  • Patent number: 8722185
    Abstract: The present invention provides a pressure-sensitive adhesive sheet large in adhesive force when used for a surface of a glass member and capable of reducing the adhesive force to a degree allowing the occurrence of the cracking or breakage of the glass member to be suppressed when the sheet is peeled from the surface of the glass member. The pressure-sensitive adhesive sheet for glass plates of the present invention includes a pressure-sensitive adhesive layer including an acrylic polymer, wherein the content of the acrylic polymer in the pressure-sensitive adhesive layer is 30% by weight or more in relation to the total amount (100% by weight) of the pressure-sensitive adhesive layer; the acrylic polymer substantially includes no acidic functional group; the solvent-insoluble fraction of the pressure-sensitive adhesive layer is 50% or more; and the adhesive force to glass as determined by a specific method is 12.0 N or less.
