Abstract:
A cellulose acylate film, which includes a compound denoted by general formula (I) below, the equivalent U of which, calculated as a value obtained by dividing the molecular weight of the compound by the number of divalent linking groups denoted by —O—C(═O)—NH— contained per molecule, is less than or equal to 515, wherein, in general formula (I), each of L11 and L21 independently denotes an optionally substituted alkylene group; each of L12 and L22 independently denotes a single bond, any one of or any combination of —O—, —NR1—, —S— and —C(═O)—; R1 denotes a hydrogen atom or a substituent; each of n1 and n2 independently denotes an integer of 0 to 20, with at least either n1 or n2 being an integer of greater than or equal to 1. Q1-(L12-L11)n1-O—C(═O)—NH-(L21-L22)n2-Q2 General formula (I)
