Abstract: A pressure sensitive adhesive sheet for batteries that includes a base material and a pressure sensitive adhesive layer provided on one surface side of the base material and containing inorganic fine particles. When D50 and D90 are defined as a volume-based accumulated 50% particle diameter of the inorganic fine particles and a volume-based accumulated 90% particle diameter of the inorganic fine particles, respectively, in a particle size distribution of the inorganic fine particles in the pressure sensitive adhesive layer, the D50 is 0.5 μm or more and 2.8 μm or less, and the ratio of the D90 to the D50 (D90/D50) is 1.3 or more and 2.0 or less. The particle size distribution is measured by image analysis on a surface of the pressure sensitive adhesive layer opposite to the base material.

Abstract: A pressure sensitive adhesive composition containing: a (meth)acrylic ester polymer including butyl methacrylate and a reactive functional group-containing monomer as monomer units that constitute the polymer; and an inorganic filler, a pressure sensitive adhesive obtained by crosslinking the pressure sensitive adhesive composition, and a pressure sensitive adhesive sheet comprising at least a pressure sensitive adhesive layer that is formed from the above pressure sensitive adhesive composition. The above pressure sensitive adhesive composition allows the inorganic filler to be uniformly dispersed in a short time even when a dispersant is not contained. Moreover, in the above pressure sensitive adhesive and the pressure sensitive adhesive layer of the pressure sensitive adhesive sheet, the inorganic filler is uniformly dispersed.

Abstract: A pressure sensitive adhesive sheet is provided which comprises a base material having insulation properties, an inorganic filler-containing resin layer provided at least at one side of the base material and containing an insulating inorganic filler, and a pressure sensitive adhesive layer provided as an outermost layer of at least one surface. According to such a pressure sensitive adhesive sheet, insulation properties can be ensured even when the base material undergoes carbonization and/or combustion/decomposition due to high temperatures and insulation breakdown occurs in the base material.

Abstract: A pressure sensitive adhesive sheet for use for a battery is provided. The pressure sensitive adhesive sheet comprises a base material, a hard coat layer provided at one side of the base material, and a pressure sensitive adhesive layer provided at a side of the hard coat layer opposite to the base material. The pressure sensitive adhesive sheet can well maintain the adhesive strength to suppress delamination from an adherend even in case of contact with an electrolyte solution.
