PRESSURE-SENSITIVE ADHESIVE SHEET, OPTICAL MEMBER, AND TOUCH PANEL
An object of the present invention is to provide a pressure-sensitive adhesive sheet enables a pressure-sensitive adhesive layer to be formed, wherein the pressure-sensitive adhesive layer has a low dielectric constant, is excellent in level difference conformability while maintaining adhesive strength and adhesion reliability at high temperatures, and suitable for laminating a metal mesh film and the like. The pressure-sensitive adhesive sheet of the present invention is a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer, the pressure-sensitive adhesive layer containing an acrylic polymer (A) and a hydrogenated polyolefinic resin (B) that exhibits liquid flowability at 25° C. The pressure-sensitive adhesive layer has a dielectric constant at a frequency of 1 MHz of from 2.3 to 3.5. The pressure-sensitive adhesive sheet has a 180° peel adhesive strength to a glass plate at a tensile speed of 300 mm/minute at 65° C. of 6 N/20 mm or more. In the pressure-sensitive adhesive sheet, the proportion of the 180° peel adhesive strength to a glass plate at a tensile speed of 300 mm/minute at 65° C. to the 180° peel adhesive strength to a glass plate at a tensile speed of 300 mm/minute at 25° C. (180° peel adhesive strength to a glass plate at a tensile speed of 300 mm/minute at 65° C./180° peel adhesive strength to a glass plate at a tensile speed of 300 mm/minute at 25° C.×100) is 30 or more.
ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, AND MONOLAYER FILM AND MULTILAYER STRUCTURE CONTAINING THE SAME
The present invention relates to an ethylene-vinyl alcohol copolymer composition, a single-layer film and a multilayer structure containing the same. Said ethylene-vinyl alcohol copolymer composition includes an ethylene-vinyl alcohol copolymer, an antioxidant, and a fluorine-containing compound; and the ratio of the antioxidant content to the fluorine content is 0.5 to 65. Thereby, the film containing said ethylene-vinyl alcohol copolymer composition not only has good heat resistance, but also can avoid the situation that a large number of gels are generated during the preparation process.
