ABSTRACT:
A method of film fabrication is taught that uses a coating and drying apparatus to fabricate resin films suitable for optical applications. In particular, polyvinyl butyral films are prepared by simultaneous application of multiple liquid layers to a moving carrier substrate. After solvent removal, the polyvinyl butyral films are peeled from the sacrificial carrier substrate. Polyvinyl butyral films prepared by the current invention exhibit good clarity and low birefringence.
