摘要： A support for an imaging element is described, which support comprises a polyester polymeric film having coated thereon a subbing layer comprising gelatin and a multi-hydric organic compound having at least three hydroxyl groups, which gelatin subbing layer coated support has been subjected to a heat treatment to reduce the core-set curling tendency of the polymeric film. Imaging elements for use in an image-forming process is also described, which elements comprise a gelatin subbing layer coated polyester polymeric film support as described above, and an image-forming layer coated on the subbed support. A method for forming a heat-tempered, gelatin-subbed support for an imaging element is also described, comprising coating a subbing layer comprising gelatin and a multi-hydric organic compound having at least three hydroxyl groups on a polyester polymeric film, and subjected the coated film to heat treatment to reduce the core-set curling tendency of the polymeric film. In accordance with preferred embodiment of the invention, the polymer film comprises poly(ethylene naphthalate), the multi-hydric organic compound comprises glycerol, sorbitol, or pentaerythritol, and the heat treatment comprises subjecting the gelatin subbing layer coated support to a temperature of from 50.degree. C. up to the glass transition temperature of the polymeric film for from 0.1 to 1500 hours.
