Abstract

A film is described comprises a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. The film has a tensile elastic modulus of at least 1 MPa at 25° C. and 1 hertz and a glass transition temperature (i.e. Tg) less than 30 C. The film typically comprises photoinitiator as a result of the method by which the film was made. In one embodiment, the film is heat bondable and further comprising a backing.
