油溶性染料用于银漂感光材料研究

Application of oil-soluble dyes in silver dye bleachin photographic materials

将１１种油溶性染料（其中黄色６种、品红３种、青色２种）应用于银漂感光材料中，研究了各染料在不同高沸点溶剂中对色光、漂白性、感光性等的影响，发现含芳香基为主的染料在ＴＣＮ（磷酸三甲苯酯）中、含脂肪长链的染料在ＴＢＰ（磷酸三丁酯）中具有较好的应用性能；ＴＢＰ、ＤＢＰ（邻苯二甲酸二丁酯）中染料的漂白速度高于ＴＣＰ．Ｙ－２、Ｍ－１、Ｃ－２等品种性能较好。

Eleven oil soluble dyes(including 6 yellow,3 magenta and 2 cyan dyes)are used insilver dye bleach photography. The influence of the dyes and their dissolving solvents on color,bleaching properties and light-sensibilities of the photographic materials are studied. For a dyewhich contains more aromatic and less aliphatic groups,TCP(tricresy phosphate) is a suitablesolvent.But long- aliphatic-group- containing dyes are preferable to DBP(dibutyl phthalate)andTBP(tributyl phosphate),Dyes in TBP and DBP are easier to be bleached than in TCP,In thedyes,Y-2,M-1and C-2 have the best photographic properties.
