A film is described comprising a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30 C. to 60 C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.

The present disclosure, in one embodiment, relates to a system and method to transfer material to a substrate. In one embodiment, the system for material transfer includes an adhesive sheet and a transfer material sheet. The adhesive sheet comprises an adhesive, such as ethylene acrylic acid (EAA), ethylene methacrylic acid (EMAA), or ethylene-vinyl acetate (EVA), and a paper release backing. The paper release backing may comprise supercalendered kraft base paper. The transfer material sheet may include a transfer material and a material release liner. The transfer material may be metallized polyester
