摘要

A precursor film for a ceramic film of not more than 1 mm in thickness containing (a) a polymer material and (b) an organometal compound, a hydrolyzed product thereof or a mixture thereof at a metal content of not less than 5% by weight, which can provide an useful functional ceramic film. The precursor film can be prepared by dissolving or dispersing the components (a) and (b) into a solvent, applying the solution to a substrate and removing the solvent.
