    Yes im allso happy that Wayne is getting feedback from Wynit and others ..
    It made me think of a company called Dye Chrome Research in Florida,back in the 90's that had their own mix of Ciba chems .. Something like K1 & K2,
    different temps. Ctein mentions it in his book Post Exposure. I only wish we could convince Wynit to sell to us through some kind of co-op large or small orders..Im afraid that if something dont happen soon we wont be seeing Illfochrome any more. I wonder if they still make a 20l kit.. I called Freestyle this week and they seem like they dont even want to talk about it. I will be calling OJI Ilford USA nexk week. John

    No, it is a phenazine or similar quinoline derivatives. I have a whole patent full of them. All I have to do is find the patent, but to date, no luck.

    The basic reactant has a molecular formula of C4N2H4. Other derivatives put an additional C4 ring on this and some have -OH added to the ring. This venue is not good for organic chemistry structures.
