Abstract: An adhesive composition may include at least about 2 wt. % and not greater than 49 wt. % of a (meth)acrylic based polymeric component A for a total weight of the adhesive composition, at least about 51 wt. % of a (meth)acrylic based polymeric component B for a total weight of the adhesive composition, and at least about 0.1 wt. % and not greater than about 30 wt. % of a tackifier component for a total weight of the adhesive composition. The (meth)acrylic based polymeric component A may have a glass transition temperature (Tg) of at least about 40° C. The (meth)acrylic based polymeric component B may have a glass transition temperature (Tg) of not greater than about 20° C. Further, the (meth)acrylic based polymeric component B may be acid-free.
