The company has refused to give me any data on these dyes, merely to tell me that they are green sensitizers. By testing, I found that one is a red sensitizer and had this confirmed by Paul Gilman, the Kodak expert on dyes. Sorry I cannot help you with structures. I have one partial ID on the red sensitizer. It is used in Kodachrome film!

They are generically probably cyanine dyes.

I have used both, but since the one marked green is really a red, I have fogged all emulsions eventually when using it due to my trusting nature. (BTW, it is a green sensitizer on Chloride and Bromide emulsions but not on Bromo Iodides due to J aggregate formation.)
