The present invention provides a cellulose acetate film having excellent tear strength, folding strength, excellent optical properties, and long-term storage stability, and an optical film, a polarizing plate, an optical compensation film, and a liquid crystal display device obtained by using the cellulose acetate film. I will provide a. A cellulose acylate film formed by a solution casting method contains cellulose acylate, a polymerizable group-containing monomer (A), a photothermal conversion agent (IR), and a thermal polymerization initiator (I). A cellulose acylate film produced by a process including a casting process for casting a cellulose acylate composition and a near infrared irradiation process. [Selection figure] None |
