paper presents a simple method for comparing the static resolving power of photographic film and CCD.

Study on production of dioctyl terephthalate from waste sensitive film;

This paper presents a comprehensive outline of the important functions of photographic materials in the State economy and a systematic introducion of the advancement history of the technical progress of photographic materials,including the products technology,production process,support technology,application techniques etc.

In recent years ,the study on the application of fluoro－ surfactants in photographic materials is a new topic of research in the development of photographic materials.

Someday China will be the largest photographic market in the world and the potential for sustained long-term growth is enormous, so world renowned multinational manufacturers of photographic materials crowded to step in the Chinese market, thus inducing an intensified competition in the market of X-ray film in China.

The fast development of processing industry of photosensitive material,produces a large number of photosensitive material wastes,which has caused pollution to the environment seriously,influenced the steady development of the society economy,endangered human health.

A new method of silver nitrate preparation from waste photosensitive materials has studied.

Packaging films for photosensitive materials include inner and outer packaging films.
