主权项 1. A cellulose acetate film, comprising at least one retardation inhibitor selected from compounds represented by Formula 1: (wherein, in Formula 1, R1, R2 and R3 are each independently selected from: hydrogen; (C1-C10)alkyl; (C6-C20)aryl; (C3-C20)cycloalkyl; (C2-C7)alkenyl; (C6-C20)ar(C1-C20)alkyl; 5- to 7-membered heterocycloalkyl containing at least one element selected from N, O and S; and (C4-C20)heteroaryl containing at least one element selected from N, O and S; wherein alkyl, aryl, cycloalkyl, alkenyl, aralkyl, heterocycloalkyl and heteroaryl described above may be further substituted with at least one selected from: (C1-C7)alkyl; halogen; nitro; cyano; hydroxyl; amino; (C6-C20)aryl; (C2-C7)alkenyl; (C3-C20)cycloalkyl; 5- to 7-membered heterocycloalkyl containing at least one element selected from N, O and S; or (C4-C20)heteroaryl containing at least one element selected from N, O and S; and wherein R2 and R3 may be linked together by (C2-C10)alkylene substituted or unsubstituted with (C1-C7)alkyl and/or (C6-C12)aryl, to form an alicyclic ring).
