A film is described comprising a (meth)acrylic polymer and polyvinyl acetal polymer composition, wherein the film comprises a structured layer.

Acrylic films comprising a structured layer

A film is described comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; 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.

Acrylic polyvinyl acetal films comprising a second layer

A graphic film is described comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer. In typical embodiments, the graphic film further comprises a design, image, graphic, or text. Also described is a method of forming a graphic film comprising providing a film comprising a first film layer having a Tg ranging from 30&#xb0; C. to 60&#xb0; C. comprising a (meth)acrylic polymer and polyvinyl acetal polymer and providing a graphic proximate the film.

Acrylic polyvinyl acetal graphic films

A film is described comprising a (meth)acrylic polymer and polyvinyl acetal polymer composition. A layer of an adhesive composition is disposed proximate the film. The adhesive composition has a tensile elastic modulus of less than 1 MPa at 25&#xb0; C. and 1 hertz.
