Hi Kirk,
I wonder,do you have any sugestions as to other dyes, with published structures , that could be used as green and red sensitizers. I know of several candidates from my studies of the Lippman process and pan holography. But some of these dyes are hard to purchase due to company self imposed rules about selling "hazadous" chemicals to individuals.
I would hate to develope a panchtomatic emulsion, then learn that H.W.Sands has decided to discontinue it.
Regards,
Bill
