发明名称 ADHESIVE COMPOSITION FOR MEDICAL USE, PATCH FOR MEDICAL USE, AND METHOD FOR PRODUCING THE COMPOSITION
摘要 An adhesive composition for medical use of the present invention includes an acrylic copolymer, a medicament having a carboxyl group, and a base, the acrylic copolymer is prepared by copolymerization of a monomer mixture containing 0.1 to 2 mass % of an ethylenically unsaturated carboxylic acid monomer as a monomer A, 58 to 99.9 mass % of an alkyl(meth)acrylate ester having an alkyl group of 4 to 12 carbon atoms as a monomer B, 30 mass % or less of an alkyl(meth)acrylate ester having 1 to 3 carbon atoms as a monomer C, and 30 mass % or less of a monomer having an ethylenically unsaturated group other than those of the monomers A to C (the total of monomers A to D is taken as 100 mass %) as a monomer D, and the content of sulfuric acid in the acrylic copolymer is 700 ppm by mass or less.
