Abstract: A pressure-sensitive adhesive sheet including a plastic substrate having a thickness of more than 0 μm and less than 2.0 μm and a pressure-sensitive adhesive layer on at least one side of the plastic substrate. The pressure-sensitive adhesive layer contains an acrylic polymer or a rubber-based polymer in an amount of 50 wt % or more relative to a total amount of the pressure-sensitive adhesive layer. The acrylic polymer is formed of a monomer mixture containing the specific alkyl (meth)acrylate monomer in an amount of 50.0 to 99.8 wt % relative to a total amount of monomer components and a polar group-containing monomer in an amount of 0.01 to 20 wt % relative to the total amount of monomer components.

Abstract: The present invention relates to an adhesive sheet which is to be applied to an adherend, in which the adhesive sheet includes an adhesive layer containing a volume change substance that expands in volume upon reception of an external stimulus and thereafter contracts in volume with a lapse of time, and the adhesive sheet is configured so that a plurality of surface irregularities are formed on at least one surface of the adhesive layer as a result of the volume expansion of the volume change substance and that channel areas for air bubble expelling are capable of being formed between said one surface of the adhesive layer and the adherend based on the surface irregularities.

Abstract: Provided is a pressure-sensitive adhesive (PSA) product having specifications in which the level of volatile organic compound emissions has been minimized, and effectively displaying those specifications. The PSA product includes a PSA layer having an adhesive face capable of attaching to an adherend, and a backing sheet disposed on a back face of the PSA layer. The PSA layer produces toluene emissions of at most 20 μg/g and produces total volatile organic compound emissions of at most 300 μg/g. The backing sheet has a mark in a color selected from green and blue displayed on a back face thereof.
