ABSTRACT:
A salt of an uncrosslinked copolymer of a monoethylenically unsaturated mono- or dicarboxylic acid and an alkyl ester of acrylic or methacrylic acid is suitable as a pressure-sensitive skin adhesive for plasters, for transdermal pharmaceutical forms, or for fastening bandages, which is permanently flexible and can be washed off with water, for which the proportion of carboxylic acid has to be sufficient to make the copolymer water-soluble in the salt form.
