Abstract: Curable adhesive films, primers for adhesion of curable adhesive films, and adhesive systems comprising adhesive films and primers are provided. In some embodiments, an adhesive system comprises: I) a curable adhesive free-standing film comprising a blend of: a) a first film-forming polymer or oligomer; b) a first species comprising first unsaturated free-radically polymerizable groups, which may be a) or a species other than a); and c) a first transition metal cation; and II) a primer for adhesion of a curable adhesive free-standing film to a first substrate comprising an oxidizing agent. In some embodiments, an adhesive system comprises: I) a curable adhesive free-standing film comprising an outer surface bearing embossed air bleed channels capable of aiding in escape of air during application of the outer surface to a primed substrate; and II) a primer comprising components that initiate cure of the curable adhesive free-standing film.

Abstract: An adhesive article comprising first and second tacky latent adhesive layers disposed on respective first and second opposed major surfaces of a substrate. Each of the first and second tacky latent adhesive layers independently comprises at least one polymerizable component, and a redox initiator system comprising a transition metal complex that participates in a redox cycle, an oxidizing agent, and a blocked reducing agent represented by the formula ((I). Each of R1 and R2 are independently H, an alkyl, an aryl, or RPhoto5 with the proviso that at least one of R1 and R2 is RPhoto. RPhoto represents a photoremovable group. Each of R3 and R4 independently represents H, an alkyl group, or an aryl group comprising a monovalent ester, ether, urethane, or carbonate group. Methods of making and using the adhesive articles are also disclosed.
