Polyester pressure-sensitive adhesives are described. The polyester includes at least two different diacid residues and at least two different diol residues. The at least two different diacid residues include, based on the total moles of the at least two diacid residues, 20 to 80 mole percent of a residue of at least one aromatic dicarboxylic acid, and 20 to 80 mole percent of at least one of a residue of adipic acid or sebacic acid. The polyesters may include at least one pendant group containing an alkenyl group.
