Opis

Stability is one of the most important performances required for silver halide photographic materials. In 1935, Dr. E. 1. Birr introduced the concept of the stabilization ofphotographic emulsions for the first time by inventing a most effective stabilizer, 4-oxo-6-methyl-l,3,3a,7-tetraazaindene (TAl). Dr. Birr's monograph Stabilization ofPhotographic Silver Halide Emulsions was published in 1974, and accepted as a reliable reference book by many photographic scientists and engineers. Since then, silver halide photographic materials have been greatly improved and expanded through active and continual development of various kinds of technologies. Especially, extensive efforts have been made to develop photographic materials with high sensitivity and rapid processing, which rely upon the stability ofphotographic emulsions under various conditions. Thus, the concept and technologies of stabilization ofphotographic silver halide materials have been expanded so extensively that many photographic scientists and engineers eagerly want a reliable, new reference book on the stabilization of photographic emulsions. Dr. Gunther Fischer is one of the most experienced and eminent scientists and engineers in the field of the stabilization of photographic materials with expanded concept. He has been involved in research on the stabilization of pho- tographic emulsions since 1964 when he joined the Technical Scientific Laboratory in the Research and Development Department of the Photo Film Company Agfa Wolfen formerly headed by Dr. Birr, whom he succeeded in that position. I was deeply impressed by his fruitful and elaborate achievements in these fields.

For more than 150 years silver halide photography has played a dominant role in image recording. Stability of silver halide photographic materials is regarded as one of the parameters governing the quality of this imaging medium.

Since Emil-Joachim Birr’s 1935 discovery of an effective, generally applicable stabilizer, the sphere of emulsion stabilization has markedly extended. These steady efforts are documented in more than 800 articles and 3,260 patents published since 1969 alone.

"Gunther Fischer is extremely knowledgeable about these patents as well as the literature owing to his deep experience in this field [since 1964], and has managed to include all of them in this monograph in good arrangement. I am sure that this monograph will be very useful for photographic scientists and engineers, and will greatly contribute to progress in photographic science and technology."—Tadaaki Tani, The President of the Internationa Committee for Imaging Science and Technology (ICIS), Ashigara Research Laboratories, Fuji Photo Film Co., Ltd.

The book is unique in that it includes stabilizers, not only in the conventional sense, but also from the viewpoint of antioxidants, oxidized developer scavengers, compounds for modifications of grain habit and growth, inhibitions of chemical ripening and development, and development inhibitor releasing compounds.
