure printing, screen printing, etc. can be used. The thickness of the finish layer 6 is a method of forming a light-transmitting pattern. As a method of forming the finish layer 6, a normal print such as a printing method or a lithography method is preferably 1 to 3 Å #ιπ. The planar shape of the light shielding portion 4 is determined by the light transmitting portion □ surrounded by the light shielding portion 4. 201014502 In detail, the so-called light-transmitting display pattern is a pattern in which the display state is switched or not displayed based on the presence or absence of light irradiation from the back of the operation panel. The above-described light-transmitting display pattern is not limited to a simple geometric pattern such as a triangle or a quadrangle, and for example, a pattern of an operation icon can be formed. The light shielding portion 4 is formed of an insulating black ink. The insulating black ink is used to provide an ink having the following characteristics to the operation panel: the shielding light that does not leak light in the light shielding portion 4 from the back surface illumination, and the malfunction of the electrostatic capacitance switch does not occur in the operation of the operation panel. Or insulation without action. The insulating black ink is composed of at least four kinds of coloring pigments. At least one of the insulating black inks is composed of a carbonaceous powder having a concentration of 30% by weight or less in the nonvolatile content of the entire insulating black ink. When the concentration of the carbonaceous powder is 30% by weight or less, the black ink for printing can be made insulating, and the capacitance switch of the operation panel can be prevented from malfunction or malfunction. The particle diameter of the carbonaceous powder is preferably from 1 to 2 〇〇ηη. In this case, if it is larger than 200 nm, the printing suitability for character reproducibility is deteriorated, and if it is less than 1 nm, the blackness or the shielding property is lowered. It is preferable to use a blue, red or yellow pigment for at least three of the remaining coloring pigments. This is because it can be black by mixing. As the blue pigment, for example, (4) coffee 15 (copper cyanine) or the like can be used, and as the red pigment, for example, brain tRedi49 (permanent red BL), Pig嶋t Red (4) plus qing _ _ plus (1), etc. can be used. As the yellow pigment, for example, Pigment Yeii〇w 12 (double scent yellow) or the like can be used. As a pigment other than a blue type, a red type, and a yellow type, for example, Pigment Black 1 (Phenyl Black), Pigment Black 11 (Iron Black), etc. can be used as a black type pigment. The resin binder used in the insulating black ink is a combination of any of acrylic laurel, urethane I resin, ethylene ethoxide/acetic acid ethyl vinegar copolymer resin, or a combination thereof. When the light shielding portion 4 is formed by gravure printing, sufficient shielding properties can be obtained by laminating two or more layers. Further, the film thickness of the entire ink layer of the light shielding portion 4 is preferably 2 〇 " m or less. In the resin molded article 9, when the transfer layer 8 is transferred by a transfer method or the like, and the operation panel 11 is formed by transfer processing, the ink layer medium in the light shielding portion 4 is used. A difference in height between the thickness and the thickness of the portion other than the light shielding portion 4 is caused, and the appearance is not beautiful. Further, when the operation surface is formed by the attaching method described later, the same height difference as described above can be easily caused. In addition, when the operation panel 11 is formed by the simultaneous transfer method, the thickness of the ink layer is thick, and the ink is melted and melted easily due to the hot pressing of the molding resin 32. The pattern of the 4th road is deformed, that is, the so-called ink flow is likely to occur. In the case of the transfer, it is also possible to use the transfer layer 7 to connect the above-mentioned layer 7 to form the resin layer by the forming layer. When the material of the resin molded article 9 is a polyacrylic resin, the polyacrylic resin can be used as the material of the adhesive layer 7. Further, the material of the resin molded article 9 is used. When it is a polyphenylene ether polystyrene resin, a polycarbonate resin, a styrene copolymer resin, or a polystyrene blend resin, a polyacrylic resin having affinity with these resins and a poly A styrene resin, a polyamide resin, or the like is used as the material of the adhesive layer 7. As a method of forming the adhesive layer 7, a coating method such as a gravure coating method, a roll coating method, or a delayed roll coating method can be used. Cloth or gravure, screen printing, etc. Next, the dry film thickness of the layer 7 is generally 1 to 5 μm. Next, a method of manufacturing the operation panel 11 by the simultaneous molding transfer method will be described with reference to Fig. 2. First, the transfer sheet 1 is fed into a movable type and In the case of the mold 31 for molding which is formed by a fixed type, in this case, the transfer sheet 1 of a single sheet can be fed one by one, and the transfer of the long transfer sheet i can be intermittently transferred. When the pattern portion is fed in, when the long-length transfer sheet 1 is used, a conveying device having a positioning mechanism can be used to make the orientation of the transfer sheet and the molding die 31 into effect. When the sheet is fed intermittently, the mark printed on the transfer sheet can be detected by the sensor, and the amount of the transfer sheet can be controlled to transfer the pattern portion and the cavity. The positioning of the transfer sheet 1 is fixed by a movable type and a fixed type. 11 201014502 The transfer sheet 1 is disposed in a molding die in such a manner that the surface of the base sheet 2 on which the transfer layer 8 is not formed faces the cavity. 31. After the molding die 31 is closed, the molding resin 32 is injected and filled from the gate of the mold. In the molding die 31, 'the same as the resin molded article 9 is formed', the transfer sheet 1 is placed on the molding surface (see Fig. 2). After the resin molded article 9 is cooled and solidified, the molding die 3 is opened. When the base sheet 2 is peeled off, the transfer layer 8 is transferred onto the surface of the resin molded article 9 to complete the transfer step (see Fig. 2(b)).
