Abstract
A polarizing plate protective film contains a compound represented by general formula (II-1) or (II-2). In general formulas (II-1) and (II-2), X represents a 6-membered cyclic acetal group; n represents an integer of 2 or more; and a plurality of Xs may be identical or different. In general formula (II-1), Zrepresents a linking group having a valence of n; Rrepresents a substituent, when there are a plurality of Rs, at least two of the plurality of Rs may be taken together to form a ring, Rs in different benzene rings may be taken together to form a single bond; m represents an integer of 0-4; and the plurality of Rs may be identical or different. In general formula (II-2), Zrepresents an alkylene group having a valence of n, provided that Zdoes not have a ring structure.
