(57) [Summary] [Structure] A pressure-sensitive adhesive tape, sheet or sheet having a pressure-sensitive adhesive layer containing microspheres and a surfactant selected from a fluorine-based surfactant and a silicon-based surfactant. An active energy ray-curable composition comprising a label, a (meth) acrylic acid alkyl ester used for the label, microspheres, and a surfactant selected from a fluorine-based surfactant and a silicon-based surfactant. [Effect] It is possible to produce a pressure-sensitive adhesive tape, sheet or label having excellent adhesiveness and shape conformability to uneven surfaces without impairing cohesive strength, heat resistance and workability. |
