  • Patent number: 6808770
    Abstract: A heat-resistant film includes a film substrate and a heat-resistant slip layer. The heat-resistant slip layer is disposed on one surface of the film substrate and contains a binder and a slip additive, which is a higher fatty acid metal salt composition containing a free higher fatty acid in an amount of 3 to 30 wt % and a metal salt of a higher fatty acid. With this heat-resistant film, a good heat-resistivity and slipperiness are obtained even when the slip additive is contained in the heat-resistant slip layer in relatively small amounts. The slip additive improves the solution stability of the coating composition used to form the heat-resistant slip layer. Preferably, the free higher fatty acid is stearic acid and the metal salt of higher fatty acid is aluminum stearate.
