    • A cellulose ester film which can be melt cast is manufactured by esterfying cellulose to form a cellulose acetate or cellulose acetate propionate having degrees of substitution of DSac=1.9 to 2.6, DSpr=0 to 0.9 and DS.sub.OH =0 to 0.55 and melt compounding the resulting polymer with a non-volatile phosphoric acid ester. A film is formed by melt extruding the compounded polymer onto a cooling surface to form a solid film. The film is then biaxially oriented at 130.degree. to 200.degree. C. and a stretch ratio of 1.25.times. to 2.5.times. in both directions. The resulting product is a film of excellent properties such as surface smoothness, light transmission, low haze, low color, high elastic modulus and curl relaxation after aqueous processing. The melt cast film is useful as a photographic roll film to replace solvent cast cellulose triacetate.
