Abstract: PROBLEM TO BE SOLVED: To provide a composition for production of a crosslinkable pressure-sensitive adhesive for skin, having satisfactory pressure-sensitive adhesion and releasability for human skin, low in irritation, suitable for medical and cosmetic uses, suitable for production, and having superior preservability. SOLUTION: The composition is formed with 100 pts.mass acrylic copolymer (copolymer A) comprising an alkyl (meth)acrylate as a main constituent, and 3-45 mass% diacetone acrylamide as an essential constituent, and containing no free carboxy group, and 0.1-30 pts.mass acrylic copolymer (copolymer B) comprising an alkyl (meth)acrylate as a main constituent and a primary amino group and/or carboxyhydrazide group on a side chain, and containing no free carboxy group. The copolymer B contains two or more primary amino groups and/or carboxyhydrazide groups in one molecular chain, and the primary amino groups and/or carbohydrazide groups in the copolymer B are contained at a ratio of one in 5-100 molecular chains of the (meth)acrylate comonomer.

Abstract: A medical tape preparation which comprises a support and, superposed on one side thereof in the following order, a pressure-sensitive adhesive layer and a release liner. The pressure-sensitive adhesive layer can contain a large amount of an oleophilic oily matter. The tape preparation is excellent in adhesion, cohesiveness, and stability even when no crosslinking agent is used. The pressure-sensitive adhesive layer in the medical tape preparation comprises a blend of two tacky polymers, which are a tacky polymer (A) comprising a copolymer obtained from 2-acetoacetoxyethyl methacrylate and other vinyl monomer(s) as constituent ingredients and a tacky polymer (B) comprising a copolymer which is obtained from a C 4-10 -alkyl (meth)acrylate and other vinyl monomer(s) as constituent ingredients and is different from the tacky polymer (A).
