Abstract: A laminate of optical elements comprises a transparent first optical element, a second optical element, and a transparent pressure-sensitive adhesive layer for bonding the first optical element to the second optical element. The pressure-sensitive adhesive layer comprises a base adhesive zone, a transparent refractive index-adjusting zone. The base adhesive zone is made essentially of a transparent base pressure-sensitive adhesive material and formed over a given range from a first principal surface of the pressure-sensitive adhesive layer facing the first optical element, in a thickness direction of the pressure-sensitive adhesive layer. The a transparent, adherent, refractive index-adjusting zone is formed over a given range from a second principal surface of the pressure-sensitive adhesive layer facing the second optical element.

Abstract: As one sensor layer structure for a capacitive touch panel, a layer structure in which a transparent electroconductive layer is formed on each of opposite surfaces of a single film substrate, so-called GFD structure, is used. In the structure, for sufficiently suppressing internal reflection from the transparent electroconductive layer, it is necessary to employ a technique of forming one or more refractive index adjustment (IM) layers on each of the opposite surfaces of the single film substrate. This causes a problem that production yield is likely to deteriorate, and a production cost is increased. The present invention is directed to solving such a problem and, specifically, to laminating a refractive index adjustment zone-formed pressure-sensitive adhesive layer capable of being produced easily and at low cost, to each transparent electroconductive layer of a double-sided transparent electroconductive film, so as to effectively suppress internal reflection in the resulting laminate.

Abstract: In the case where a pressure-sensitive adhesive sheet comprising a pressure-sensitive adhesive layer having a refractive index adjustment zone is provided in such a manner that two PET separators are laminated to opposite surfaces of the pressure-sensitive adhesive layer, it is difficult to distinguish between obverse and reverse sides of the pressure-sensitive adhesive sheet itself. The present invention is directed to solving the above problems and, specifically, to offering a pressure-sensitive adhesive sheet having a refractive index adjustment zone capable of being easily produced at low cost, in a state in which it is preliminarily laminated with a substrate provided with an electroconductive layer, thereby making it possible to resolve complexity in handling (to easily distinguish between one surface defined by the refractive index adjustment zone and the other surface defined by the remaining zone).
