摘要
PA接枝明胶可用作沉降剂以制备浓缩感光乳剂。本文研究了其在制备黑白全色照相胶片乳剂中的作用,并与其他几种沉降剂,如:聚苯乙烯磺酸盐(F-11)、苯乙烯顺丁烯二酸酐树脂(苯丁树脂),作了对比。试验结果表明,PA胶优于其它几种沉降剂,尤其是在照相性能和与其它明胶的互容性方面。
PA(Phthalic Anhydride) branched gelatin can be used as a flocculating agent for the preparation of highly concentrated silver halides photographic emulsions.This paper reports a study of its behavior in the preparation of black-and-white panchromatic photographic emulsions,compared with other flocculating agents,e.g.sodium polystyrene sulfonate(F-11),styrene-maleic anhydride copolymer etc..Results showed that PA branched gelatin performs much better than other ones,especially regarding the photographic properties of prepared emulsion and the compatibility with other gelatins.
