Normally tacky and pressure-sensitive adhesive, having excellent long-term adhesion to plasticized vinyl substrates, is prepared from a representative blend of dioctyl phthalate plasticizer and a copolymer of isooctyl acrylate, N-vinyl pyrrolidone, and acrylic acid; alternatives for each component are disclosed. In a preferred embodiment of the invention, the adhesive is coated in a thin layer on a sheet backing material to form a normally tacky and pressure-sensitive adhesive tape. |
