Abstract

Cinematographic materials, photographic films constituted by polymeric supports and emulsions, on which images and sounds are recorded, are industrial products that have not been specially designed for its storage and conservation as cultural heritage. In this paper the story of these materials are briefly described together with the chemical and biological processes that origin their degradation. It is pointed out that, only thought the scientific research it will be possible to develop theoretical and practical tools to conserve the cinematographic heritage.
