Abstract: The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.

Abstract: In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, and has the interval between adjacent fine protrusions being no more than the shortest wavelength in the wavelength band for antireflection. At least some of the fine protrusions are fine protrusions having a plurality of apexes.

Abstract: An optical film having high anti-glare properties and favorable fingerprints wiping off properties is provided. The optical film has a first surface, and a second surface which is a surface opposite to the first surface, wherein the optical film comprises an anti-reflection layer and an anti-glare layer in this order from the first surface to the second surface, the first surface has a profile of depressions and projections, the first surface has an arithmetic mean height Sa of 0.05 μm or more specified in ISO 25178-2:2012, and the first surface satisfies the relation represented by the following Expression 1: Sw×Vmp≤2.00 (Expression 1) wherein “Sw” represents a tilt angle (degrees) of 30 μl pure water droplet flowing down on the first surface; and “Vmp” represents a value of a peak material volume (ml/m2) of the first surface specified in ISO 25178-2:2012.
