PROBLEM TO BE SOLVED: To provide a cellulose acylate film excellent in surface state, moisture proofness (moisture content) and film strength. SOLUTION: In a cellulose acylate film comprising a mixture of at least two cellulose acylates, there is used a mixture of a cellulose acylate A, wherein the total acyl substitution degree is 2.70-2.90, the 3-22C acyl substitution degree is 0.40-2.50, and the 6-position acyl substitution degree is less than 0.90, and a cellulose acylate B, wherein the total acyl substitution degree is 2.75-2.90, the 3-22C acyl substitution degree is 0.00-0.40, and the 6-position acyl substitution degree is 0.90 or more. |
