Patent ID: 8420187

Claim:
A cellulose acylate composition comprising at least one cellulose acylate having an aromatic group-containing acyl group (Substituent A), in which the substitution degree with Substituent A satisfies following relational expressions (I) and (II): DSA 2 +DSA 3 −DSA 6>0.05, (I) 0.11 <DSA 2 +DSA 3 +DSA 6<0.71, (II) wherein DSA2, DSA3 and DSA6 each indicates the substitution degree with Substituent A at the 2-, 3- and 6-positions of the cellulose acylate, respectively; and the cellulose acylate satisfies following relational expression (III): 2.9 ≦DS≦ 3.0 (III) wherein DS indicates the total substitution degree of the cellulose acylate.
