1. An adhesive article comprising:
a first carrier layer with a first major surface and a second major surface; and
a first polyester-based ionomeric adhesive layer with a first major surface and a second major surface, wherein the first major surface of the first polyester-based ionomeric adhesive layer is in contact with the second major surface of the first carrier layer, and
wherein the polyester-based adhesive layer comprises:
a polyester composition comprising the reaction product of a reaction mixture comprising:
at least two different diacids;
at least two different diols;
wherein at least one diacid or diol has at least one pendant ethylenically unsaturated group, and
wherein at least one diacid or diol has at least one pendant ionic group;
wherein the polyester composition has a glass transition temperature in a range of 60° C. to 12° C., and
wherein the polyester composition is a vibration-damping, pressure sensitive adhesive, and further comprising a film substrate with a first major surface and a second major surface, wherein the second major surface of the first polyester-based ionomeric adhesive layer is in contact with the first major surface of the film substrate.
