Patent ID: 7501358

Claim:
An adhesive preparation comprising a support made of a cloth, wherein said cloth is a knitted fabric made of a synthetic fiber, and a pressure sensitive adhesive layer formed on one surface of the support, which comprises a pressure sensitive adhesive and a drug, wherein said pressure sensitive adhesive layer is directly laminated on said cloth, wherein said pressure sensitive adhesive comprises an acrylic copolymer obtained by copolymerization of a monomer mixture comprising (meth)acrylic acid alkyl ester as a main component, wherein said acrylic copolymer is crosslinked with a crosslinking agent, and wherein a mass (CW) per unit area of said support is 60-160 g/m 2 , a ratio (CW/AW) of a mass (CW) per unit area of the above-mentioned support and a mass (AW) per unit area of the above-mentioned pressure sensitive adhesive layer is 1.0-5.0, an adhesive layer-free surface of said support has a static friction coefficient of 0.25-0.75, and a 20% modulus (AM) in one direction of the adhesive preparation and a 20% modulus (EM) in the direction perpendicular to said direction are each 0.5-1.5 N/cm, and the ratio thereof (AM/EM) is 0.5-2.0.
