ABSTRACT:
Unsupported pressure sensitive adhesive (PSA) films of tacky, polymeric microspheres are provided. The opposite major surfaces of the film provide different levels of peel adhesion, allowing for removability without substrate damage. In addition, the PSA films provide high shear strength and good tensile properties.
