Abstract:
A film is described comprising a first film layer having a Tg ranging from 30° C. to 60° C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.
