Acrylic polyvinyl acetal films comprising a second layer

A film is described comprising a first film layer having a Tg ranging from 30 DEG C to 60 DEG 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 th...

Beschreibung
Zusammenfassung:	A film is described comprising a first film layer having a Tg ranging from 30 DEG C to 60 DEG 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 backingsuch as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer. 本发明描述了种膜，所述膜包括具有在30℃至60℃范围内Tg的第膜层。所述第膜层包含(甲基)丙烯酸类聚合物和聚乙烯醇缩醛聚合物组合物。所述膜还包括靠近所述第膜层的第二层。所述第二层不同于所述第膜层。所述第二层可以是固化的(甲基)丙烯酸类聚合物膜或涂层；背衬诸如热塑性聚合物、织造或非织造织物、金属箔、纸、泡沫；或覆盖膜诸如含氟聚合物。
