Abstract: The present invention makes a water-dispersed PSA composition capable of forming a PSA that exhibits good adhesiveness to a non-polar adherend such as polyethylene and polypropylene at a low temperature. The water-dispersed PSA composition comprises a (meth)acrylic polymer obtained by polymerizing a monomer composition comprising as a primary component an alkyl (methacrylate having an alkyl group with 1 to 18 carbon atoms, and a latex containing a rubber component that is immiscible with the (meth)acrylic polymer, the (meth)acrylic polymer and the latex being mixed at a weight ratio ((meth)acrylic polymer/rubber latex) within a range of 95/5 to 25/75 based on solid contents; wherein a storage modulus in a range of-15 °C to 25 °C is I MPa or smaller, the storage modulus being determined by a dynamic viscoelastic measurement in which shear strain is applied at a frequency of 1 Hz, the measurement being taken with respect to the water-dispersed PSA composition dried at 100 °C for 3 minutes.

Abstract: In the method for producing a medical pressure-sensitive adhesive tape or sheet of the invention, a water dispersion-type copolymer solution having a specific composition is used. Therefore, the problem caused by high thixotropy can be eliminated and a pressure-sensitive adhesive layer can be relatively easily formed on a porous substrate by a direct method. In addition, when the medical pressure-sensitive adhesive tape or sheet obtained by the method of the invention is attached to the skin surface, skin adhesion and tube fixing are excellent and at the same time, irritation to skin is low.
