CELLULOSE ACYLATE FILM, NOVEL COMPOUND, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

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)

1. A cellulose acylate film,
which comprises a compound denoted by general formula (I) below, wherein the equivalent U of the compound, which is 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:
Q1-(L12-L11)n1-O—C(═O)—NH-(L21-L22)n2-Q2  General formula (I)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;when L11, L12, L21, and L22 are present in a plurality of number, the plurality of L11, L12, L21, and L22 can be identical or different;and each of Q1 and Q2 independently denotes a substituent, with at least either Q1 or Q2 comprising a ring structure.
