Abstract
An acrylic emulsion pressure sensitive adhesive composition is provided. The acrylic emulsion pressure sensitive adhesive composition, due to pH-dependent properties, exhibits stable adhesion when attached to an adherend, but when it needs to be removed, it can be easily removed without residue using an alkaline solution. Thus, if the acrylic emulsion pressure sensitive adhesive composition is used as a pressure sensitive adhesive for a label of a plastic packaging article, the label can be easily removed during a recycling process, thus improving recycling efficiency.
