Description of the Invention: [Technical Field] The present invention relates to a double-sided adhesive sheet suitable for exposing at least one of a metal to a surface to a member. Further, the present invention relates to a double-sided adhesive sheet having a release sheet formed on both surfaces of such a double-sided adhesive sheet, and an optical laminate using a double-sided adhesive sheet followed by an optical member. [Prior Art] In recent years, personal digital assistants equipped with touch panels on personal digital assistants are rapidly spreading. Generally, the touch panel has two or more transparent conductors laminated on the liquid crystal panel. The transparent conductor includes a base material, a tin-doped indium oxide film (hereinafter referred to as "iT〇 (Oxide)"), a metal terminal, and a metal wiring provided on the surface of the substrate. + A double-sided adhesive sheet containing a layer of an adhesive layer containing one of an acrylic adhesive is sometimes used in connection with a transparent conductor or a contact between a touch panel and a liquid crystal panel (Patent Document υ. In the main component contained in the acid-based adhesive, there is a case where the excipient-based acrylic monomer is monofluorene in order to facilitate crosslinking, but since the carboxyl group is acidic, the metal corrosion property is enhanced. When the double-sided adhesive sheet is in contact with the clear shape of the metal terminal of the transparent conductor, there is a case where the metal terminal and the metal wiring are reduced to reduce the conductivity. As a method of resisting metal corrosion, the patent is patented. Document 2 discloses a method of making an adhesive layer containing an anti-metal etchant. [Prior Art Document] 163763.doc 201247832 [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2010-90344 [Patent Document 2] [Problems to be Solved by the Invention] On the surface of the touch panel and the liquid crystal panel or the surface of the transparent conductor constituting the touch panel, there are terminals, wirings, and frames. In the case where printing or the like is formed, irregularities are formed. In the case where the touch panel and the liquid crystal panel are followed by the transparent conductors, it is expected that the surface opposite to the surface contacting the unevenness can be improved by improving the followability to the unevenness. In order to obtain a double-sided adhesive sheet having a high degree of unevenness and conformability, it is preferable to make the adhesive layer slightly thick. Therefore, if thickening is attempted, it is described in Patent Document 1. The double-sided adhesive sheet and the anti-metal corrosion agent can be used to determine that the use of the metal-resistance agent becomes high and the cost is high, and there is a tendency for the double-sided adhesive sheet to yellow itself during long-term use. Such a yellowing can reduce the display performance of the product. Therefore, it is easy to be a fatal defect. Therefore, the inventors of the present invention have been able to prevent the corrosion of the metal in the metal, and to prevent the corrosion of the metal in the metal. The double-sided adhesive sheet which can prevent yellowing and its application products are repeatedly studied. [Technical means for solving the problem] The present inventors repeatedly conducted intensive research and concluded It has been found that by making the double-sided adhesive sheet contain two or more adhesive layers, and further trying to control the use conditions of the adhesive or metal corrosion inhibitor having several groups, the above problem can be solved by 163763.doc 201247832.

In the case of thickening the adhesive layer, it is sufficient to form an adhesive layer and then overlap the same adhesive layer. A solvent is contained in the coating liquid. As the solvent, for example, methanol, ethanol, isopropanol, acetone, methyl ethyl ketone, toluene, n-hexane, n-butanol, methyl isobutyl hydrazine, methyl butyl ketone, ethyl butyl ketone, or the like can be used. Cyclohexanone, ethyl acetate, butyl acetate, propylene glycol monoterpene ether acetate, ethylene glycol monoethyl ether, propylene glycol monoterpene ether, fluorenyl-fluorenyl-2-pyrrolidone, and the like. These may be used alone or in combination of two or more. The manufacturing method (2) is a manufacturing method having the steps of: forming a coating liquid for forming a first outermost adhesive layer, a coating liquid for forming an intermediate adhesive layer, and forming a second outermost adhesive layer; The coating liquid of the agent layer is simultaneously applied to the first release sheet in multiple layers and heated; and the second release sheet is laminated on the formed second outermost adhesive layer. Examples of the simultaneous multilayer coating method include a die coating method, a slide coating method, a curtain coating method, and the like. Among these, it is not easy to be clogged by drying of the coating liquid, and it is easy to form a relatively thick layer compared with other coating methods, and the like is preferably a die coating method. (Operation and effect) In the double-sided adhesive sheet 10a of the above embodiment, when the metal exposed surface of the first optical member is bonded to the second outermost adhesive layer u, the first outermost adhesive is applied. The contact surface of the second optical member of the layer of tantalum is formed with a corroded component contained in the interior of the sheet 10a due to the fact that the film becomes a barrier film of the metal film and the metal film is resistant to the metal film (4). I63763.doc • 25-201247832 The carboxyl group-containing monomer from the second outermost adhesive layer 13 or the acid component transferred from the aggregate containing the same is not easily contacted with the metal. Therefore, it is possible to prevent the corrosion of the metal of the first optical member in the first outermost adhesive layer, and further, since the outermost adhesive layer of the first layer does not have a carboxyl group, the corrosion resistance becomes higher. . In addition, the adhesive layer is set to three layers, and only the i-th outermost adhesive layer U contains a metal corrosion inhibitor at a sufficient concentration, so that the use of the metal corrosion inhibitor can be reduced. Further, since the double-sided adhesive sheet 1Ga can be easily thickened by the adhesive, the first outermost adhesive layer U contains the antioxidant, so that the conductivity of the ITO film can be lowered. Further, in the double-sided adhesive sheet 10a, the i-th outermost adhesive layer u and the outermost adhesive layer 13 contain different kinds of adhesives. That is, an acrylic adhesive containing a single (4) acid-based monomer is contained in the outermost adhesive layer η, and an acrylic monomer containing a carboxyl group is used in the second outermost adhesive layer 13. Acrylic adhesive. In addition, the first member and the second optical member contain completely different materials and are difficult to use. The adhesive is then used, but by the first! The type of the adhesive of the outermost adhesive layer U and the second outermost adhesive layer 13 is different, and the i-th optical member and the second optical member which are completely different materials can be easily followed. The second outermost adhesive layer 13 using an enoenic acid-based adhesive containing a carboxyl group-containing acrylic monomer unit can improve the adhesion to the first light. For example, if the second outermost adhesive layer 13 is used, the polarizing plate of the liquid crystal panel which is subjected to the surface treatment and has a lower adhesion property can be further adhered to with higher adhesion by the second outer layer 163763.doc • 26 - 201247832. In particular, when a second optical member including a resin having no polar group such as a polyolefin resin (for example, a polypropylene resin or a cycloolefin resin) is used, the adhesion can be improved. Therefore, when the second optical member is in the form of a front panel including an acrylic resin sheet or a polycarbonate sheet, the adhesion can be improved to prevent bulging. (Second Embodiment) &lt;Double-sided adhesive sheet&gt; A second embodiment of the double-sided adhesive sheet of the present invention will be described.
