摘要： Medical pressure-sensitive adhesive sheets having a pressure-sensitive adhesive layer on at least one side of a support so as to have an appropriate tack strength and acceptable processability. The pressure-sensitive adhesive layer is formed with a pressure-sensitive adhesive composed mainly of an acrylic polymer and a compatible component that is compatible with the acrylic polymer. The support layer contains a compatible component that is compatible with the acrylic polymer. The amount of the compatible component contained in the support layer is 70% or less of the amount of the compatible component contained in the pressure-sensitive adhesive layer and the support layer has an elongation of 200% or more without containing any compatible component.

摘要： A substrate film for an adhesive sheet containing an elastomer resin and a hydrophilic polymer having a tensile modulus of elasticity higher than that of the elastomer resin and/or 8 to 100 parts by weight per 100 parts by weight of the elastomer of inorganic fine particles having an average diameter size of 15 &mgr;m or less are added. An adhesive sheet is formed by providing an adhesive layer on the film. The adhesive sheet prepared using the film containing the hydrophilic polymer as a substrate has sufficient flexibility and sufficient skin follow-up property after its application, while sufficiently satisfying processability in producing the adhesive sheet and handling property in adhering. The adhesive sheet prepared using the inorganic fine particles as a substrate has a tensile strength which allows to easily cut the sheet by hands, exhibits an appropriate stress in slight deformation, and is easily handled in adhering, while securing an appropriate slipperiness and barrier property against microorganisms or the like.
