Abstract: Curable adhesive free-standing films and adhesive systems comprising such films are provided. In some embodiments, a curable adhesive free-standing film comprises 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); c) a first transition metal cation; d) a reducing agent; and no oxidizing agent. In some embodiments, an adhesive system comprises: I) a first curable adhesive free-standing film as described preceding; and II) a second curable adhesive free-standing film comprising a blend of: e) a second film-forming polymer or oligomer; f) a second species comprising second unsaturated free-radically polymerizable groups, which may be e) or may be a species other than e); and g) an oxidizing agent. In some embodiments, the curable adhesive free-standing films may be pressure sensitive adhesives prior to cure. Methods of use are provided.

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 R 1 and R 2 are independently H, an alkyl, an aryl, or RPhoto5 wlth the proviso that at least one of R1 and R 2 is RPhoto. R Photo represents a photoremovable group. Each of R 3 and R 4 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.

Abstract: A core-sheath filament having a non-tacky sheath and a hot-melt processable adhesive core, the sheath exhibiting a melt flow index of less than 15 grams per 10 minutes, is provided. Methods of making the core-sheath filament and methods of using the core-sheath filament to print a hot-melt processable adhesive onto a primer-treated substrate surface to provide a structural bond are described.
