PRESSURE-SENSITIVE ADHESIVE TAPE, LAMINATE, AND IMAGE DISPLAY DEVICE

摘要

Provided is a pressure-sensitive adhesive tape which is highly transparent and has excellent adhesive force in application to a polycarbonate plate and an acrylic plate and with which it is possible to inhibit lifting or peeling from occurring at the interface between the polycarbonate plate or acrylic plate and the adhesive layer even under high-temperature conditions. Also provided are a laminate and an image display device both produced using the pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape has a pressure-sensitive adhesive layer comprising a pressure-sensitive adhesive composition containing a copolymer, wherein the copolymer comprises a structural unit derived from a monomer having a bicyclo structure and one olefinic double bond in the molecule and a structural unit derived from a (meth)acrylic ester monomer having a structure represented by general formula (1), the proportion of the structural unit derived from a monomer having a bicyclo structure and one olefinic double bond in the molecule in 100 parts by weight the copolymer being 10-60 parts by weight and the proportion of the structural unit derived from a (meth)acrylic ester monomer having a structure represented by general formula (1) in 100 parts by weight of the copolymer being 30-90 parts by weight. The pressure-sensitive adhesive tape has a total light transmittance in the visible-light wavelength region of 90% or higher and a haze of 1% or lower. In general formula (1), R1 represents a hydrogen atom or methyl, and R2 represents a C3-14 alkyl, in which one or more of the hydrogen atoms may have been replaced with a cycloalkyl.
