Yes I agree, that lengthening would be better, although these chemicals are not the original, so may behave different, although I agree that the longer they are developed, the more dye is formed and may help with the life of the film post-developing.Development must go to completion. If you cut development time, then it might not. This could be quite bad. Reduction of coupler at the same development time will get it to go to completion but with less dye.
At least, that is my reasoning.

Yeah, so maybe you increase the cyan time and decrease the quantity of coupler like PE suggested?Probably lengthening the cyan development time will correct that, and keep the full magenta development as before.
IIRC, you said you had to shorten the cyan development because it was overpowering?
I see what you mean about the reds, but you have made good progress.
Yellows do appear good also.

Your work is very interesting--and the portrait of your shoes is worthy of Van Gogh.
OK, I have an update:
I dont know if PE or anyone can help or not, but I have just been contacted by one of the companies in china regarding the Kodachrome processing chemicals.
They have told me they should be able to produce the chemicals i mentioned, as they have the right intermediate chemicals, but they would like the CAS number for these chemicals.
I dont know if there was even a CAS number registered for these, as these are proprietary chemicals only used by Kodak?
Anyway, they may be able to help, but out of those yellow and magenta couplers in the patent, which ones should we go for?
I also see on the facebook page for the space shuttle film, that he has been working with Kelvin Kittle, but have (not surprisingly) made any progress.

If i have the exact chemical name for each coupler, i will forward this information to China.
If the K-lab can be fired up working with the right chemicals, it would be awesome!
Would also make it a breeze for piratelogy's processing, if we want to replicate K14 as much as possible.
Amazing info Nzoomed!!!
So perhaps the Pirate-K14 process can finally turn into the real K14 process!!
Im hoping you can help me here, is it typical to see pyrazolone couplers for the cyan and yellow layers?I did NOT say to ignore those magenta couplers. I just stated that the structure shown was wrong for one coupler. Almost all magenta couplers today are pyrazolones.

Im pretty confident that only the magenta (for kodachrome anyway) was pyrazolone, is this correct?
If so, a company in china has told me they should be able to make the chemistry, as ive posted above.
They will even make us a small batch, but we will have to pay for the sample.
Or being destroyed?
What else has changed?
