    Abstract: A film containing a cellulose acylate, a hindered amine compound at least 0.001% by mass relative to the cellulose acylate, and a plasticizer, satisfying: (i) the concentration C1 of the hindered amine compound 3 μm from the first film surface is higher than the concentration C2 3 μm from the second film surface; (ii) the concentration A of the plasticizer 3 μm from the first film surface is lower than the concentration B 10 μm from the first film surface; (iiia) the 15 acyl substitution degree a of the cellulose acylate 3 μm from the first film surface is lower than the acyl substitution degree b 10 μm from the first film surface; and (iiib) the 20 weight-average molecular weight Ma of the cellulose acylate 3 μm from the first film surface is higher than the weight-average molecular weight Mb 10 μm from the first film surface.

    Abstract: An optical film, containing a cellulose acylate, and at least one compound represented by any of formulas (I) to (III): wherein, in formulas (I) to (III), R1 and R2 each independently represent a halogen atom, an alkyl, cycloalkyl, alkenyl, aryl, hydroxy, hydroxyamino, amino, alkylamino, arylamino, alkoxy, aryloxy, alkylthio, or arylthio group (however, R1 and R2 do not represent an amino, alkylamino, or arylamino group at the same time); R3 to R6 each independently represent a hydrogen atom, an alkyl, cycloalkyl, alkenyl, aryl, acyl, alkyl- or aryl-sulfonyl, alkyl- or aryl-sulfinyl, carbamoyl, sulfamoyl, alkoxycarbonyl, or aryloxycarbonyl group; R7 represents an alkyl, cycloalkyl, alkenyl, aryl, alkylamino, arylamino, alkoxy, aryloxy, or heterocyclic group; R8 represents an alkyl, cycloalkyl, alkenyl, aryl, or heterocyclic group; and R1 to R8 each may be further substituted with a substituent; and a polarizing plate and a liquid crystal display.
