A double-sided pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is substantially free of bubbles and includes an acrylic polymer (A) and hollow microspheres. The acrylic polymer (A) includes a monomer composition containing (meth)acrylic acid alkyl ester (a1) and a polar group-containing copolymerizable monomer (a2) with polymerizable unsaturated double bond. The (meth)acrylic acid alkyl ester (a1) includes a linear-chain alkyl group with a carbon number of 1 to 20 and a branched-chain alkyl group with a carbon number of 1 to 20. The monomer composition contains the polar group-containing copolymerizable monomer (a2) in an amount of 5 to 9 parts by mass, based on 100 parts by mass of a total of the (meth)acrylic acid alkyl ester (a1) and the polar group-containing copolymerizable monomer (a2).
Abstract:

Abstract:
The present subject matter provides a shrink film free of silicon-containing material, fluorine-containing material, and solvent-formed seams. The shrink film utilizes a water soluble layer covering an adhesive layer. The water soluble layer is in dry form and non-tacky, allowing processing of the shrink film subsequent to adhesive application to the shrink film. When the water soluble layer is dissolved, the adhesive layer is exposed and is capable of forming a permanent bond. The adhesive can be used to form a seam in the film and/or can be used to form a bond between the film and a substrate. The water soluble layer facilitates removal of an optional release liner from the adhesive. A substrate with the shrink film attached thereto and a related method of attaching a heat shrinkable film to a substrate are also disclosed.
