Abstract
Polyester pressure-sensitive adhesives are described. The polyester includes at least two different diacid residues and at least two different diol residues. The polyester includes at least one pendant group containing an alkenyl group. A ratio of a total number of the at least one pendant group to the total number of ester groups in the polyester is in a range of 0.001 to 0.1. The polyester has a glass transition temperature in a range of −50° C. to −10° C.
