In the case where dicing or the like is performed by performing adsorption fixation to a fixing base with a negative pressure, the occurrence of excessive close adhesion due to, for example, the heat generation of the base can be effectively suppressed. In addition, the non-pressure-sensitive adhesive layer is provided on the base material film, and hence blocking in a roll shape is effectively suppressed, the film for a pressure-sensitive adhesive tape does not tear or break upon its unwinding from the roll shape, conformity between the non-pressure-sensitive adhesive layer and the base material film is good, and followability to a deformation such as stretching is good. Also provided is a pressure-sensitive adhesive tape including such film for a pressure-sensitive adhesive tape.

Abstract: An adhesive patch for external use which is significantly inhibited from causing a rash, is less irritative to the skin, and sufficiently retains adhesion to the skin. The adhesive patch is characterized by employing a pressure-sensitive adhesive base into which a sucrose fatty acid ester has been incorporated. It does not exert physical influences on the skin, such as stresses imposed on the skin during wear and upon peeling, while sufficiently retaining adhesion to the skin. It is significantly inhibited from causing a rash, and the skin irritation thereof has been minimized. This adhesive patch for external use has ideal, lowly irritative properties which have been impossible to any conventional adhesive patch for external use.
