Abstract: A laminated body includes: an antireflection film; and a protection film bonded onto the antireflection film. The adhesive layer is a layer with a material formed by cross-linking, with a cross-linking agent (B), and a (meth)acrylic acid ester copolymer. The (meth)acrylic acid ester copolymer (A) is a copolymer formed by polymerizing monomer components including, in relation to the total amount of the monomer components set at 100% by mass, 70 to 98% by mass of a (meth)acrylic acid alkyl ester monomer (a) including a noncyclic alkyl group containing 4 to 9 carbon atoms, 1.5 to 25% by mass of a (meth)acrylic acid ester monomer (b) containing an aliphatic ring, and 0.5 to 5% by mass of a (meth)acrylic-based monomer (c) containing a functional group exhibiting reactivity with the cross-linking agent (B). The area proportion of the components each having a molecular weight of 100,000 or less, is less than 3.0%.

Abstract: A pressure sensitive adhesive sheet for use for a battery is provided. The pressure sensitive adhesive sheet comprises a base material, a hard coat layer provided at one side of the base material, and a pressure sensitive adhesive layer provided at a side of the hard coat layer opposite to the base material. The pressure sensitive adhesive sheet can well maintain the adhesive strength to suppress delamination from an adherend even in case of contact with an electrolyte solution.

Abstract: An optical-diffusion film for display which, particularly when applied to a display device using a collimated backlight as a backlight for the display panel, can efficiently diffuse and emit a highly directional light emitted from the collimated backlight toward the front of the display device as image display light, without allowing straight transmission of the highly directional light, and a display device using the optical-diffusion film for display are provided.Disclosed is a single layered optical-diffusion film having a columnar structure in which plural pillar-shaped objects having a relatively high refractive index are arranged to stand close together in a film thickness direction in a region having a relatively low refractive index, in which the film thickness of the optical-diffusion film has a value within the range of 60 to 700 μm, and the haze value obtainable in the case in which light is made incident in the normal line direction of the film plane has a value of 80% or more.
