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.

Study on Cr_2O_3-Al_2O_3 sensitive materials for CH_4 gas

The sensitivity and selectivity of chemical sensors are controlled by sensitive materials mainly.

Research in screening of molecularly imprinted polymer sensitive materials with combinatorial chemistry is reported,from 25 candidate polymers,a novel molecularly imprinted polymer with great selectivity is screened out.

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.

Research progress of photosensitive materials applied in electrophotography;

Applying KDD(Knowledge Discovery in Databases) technology in data analysis is helpful to improve data-analysis ability and productivity in photosensitive materials enterprises.
