Problems solved by technology

[0007] However, a transparent conductive laminate using a sufficiently thick plastic plate as a transparent base material has sufficient toughness, but lacks a pressing feeling (feel to touch) because of too much toughness. There will be cracking problems during mold removal
[0008] In this case, in order to avoid the above-mentioned problems in die-cutting, it is conceivable to form a transparent conductive layer on a transparent plastic plate formed in advance to a predetermined size, but in this case, there is a problem that operability deteriorates

no. 1 approach

[0068] The functional laminate of the first embodiment has a functional layer in at least one of the plastic film and the plastic film. its specific example Figure 1 to Figure 4 shown. figure 1 and figure 2 Indicates that the plastic film is 2 pieces, image 3 and Figure 4 Indicates the case where there are three plastic films. The position of the functional layer 13 in the laminated body 1 is also different according to the purpose of the functional layer and the method of formation, and can be as follows: figure 1 , image 3 Between the plastic film 11 and the adhesive layer 12 as shown, it is also possible to figure 2 , Figure 4 between the adhesive layers 12 that way. In the functional laminated board of the present embodiment, since the functional layer is present inside the laminate, damage to the functional layer can be prevented and durability can be improved.

no. 2 approach

[0089] The functional laminated board of the second embodiment has a functional layer on at least one surface of the outermost plastic film. its example Figure 5 ~ Figure 7 shown. Figure 5 and Figure 6 It shows the case where the functional layer 13 is provided on the outermost surface of one side of the functional laminated board 1, Figure 7 The case where the functional layer 13 is provided on both outermost surfaces of the functional laminated board 1 is shown. Additionally, it can be done as Figure 6 As shown, in addition to the functional layer 13 provided on the outermost surface, a functional layer 13 is also provided inside the laminate. in addition, Figure 5 ~ Figure 7 Represents a laminate composed of two plastic films 11, which may also be as shown in the first embodiment image 3 , Figure 4 In that way, the laminate is composed of three or more plastic films. Furthermore, the functional layer can also be bonded to the uppermost plastic film by means ...

no. 3 approach

[0117] A third embodiment is a transparent conductive laminate for a touch panel, in which a transparent conductive layer is provided on at least one surface of the transparent laminate. its specific example Figure 8 ~ Figure 10 shown.

Abstract

Disclosed is a functional laminated sheet having flexibility, high body and good die cutting workability. The functional laminated sheet comprises a laminated sheet composed of at least two plastic films bound to each other through an adhesive layer and a functional layer formed on one surface or both surfaces of at least one of the plastic films, wherein the adhesive layer has a Martens hardness of 260 N / mm2 or less. The functional layer is, for example, a layer having an electromagnetic wave shielding function, a heat ray reflection function, a gas barrier function or a planar heat generation function, and can be arranged in the inside of the laminated sheet. Alternatively, the functional layer is a layer having a light reflection function, a light permeation control function or an antifogging function, and can be arranged on the outermost surface of the laminated sheet. Also disclosed is a transparent electrically conductive laminated sheet for a touch panel, which comprises a transparent laminated sheet having a transparent plastic film bonded thereto through the adhesive layer and a transparent electrically conductive layer formed on the transparent laminated sheet.

Description

technical field [0001] The present invention relates to a functional laminated board, which can reduce the thickness while having high toughness, and can prevent the peeling of the plastic film from the adhesive layer during the die-cutting process. In addition, the present invention relates to a transparent conductive laminate for a touch panel that is lightweight, has no risk of breakage, and is excellent in suitability for processing (die processing), and a touch panel using the same. Background technique [0002] In recent years, various functional films such as electromagnetic wave shielding films, heat ray reflective films, gas barrier films, light reflective films, light transmission adjustment films, and anti-fog films have been released. Since these functional films have poor toughness when used alone, they are used by being bonded to reinforcing boards such as plastic boards. [0003] However, a functional laminate made by bonding a functional film to a plastic pl...
