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-alkyl (meth)acrylate and other vinyl monomer(s) as constituent ingredients and is different from the tacky polymer (A).
