[0513] Using each of the transparent film substrates produced above as a support, the surface of the photosensitive layer 1 exposed by peeling off the protective film of the transfer film selected from the transfer films A-1 to A-5 was bonded and laminated on the On the transparent film substrate, the laminated body A which has the layer structure of a temporary support body / photosensitive layer 1 / transparent film substrate was formed. The lamination conditions at this time were a lamination roll temperature of 110° C., a linear pressure of 3 N / cm, and a transport speed of 2 m / min.
[0514] Next, the surface of the photosensitive layer 2 exposed by peeling off the protective film of the transfer film selected from among the transfer films B-1 to B-8 is bonded and laminated on the surface of the photosensitive layer 2 exposed by peeling the temporary support from the laminate A. On the surface of the...

[0528] The crosslink density was calculated by the following method.
[0529] (A) Calculation of crosslink density in the first surface layer part
[0530] First, the temporary support was peeled off from the laminate, and a cellophane tape #600 (manufactured by 3M Japan Limited) was attached to the surface of the resin layer 2 exposed by peeling the temporary support, and the resin layer 2 and the resin layer 2 were peeled from the transparent film substrate through the cellophane tape. Resin layer 1. Using a fully automatic microscopic FT-IR system LUMOS (manufactured by Bruke...

Abstract
Provided are a stacked body having excellent adhesion between an oxide particle-containing layer and a resin layer over a base material, a stacked body manufacturing method, and a capacitive input device. The stacked body comprises: a base material; an oxide particle-containing layer including at least one type of metal oxide particles selected from the group consisting of titanium oxide particles and zirconium oxide particles; and a resin layer which is a cured product of a photosensitive composition disposed on a surface of the oxide particle-containing layer, and which has an internal stress of less than or equal to 1.0 MPa, wherein a crosslinking density of an ethylenic unsaturated group in a first upper-layer portion including a surface in contact with the oxide particle-containing layer is equal to or more than 1.2 mmol / g. The stacked body manufacturing method comprises a step of forming a photosensitive layer and a step of forming a resin layer.
Description
technical field [0001] The present invention relates to a laminated body, a method for manufacturing the laminated body, and a capacitive input device. Background technique [0002] In electronic equipment such as mobile phones, car navigation systems, personal computers, ticket vending machines, and bank terminals, tablet-type input devices have been arranged on the surface of liquid crystal devices and the like in recent years. There is a device for inputting information corresponding to a pointing image by touching a portion where the pointing image is displayed with a finger or a stylus while referring to a pointing image displayed on an image display area of a liquid crystal device. [0003] The input device (hereinafter, also referred to as a touch panel) includes a resistive film type, a capacitive type, and the like. [0004] The capacitive input device has an advantage that it is only necessary to form a light-transmitting conductive film on one substrate. Among...
