Patent ID: 7119140

Claim:
A film comprising in admixture: a thermoplastic resin component comprising a polycarbonate; and a glass having a refractive index within 0.04 of the thermoplastic resin component, wherein the glass is essentially free of compounds selected from the group consisting of aluminum oxides, boron oxides, boric acids and a combination comprising at least one of the foregoing; wherein the glass has been passivated with a passivating agent containing a silicon hydride functionality, wherein the passivating agent is of the formula (10) or (11); wherein m is greater than or equal to 1; the sum of m and n is equal to 1 to 10,000; m+p is 3 to about 1,000; R g and R i are each independently hydrogen, alkyl, aryl, alkylaryl, alkoxy, aryloxy, haloakyl, haloaryl, and haloalkylaryl; R j and R k are each independently alkyl, aryl, alkylaryl, alkoxy, aryloxy, haloalkyl, haloaryl, and haloalkylaryl; and R h is trialkylsilyl, arylalkysilyl, triarylsilyl, hydrogen, alkyl, aryl, alkylaryl, haloalkyl, haloaryl, or haloalkylaryl; wherein the passivating agent is present at about 0.001 to about 1.0 wt. % of the film; wherein the film has a thickness of about 0.01 to about 3.0 mm; and wherein the film composition has a haze of less than about 20%, a total transmittance of greater than about 70%, and a coefficient of thermal expansion of about 20 to about 70 um/m/° C. measured over a temperature range of 20 to 70° C.
