<p>PURPOSE: A cellulose acylate film is provided to be easily soluble in cellulose acylate, to have a low light-scattering property, and to minimize the crystallization of an additive after elongation. CONSTITUTION: A cellulose acylate film comprises an additive which has a liquid phase at room temperature, a melting point of (-50) to 50°C, a boiling point of 300°C or more, and an inherent refractivity of 1.4-1.6. The additive is selected from a chemical formula 1: R1-(R3)a-L1-(R5)b-(L2)c-(R4)d-R2. In chemical formula 1, R1 is selected from (C1-50)alkyl, (C6-20)aryl, (C3-20)cycloalkyl, (C2-7)alkenyl, (C6-20)ar(C1-20)alkyl, (C1-50)heteroalkyl, heterocycloalkyl, and (C4-20)heteroaryl; each of L1 and L2 is a connecting group which is selected from an ester group, an amide group, an ether group, a urea group, a thioester group, a carboxy group, and a carbamate group.</p> |
