    摘要: The present invention relates to a cellulose acylate film having a high modulus of elasticity and a high surface hardness. The cellulose acylate film of the present invention is characterized by containing 1 vol % to 99 vol % of a metal oxide having an average particle size of 1 nm to 400 nm. The metal oxide used here is preferably a metal oxide having a Mohs hardness of at least 7, and specific examples thereof include aluminum oxide and silicon dioxide. This metal oxide may be subjected to a surface treatment. Furthermore, a functional thin film such as a hardcoat layer may be formed on the cellulose acylate film containing the metal oxide.
