Description of the Invention: [Technical Field] The present invention relates to a laminated extruded resin sheet and a surface coated sheet used in a touch panel. [Prior Art] For example, in a navigation system, a portable information terminal, an operation panel of an industrial machine, a screen of a personal computer, a portable game machine, or the like, a touch panel with a transparent electrode is used. As the board used for the touch panel, in addition to the thin glass, a resin plate can be cited. In the touch panel, for example, an operator or a stylus pen is directly contacted by a finger, and transparency, impact resistance, light weight, and surface non-damage are emphasized. For such a request, since a thin glass is resistant to punching and lightness, a resin plate has recently been used. Patent Document 1 discloses a polycarbonate resin laminate in which a thermoplastic polyurethane resin layer having a hardness of 85 to 95 is laminated on at least one surface of a polycarbonate resin sheet. . Further, Patent Document 2 discloses that an active ray hardened layer (A) having a pencil hardness of 3 Å or more and a pencil having a thickness of 1 to 20 μm is laminated on the polymer resin substrate in this order with a thickness of 50 to 300 μm. A polymer resin laminate having a hardness of 4H or more of a hard coat layer (Β). However, the resin plate described in Patent Document 1 compensates for the easy damage of the polycarbonate resin sheet by the polyurethane resin layer laminated on the polycarbonate resin sheet. However, the polyurethane resin is affected by the polycarbonate resin sheet of the substrate due to the low rigidity of -5-201041737. When the characters are written by a stylus or the like, the surface is deformed. Further, in the resin plate described in Patent Document 2, the hardness of the hard coat layer (B) can be improved by laminating the hard coat layer (B) on the active optically-curable layer (A). However, since the active light hardening layer (A) and the hard coat layer (B) must be laminated separately on the substrate, there is a problem in productivity. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. The subject is to provide a laminated resin sheet for a touch panel and a surface coating sheet for a touch panel which are not easily damaged on the surface and which are relatively easy to manufacture. Means for Solving the Problems In order to solve the above problems, the inventors of the present invention have repeatedly focused their efforts on the above-mentioned problems, and have found that the present invention has finally been completed by the following means. (1) A laminated and extruded resin sheet for a touch panel which is laminated on a surface of a touch side of a polycarbonate resin layer and laminated by a co-extrusion molding to form a propylene-6 - 201041737 olefin resin layer to make. (2) The laminated resin sheet for a touch panel according to the above (1), wherein the polycarbonate resin layer has a thickness of 50% or more of the entire thickness. (3) The laminated and extruded resin sheet for a touch panel according to the above (1) or (2), which is formed by laminating an acrylic resin layer on both surfaces of the polycarbonate resin layer. The laminated resin sheet for a touch panel according to any one of the above aspects, wherein the acrylic resin layer is made of a methacrylic resin and a rubbery polymer. (5) A surface-coated board for a touch panel which is formed by coating a cured film on a surface of a touch-side of a laminated and extruded resin sheet according to any one of the above (1) to (4). (6) The surface-coated board for a touch panel according to the above (5), wherein the cured film has a scratch-resistant hardened film.效果 Effect of the Invention The laminated and extruded resin sheet of the present invention is suitable for use in a touch panel because the surface is not easily damaged. Further, the surface-coated sheet formed by coating the cured film on the surface on the contact side of the laminated resin sheet can be suitably used for the touch of a stylus having a sharp tip. Further, the laminated extruded resin sheet of the present invention is obtained by co-extrusion molding, and since it is not necessary to laminate the active light hardening layer and the hard coat layer on the substrate as in the related art, it is relatively easy to manufacture. . [Embodiment] The embodiment of the present invention is a laminate extrusion resin sheet (hereinafter also referred to as an extrusion resin sheet) which is formed on the surface of at least the touch side of the polycarbonate resin layer by co-extrusion. It is formed by laminating an acrylic resin layer and used for a touch panel. The polycarbonate resin constituting the polycarbonate resin layer is a polymer composed of a carbonate group (-0-(c = o) - 0-) in which the bonding sites of the monomer units are each. The polycarbonate resin is, for example, a resin obtained by reacting one or more kinds of divalent phenols with one or more kinds of carbonylating agents by an interfacial polycondensation method, a melt transesterification method, or the like, by a solid phase ester.

Not easy to break. In particular, it is preferred that the acrylic resin layer be a layer composed of a methacrylic resin and a rubbery polymer by mixing a rubbery polymer in a methacrylic resin. The rubbery polymer is, for example, an acrylic multilayer structure polymer, or graft polymerized in a rubber polymer of 5 -10-201041737 to 80 parts by weight in an amount of 20 to 95 parts by weight of a propylene acid unsaturated.

In the graft copolymer obtained by graft-polymerizing 20 to 95 parts by weight of an ethylenically unsaturated monomer to the above-mentioned 5 to 80 parts by weight of the rubbery polymer, 'as the rubbery polymer, for example, polybutylene can be used.

Further, examples of the ethylene monomer for graft copolymerization in the rubbery polymer include styrene, acrylonitrile, and alkyl (meth)acrylate. Such a graft copolymer is described in, for example, JP-A-59-147A, and JP-A-47-9740. When the rubbery polymer is dispersed in the acrylic resin, the rubbery polymer is usually dispersed in an amount of from 3 to 150 parts by weight, preferably from 5 to 50 parts by weight, based on 1 part by weight of the acrylic resin. If the amount of the rubbery polymer is too large, the surface hardness is lowered. Further, if the amount of the rubbery polymer is too small, it is difficult to obtain an effect that the laminated resin sheet is less likely to be broken. Further, for example, a light diffusing agent may be added to each of the polycarbonate resin layer and the acrylic resin layer. One or more additives such as a matting agent, a dye, a light stabilizer, a UV absorber, an antioxidant, a mold release agent, a flame retardant, and an antistatic agent. The laminated extruded resin sheet of the present invention is produced by laminating and integrating a polycarbonate resin layer and an acrylic resin layer by co-extrusion molding. The co-extrusion molding system can melt-knead the material of the polycarbonate resin layer of the first -12-201041737 and the material of the acrylic resin layer by using two or three one-axis or two-axis extruders. It is carried out by laminating by a feedblock die or a multi-manifold die or the like. The resin sheet is extruded and laminated by laminating and laminating, and the laminate can be cooled and solidified by, for example, a roll unit or the like to obtain a laminated extruded resin sheet of the present invention. Hereinafter, an embodiment of a method for producing a laminated extruded resin sheet of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic explanatory view showing a method of manufacturing the laminated extruded resin sheet of the embodiment. Fig. 2 is a schematic cross-sectional view showing the metal roll and the elastic roll of the embodiment. As shown in Fig. 1, first, each of the polycarbonate resin and the acrylic resin is heated by the individual extruders 1, 2, and melt-kneaded, while being pressed out by the die 3 for co-extrusion molding. Integration. Then, the sheet-like molten laminate which is uniformly pressed by the die 3 is pressed out of the resin sheet 4, and is sandwiched between the two cooling rolls 5Q which are disposed in the horizontal direction in the horizontal direction, thereby obtaining the lamination pressure for the touch panel. The resin plate 11 is taken out. As shown in Fig. 2, the cooling roll 5 is composed of a highly rigid metal roll 6 and an elastic roll 7 having a metal film 9 at its outer peripheral portion, i.e., a metal elastic roll 7. At least one of the metal roller 6 and the metal elastic roller 7 is connected to a rotation driving means such as a motor, and the two rollers are rotated at a predetermined peripheral speed. The high-rigidity metal roll 6 is a sheet-like lamination in which the metal roll 6 and the metal elastic roll 7 are supported, and the winding roll in which the resin sheet 11 is wound is extruded. The metal roller 6 is not particularly limited, and a general metal roller which has been conventionally used for extrusion molding can be used. Specific examples include a drill-type roll or a spiral roll, etc. -13-201041737. The surface state of the metal roll 6 may be, for example, a mirror surface, or may have a pattern or a concavity or the like. The metal elastic roller 7 includes a shaft roller 8 that is rotatably provided in a substantially cylindrical shape, and a cylindrical metal film 9 that is placed in contact with the molten laminated resin sheet 4 so as to cover the outer peripheral surface of the shaft roller 8. The fluid 10 is sealed between the isometric roller 8 and the metal film 9, whereby the metal elastic roller 7 exhibits elasticity. The shaft roller 8 is not particularly limited, and is made of, for example, stainless steel. The metal film 9 is made of, for example, stainless steel or the like, and has a thickness of preferably about 2 to 5 mm. The metal film 9 is more preferably a flexible structure having flexibility or flexibility, and preferably has no welded portion. The metal elastic roller 7 having the metal film 9 is excellent in durability, and when the metal film 9 is mirror-finished, the pattern or the unevenness can be imparted to the metal film 9 in the same manner as a normal mirror roll. Since it becomes a roll which can transfer shape, it is easy to use. The metal film 9 is fixed to both end portions of the shaft roller 8, and a fluid 1 封 is sealed between the shaft roller 8 and the metal film 9. Examples of the fluid 1 水 include water, oil, and the like. The temperature of the metal elastic light 7 can be controlled by controlling the temperature of the fluid 1 。. In the aforementioned temperature control, for example, a well-known control method such as PID control or ON-OFF control can be employed. Further, a gas such as air may be used instead of the fluid. When the resin sheet 4 is melt-laminated and supported between the metal light 6 and the metal elastic roller 7, the metal elastic roller 7 presses the resin sheet 4 via the melt lamination, and is recessed along the outer peripheral surface of the metal roll 6. The elastic deformation is performed, and the metal-14-201041737 elastic roller 7 and the metal roller 6 are pressed out of the resin sheet 4 by melt lamination, and are brought into contact at a predetermined contact length L. The contact length L may be 1 to 20 mm, preferably 1 to 10 mm, more preferably 1 to 7 mm. In order to make the contact length L a predetermined flaw, for example, the thickness of the metal thin film 9 and the amount of the fluid 10 to be sealed can be arbitrarily adjusted. Further, the contact length L means that the resin sheet 4 is pressed out by fusion lamination, and the length of the line connecting the metal elastic roller 7 and the metal roller 6 to the point where the contact is started and the point at which the contact ends is reached. When the metal elastic roller 7 and the metal roller 6 are brought into contact with the resin sheet 4 via the melt lamination by the contact length L, the metal roller 6 and the metal elastic roller 7 are brought into contact with each other by the molten laminate extrusion resin sheet 4. In the molten layer which is supported by the rolls, the resin sheet 4 is pressed and uniformly pressed into a planar shape to form a film. When the film formation is carried out in this manner, it is possible to prevent the strain from remaining in the laminated and extruded resin sheet U, and the heat shrinkage characteristics and the hysteresis of the laminated laminated resin sheet 1 tend to be small. Therefore, the laminated resin sheet 11 is laminated and has an effect of suppressing deformation of the touch panel in use in a place where the temperature environment is severe. Specifically, the shrinkage ratio S 1 ( % ) and the shrinkage in the width direction of the lamination-extrusion resin sheet 1 in the laminated resin sheet 11 when the laminate is pressed out of the resin sheet 11 in a thermal environment of 160 ° C for 30 minutes The rate S 2 (%) has a tendency to become 0 to 5 %. When the shrinkage ratios SI and S2 are negative, that is, when the laminate is not pressed to 〇%, if the laminate is pressed out of the resin sheet to be heated, expansion is performed, and when the cured resin film is coated on the laminated resin sheet, the turtle is introduced into the cured film. Cracked and there is a rupture. Further, when the shrinkage ratios s 1 and S 2 exceed 5%, the yield of the product obtained by heating and laminating the resin sheet from -15 to 201041737 and shrinking to increase is lowered. The method of calculating the shrinkage ratios Si and S 2 will be described later. Further, the laminated resin sheet 11 tends to have a hysteresis of 2 〇〇 nm or less. When the touch panel is mounted on the liquid crystal panel, if the hysteresis of the laminated resin sheet 11 constituting the touch panel is 200 nm or less, even if the polarized glasses are worn, the coloring of the touch panel does not occur. . The hysteresis described above is measured by a micro area double refractometer as described later. In order to reduce the heat shrinkage characteristics and hysteresis of the laminated resin sheet 1 1, when the metal sheet 6 and the metal elastic roller 7 are sandwiched by the melt lamination and extrusion of the resin sheet 4, it is preferably formed. The resin sheet 4 is pressed and laminated in the two rolls before the cooling and solidification or during the cooling and solidification. Specifically, the surface temperature (Tr) of the metal roll 6 and the metal elastic roll 7 is preferably (Th-2(TC) STrS (Th + 20t) with respect to the heat distortion temperature (Th) of the polycarbonate resin or the acrylic resin. ), preferably (Th-15.)

^Tr ^ ( Th+10°C ),更佳爲(Th-10°C ) ( Th + 5°C )的範圍。 另一方面,若表面溫度爲(Tr)比(Th-2 0 °C )還低 的溫度,則收縮率S2有變小的傾向。又,若表面溫度(^Tr ^ ( Th + 10 ° C ), more preferably (Th - 10 ° C ) (Th + 5 ° C ). On the other hand, when the surface temperature is a temperature lower than (Tr) ratio (Th-2 0 °C), the shrinkage ratio S2 tends to be small. Also, if the surface temperature (

Further, the peeling marks from the rolls remain on the laminated extruded resin sheet 1 1 and tend to impair the appearance. The surface temperature (Tr) is based on a resin having a high heat distortion temperature (Th) in the polycarbonate resin and the acrylic resin. The heat distortion temperature (Th) system -16-201041737 is not particularly limited and is usually about 60 to 200 °C. The heat distortion temperature (Th) is a temperature determined in accordance with ASTM D-648.

As shown in Fig. 3, the metal elastic roller 15 of the present embodiment is coated with a cylindrical metal film 17 to cover a metal elastic roller on the outer circumferential surface of the shaft roller 16 which is provided in a substantially cylindrical shape. The shaft roller 16 is, for example, a rubber roller made of rubber such as rubber, whereby the metal elastic roller 15 can exhibit elasticity.

Thereby, laminating and extruding the resin sheet becomes more difficult to break. Further, the thickness of the polycarbonate resin layer is usually 95% or less, preferably 90% or less, based on the entire thickness. When the surface hardness of the acrylic resin layer is emphasized, the thickness thereof is preferably ΙΟμηι or more, more preferably 20 to 200 μm. Further, in the three-layer configuration, the thickness of the two acrylic resin layers may be the same or different from each other. The thickness of the laminated resin sheet can be adjusted by the thickness of the resin sheet 4 and the interval between the two cooling rolls 5 by melt lamination from the die 3 described above. When the person operating the touch panel touches the touch panel with a finger, the laminated acrylic resin layer of the present invention is suitable as a touch surface.
