Patent ID: 8906475

Claim:
A cellulose acylate film, which contains a hydrogen-bonding compound satisfying the following requirements (A) to (C), and at least one hydrophobizing agent selected from a polyalcohol ester-base hydrophobizing agent, a polycondensate ester-base hydrophobizing agent and a carbohydrate derivative-base hydrophobizing agent: (A) the compound has both a hydrogen-bonding donor part and a hydrogen-bonding acceptor part in one molecule, (B) the value computed by dividing the molecular weight of the compound by the total number of the hydrogen-bonding donor number and the hydrogen-bonding acceptor number in the compound is from 30 to 65, and (C) the total number of the aromatic ring structures in the compound is from 1 to 3, wherein the hydrogen-bonding compound is a compound represented by the following general formula (E-1): wherein Y1 represents a methine group or —N—; Ra31 represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group; Rb31, Rc31, Rd31 and Re31 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group; Q21 represents a single bond, —O—, —S— or —NRf—; Rf represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group, and may link with Ra31 to form a ring; X31, X32 and X33 each independently represent a single bond or a divalent linking group; X34 represents a linking group selected from divalent linking groups represented by the following general formula (Q): wherein the side * is the linking site via which the formula links with the N atom substituting on the hetero ring in the compound represented by the general formula (E-1).
