PROBLEM TO BE SOLVED: To provide a cellulose acylate film having both hardness and brittleness resistance and excellent in moisture resistance and durability, and excellent in moisture resistance, tear strength and folding strength even for a thin film having a thickness of 80 μm or less. To provide a cellulose acylate film. SOLUTION: A cellulose acylate and a polyester type hyperbranched compound having a hydroxyl group at a terminal, wherein at least a part of the hydroxyl group is selected from -OR 1 group, -OCOR 2 group and -OCONHR 3 group. Containing at least one polyester-type hyperbranched compound (PB) modified with at least one polar group (wherein R 1 , R 2 and R 3 each represents a hydrocarbon group) A cellulose acylate film characterized by comprising: [Selection figure] None |
