Abstract: The present invention provides a method of stripping multiple plies of a pressure-sensitive adhesive layer, capable of easily separating and dismantling the joint portion in a short time, without affecting the adherend involved. The stripping method of the present invention strips the multiple plies of a pressure-sensitive adhesive layer, including a pressure-sensitive adhesive body having at least a pressure-sensitive adhesive layer containing heat-expandable fine particles and an adherend, the pressure-sensitive adhesive body and the adherend being laminated on each other, and the multiple plies of a pressure-sensitive adhesive layer contain a coloring matter component, and the pressure-sensitive adhesive body and the adherend are stripped from each other, by irradiating the coloring matter with a laser light beam having a wavelength coinciding with the absorption wavelength of the coloring matter and by expanding the heat-expandable fine particles with the aid of the heat thus generated.

Abstract: An optical stack includes: a first optical sheet having a first principal face with a concavo-convex structure and a second principal face at an opposite side from the first principal face; and an adhesive layer that is disposed on the first principal face of the first optical sheet. The concavo-convex structure includes a plurality of dents and flat portions between adjacent ones of the plurality of dents. The adhesive layer is in contact with the flat portions. A surface of the adhesive layer and the first principal face of the first optical sheet together define an internal space within each of the plurality of dents. In a plan view from a normal direction of the first principal face of the first optical sheet, an area ratio of air voids existing at interfaces between the flat portions and the adhesive layer to an area of the first optical sheet is 3% or less.

Abstract: A polymer resin film of the present disclosure has a plurality of through holes extending through the thickness of the polymer resin film. The through holes penetrate a substrate structure of the resin film. The through holes have openings formed in both a first principal surface and a second principal surface of the film. The through holes have a shape in which the area of a cross-section perpendicular to a direction in which the through holes extend is constant from the first principal surface of the film to the second principal surface of the film or increases from the first principal surface toward the second principal surface. The openings in the first principal surface have a diameter of 3 μm or more and 80 μm or less. A variation in a porosity defined by the openings in the first principal surface is 10% or less.
