Abstract: Pressure-sensitive adhesive compositions and articles that include a layer of the pressure-sensitive adhesive compositions are provided. The pressure-sensitive adhesive compositions are particularly well suited for use with substrates that have been considered to have difficult to bond to surfaces such as those routinely encountered in the automotive industry. For example, the pressure-sensitive adhesive can be adhered to clear coat compositions, painted surfaces, and various polymeric materials having low energy surfaces (e.g., surfaces having a surface energy no greater than 35 dynes per centimeter).
