Abstract (en)
[origin: WO9928133A1] A biaxially oriented polyester film for thermal transfer which is a coated film having a thickness of 20 mu m or smaller and obtained by applying a coating fluid containing a water-soluble or water-dispersible organic polymer to at least one side of a polyester film whose orientation and crystallization have not been completed and then drying, stretching, and heating the film, characterized by having thickness fluctuations of 10 % or smaller in any 15 m range in the machine direction. When an ink ribbon containing this film as a base is used in printing, prints having reduced image density fluctuation can be obtained with satisfactory color tone reproducibility.
