Abstract: A film comprising in admixture a thermoplastic resin component comprising a thermoplastic resin component and a glass having a refractive index within 0.04 of the thermoplastic resin component, wherein the film has a haze of less than about 20%, total transmittance of greater than about 70%, and a coefficient of thermal expansion of about 20 to about 80 um/m/° C. measured over a temperature range of 20 to 70° C. The films are of particular utility in optical applications such as light diffuser films.
