ABSTRACT:
Disclosed herein are light diffusing films, methods of making the same and articles using the same. In one embodiment, a light diffusing film is formed from a composition comprising: a polycarbonate, phosphite stabilizer, epoxy stabilizer, hindered phenol stabilizer, and light diffusing particles having a refractive index of about 1.3 to about 1.7. The film comprises a hiding power of 0 to about 0.5. In one embodiment, a method for producing a film comprises combining a polycarbonate, a phosphite stabilizer, an epoxy stabilizer, and light diffusing particles to form a combination, and forming the combination into the film.
