Abstract:
The present invention relates to a pressure-sensitive adhesive sheet including: a laminated structure in which a light-shielding layer, a white or silver layer, and a colored layer are laminated in this order; and at least one pressure-sensitive adhesive layer as at least one surface layer, in which at least one surface of the pressure-sensitive adhesive sheet has L* of 30 or more and C* of 3 or more, L* representing a luminosity and C* representing a chromaticness, and in which the pressure-sensitive adhesive sheet as a whole has a transmittance of a light having a wavelength of 550 nm of 0.3% or less. The pressure-sensitive adhesive sheet of the invention is excellent in light-shielding property irrespective of the thinness thereof as well as in decorativity due to the surface thereof that is colored with a bright color.
