Abstract:
1. 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, and further satisfies that a C log P value of the hydrogen-bonding compound is from 0 to 5.5, wherein the hydrogen-bonding compound is a compound represented by the following general formula (A-1): wherein Ra represents an alkyl group, an alkenyl group, an alkynyl group, a heterocyclic group or an aryl group; X1 and X4 each independently represent at least one selected from divalent linking groups represented by the following general formula (P): wherein the side * is the linking site via which the formula links with the N atom substituting on the 1,3,5-triazine ring in the compound represented by the general formulae (A-1); X 2 and X 3 each represent a single bond; R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group.
