An adhesive composition is described comprising at least one cyclic imide monomer comprising an unsaturated carbonyl. The adhesive composition is a polymerizable composition or a polymerized composition. The polymerizable adhesive composition may comprise at least one monomer, oligomer, polymer, or a combination thereof comprising ethylenically unsaturated groups and/or an epoxy resin. The cyclic imide monomer may comprise an imide group with an , -unsaturated carbonyl in a heterocyclic ring wherein the ring comprises at least 6 covalently bonded atoms. Also described are methods of forming an adhesive coated substrate and articles.
