PURPOSE:To improve feeding properties and sticking resistance of a film by providing an oriented liquid-crystal film for thermal transfer having a Young's modulus in longitudinal direction of 500-8,000kg/mm<2> and a center line average surface roughness of 0.008-1.0mum. CONSTITUTION:A polymer having the property of forming an optically anisotropic molten material, such as a wholly aromatic polyester, an aromatic- aliphatic polyester and an aromatic polyazomethine, is blended with about 0.01-5wt.% of an inorganic or organic fine particles inactive to the polymer. The blended polymer material is, for example, melt-extruded through a die slit of an extruder, and is melt-stretched to produce a monoaxially oriented film. The film thus obtained is an oriented liquid-crystal film for thermal transfer which as a Young's modules in longitudinal direction of 500-8,000kg/mm<2> and a center line average surface roughness of 0.008-1.0mum. |
