PROBLEM TO BE SOLVED: To provide an adhesive sheet which is excellent in antistatic properties, temporal stability of surface resistivity, whitening resistance, pickup properties and removability, and can also suppress whitening (whitening caused by moisture absorption) during storage in a humid condition.SOLUTION: An adhesive sheet has an antistatic layer provided on a first surface of a base material and an adhesive layer on a second surface of the base material. The antistatic layer is formed of an antistatic agent composition which contains a polyaniline sulfonic acid as a conductive polymer component, a polyester resin as a binder, and an isocyanate crosslinking agent as a crosslinking agent. The adhesive layer is formed of a water dispersion type acrylic adhesive composition containing an acryl emulsion-based polymer which contains at least (meth)acrylic acid alkyl ester (A) of 70-99.5 mass% and a carboxyl group-containing unsaturated monomer (B) of 0.5-10 mass%, as monomer components, and is polymerized using a reactive emulsifier containing a radical-polymerizable functional group in the molecule.SELECTED DRAWING: None |
