Abstract
An interlayer comprising a first polymer layer, a polarization rotary optical film and optionally a second polymer layer, and multiple layer panels formed from such interlayers. The panels may exhibit desirable optical properties, including, for example, less image “ghosting,” when used as part of a heads-up-display (HUD) display panel for use in automotive and aircraft applications.
Claims20
An interlayer comprising:
- a first polymer layer comprising a poly(vinyl acetal);
- a polarization rotary optical film;
- and
- a second polymer layer comprising a poly(vinyl acetal);
- wherein the optical film is disposed between the first polymer layer and the second polymer layer, and
- wherein the optical film has a first barrier coating on a first side in contact with the first polymer layer and a second barrier coating on a second side in contact with the second polymer layer.
