Process for rapid annealing of a polyester film base to control film curl

摘要

A high-CHDM PET-based support for an imaging element can be annealed relatively rapidly to achieve acceptable core-set and post-process curl properties. The fast annealing response of this material allows effective in-line annealing of the film support, yielding a more efficient manufacturing process with less annealing-induced defects in the imaging support.
