Abstract
A new polyimide film which contains 30 to 800 ppm of titanium based on the weight of the film, and a process for producing a new polyimide film which comprises introducing an organic titanium compound substance into the film-forming polyimide resin prior to the casting step. This process enables one to control the film surface forming process and improve directly the adhesive properties of the film.
