菁染料J-聚集态的感光活性

Photographic activity of J-aggregated state of cyanine dyes

以J-聚集态染料限制空穴自减感作用的设想为基础。研究了感光层自减感的抑制方法及超增感(超敏化)的方法,特别注意的是指示出了超增感“隔离”机理和J-聚集调节方法。

Based on the concept of the restriction of self-desensitization of holes by J-aggregates of cyanine dyes, the author carried out a study on the method for inhibiting the self-dcsensitiza-tion of photographic layers and means for their supersensitization. Most remarkably, he presented an 'isolation' mechanism of supersesitization and means for regulating J-aggregates.
