Abstract: To provide a PSA sheet capable of providing good concealment to an adherend whose surface to which the PSA sheet is applied has been processed. Provided is a PSA sheet having a PSA layer. The PSA layer has a light transmittance of 20% or lower and an L* value of 20 or higher and 70 or lower, defined in the L*a*b* color space.

Abstract: Provided is a PSA sheet having limited light transmission with reduced PSA-entering light. A PSA sheet having a PSA layer is provided. The PSA layer comprising at least two species of colorants. The PSA layer has a light transmittance of 30% or lower and a light reflectance of 8% or higher.

Abstract: Provided is a pressure-sensitive adhesive sheet which has such light-transmitting properties that the pressure-sensitive adhesive sheet hides an adherend and the surface of the adherend can be inspected through the pressure-sensitive adhesive sheet. The pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer contains at least two colorants. The pressure-sensitive adhesive sheet has a total light transmittance of 5% or greater. The pressure-sensitive adhesive layer has a haze of 20 or greater.
