Abstract
A single-layered acrylic pressure-sensitive adhesive tape having a pressure-sensitive adhesive layer formed of an acrylic pressure-sensitive composition. The acrylic pressure-sensitive adhesive composition contains an acrylic polymer (A) and a (meth)acrylic polymer (B) having glass transition temperature (Tg) such that Tg≦45° C. and a mass average molecular weight (Mw) is such that 1500≦Mw≦4000.
