    The process of claim 6 in which said yellow color developing composition contains a diffusible acylacetanilide yellow-dye-forming coupler and a color developing agent selected from the class consisting of N-ethyl-N-methoxyethyl-3-methyl-p-phenylenediamine, N-ethyl-N-methoxybutyl-3-methyl-p-phenylenediamine, N-ethyl-N-ethoxyethyl-3-methyl-p-phenylenediamine, N-ethyl-N-methoxyethyl-3-propyl-p-phenylenediamine, N-ethyl-N-methoxyethyl-3-methoxy-p-phenylenediamine and N-ethyl-N-butoxyethyl-3-methyl-p-phenylenediamine.

    Ron , I think below list is ok , I could not find cyan chemicl name . Do you accept the list ?

    cyan coupler is selected from the class consisting of a phenol and a naphthol; said magenta coupler is a 5-pyrazolone coupler and said yellow coupler is an acylacetacetamide.

    yellow :1-Hydroxy-N-(2-acetamidophenethyl)- 2-naphthamide

    magenta :1-(2,4,6-Trichlorophenyl)-3-(p-nitroanilino)-2-pyrazoline-5-one

    cyan :acylamino phenols

    It appears that the dye couplers used in Kodachrome K-14 color developers are listed in the Material Safety Data Sheets for the K-Lab chemicals. These can be viewed here:
    http://www.siri.org/msds/gn.cgi?query=k-lab
    Unfortunately I can't copy and paste right now, or I'd copy the exact dye coupler names. They are quite obvious though.
    Edit: maybe I was too quick; looking deeper doesn't make it seem so obvious at all.

    d235j ,

    Happy New Year and Welcome to APUG.

    Thank you for the tip , They are not obvious for me so the others. So if you know or if you can do something please contribute.

    I will read the notes , I hope I would be sure about my research.

    Thank you and Very good start to Forum.

For stills in a hand tank, alkaline solution + agitation removes almost all of it, traces are left that can be wipe off after the developer stage. I've even run it through developer without removing remjet first, doesn't stick to the film like people say, it's suspended in developer. If you dont intend to keep/reuse the developer, I haven't found a problem with that.. as long as it's not activated carbon I guess.. which may cause potential issues.. though I doubt it over a short developing time.

    That is one of the problems of sustaining any analog product. It takes a huge physical plant and a huge staff of trained people even if you are making small runs.

    The future may be in hand made products, as I have said before.

    That's how much it cost me for Pro 160S in 4x5..

    It is interesting to note that all of the MSDS sheets seem to omit the coupler and other major ingredients. It is also interesting that all of these sheets list CD4 as the Color Developer for the yellow layer, but they use CD6 for the yellow color developer. I'll have to look up the couplers I do have.

    Thank you PE ,

    I banged my head to the same wall.

    Thank you for coupler information promise.

    OK, let me ask a few more questions? To recap first:

    The front side must be protected!

    The red exposure nominally uses a WR70 red filter, and the intensity and time must be such that the other layers are not fogged.

    The blue exposure is also a WR filter, and must be carefully controlled to prevent fogging the green layer.

    PE
    Refined steps below.

    For step 04, do we know the light dose required? And do we know the intensity not to exceed? Is there a lower threshold as well? It seems illogical that one could expose for hours with a very feeble light and expect to get good results.

    Or do these values have be determined experimentally?

    For step 07, is WR47 the correct blue filter? That's the blue color separation filter.

    Likewise, for step 07, do we know the light dose required? And do we know the intensity not to exceed? Is there a lower threshold as well?


    Preliminary listing of mechanical steps.

    01) Warm bath Akaline wash for rem-jet removal (Athiril understands how to do this. The process may need slight improvement to assure complete removal for the red reexposure to be complete. Speckles are not good.)

    01a) Flush to clear clear

    02) develop in E6 1st developer

    03) wash

    04) red reexpose through film base with WR70 filter for X lumen-seconds where lumen(dot) does not exceed Q. Do not allow exposure of emulsion side.

    05) red/cyan develop (Mustafa has tracked down the coupler chemicals, but we don't know exact process yet.)

    06) wash

    07) blue reexpose emulsion side with WR?? filter for Y lumen-seconds where lumen(dot) does not exceed P.

    08) blue/yellow develop (Again, Mustafa has tracked down the coupler chemicals, but we don't know exact process yet.)


    09) wash

    10) fog

    11) green/magenta develop (And again, Mustafa has tracked down the chemicals, but we don't know exact process yet.)

    12) wash

    13-18)then finish with the rest of the E6 process (I'll straighten these steps out later).

    Michael;

    The blue filter must be narrow. I believe it is a WR98. The time and intensity are critical and differ for each of the 3 Kodachrome films, 25, 64 and 200. The Daylight differs from the Tungsten as well. They must be individually determined but once done it will remain constant. I do not have information on this. GWTW. Sorry.
