众所周知,在某些情况下如果在显影液中添加少量有机防灰雾剂,就能使溴化物的防灰雾功能获得增补。特别是对那些基于吡唑烷酮结构的显影液(例如菲尼酮)来说,在高pH值下更需添加这种防灰雾物质,将灰雾降低到一个可接受的水平上。若在高温下冲洗高感光度的胶片,会大大增加灰雾形成的倾向。在这种情况下可借助这类化合物来获得良好的效果,而继续增加溴化物的浓 It is well known that in some cases, the addition of a small amount of an organic anti-fogging agent to a developer can provide an additional protection against fogging of bromides. Especially for those developing solutions based on pyrazolidone structures, such as phenidone, it is even more desirable to add such anti-fogging material at high pH to reduce the fog to an acceptable level. Flushing high-sensitivity films at high temperatures greatly increases the tendency to fog. In this case, good results can be obtained with the aid of such compounds, while the concentration of bromide continues to increase
