Abstract: PURPOSE: Provided are an optical film having good thermal stability even without adding any cross-linking agents, and a manufacturing method thereof. CONSTITUTION: The optical film is manufactured by the method comprising the steps of dissolving a cholesteric ionomer represented by the formula 1 into an organic solvent, coating, and then drying or extrusion molding by heat. In the formula 1, each of R1, R2 and R3 is independently H or CH3, R4 is a structure substituted by a mesogenic group, R5 is a chiral substituent, R6 is H or a structure substituted by carboxy group, in which 1-99% of H or carboxy group is substituted by a monovalent or divalent metal salt such as salt of Na, K, Li, Ca, Mg, Co, Zn, Cu or Hg, m is 0.3-0.7, n is 0.1-0.29 and o is 0.01-0.6, provided that the sum of m, n and o is 1. The several sheets of such optical film are overlaid and are compressed to prepare a multi-layer cholesteric film.
