Claims22
A graphic film article comprising:
- a conformable, extruded film layer comprising a polymer blend comprising a first polymer comprising only thermoplastic polyurethane and a second polymer comprising polyvinyl butyral, wherein the film layer is outdoor weatherable, the film has a first major surface and a second major surface opposite the first major surface, and at least one major surface is an exposed imageable film surface at least partially defined by the polymer blend that can receive an ink layer.
A graphic film article comprising
- a conformable, extruded film layer comprising a polymer blend comprising a first polymer comprising only thermoplastic polyurethane and a second polymer comprising polyvinyl butyral;
- an adhesive layer on a first major surface of the film layer;
- and
- an exposed imageable surface at least partially defined by the polymer blend that can receive an ink layer on a second major surface of the film layer opposite the first major surface;
- wherein the film layer further comprises a polyester plasticizer.
