Sakuracolor II N100 1974 c84 Employing a DIR color coupler

[Simplicius]

I was given a box of old cameras the other day, mostly junk but opening an old box brownie I discovered an unused spool of Sakuracolor II in 120. So the film is nearly as old as me! looking it up all I can find is

• Sakuracolor II N100 1974-c84 Employing a DIR color coupler

I am of course tempted to shoot this and see what I get. probably at 25iso. Now I see the process is one I have never heard of. If I develop this in C41 will it screw my developer? Or likewise, if I send it to a local lab as C41. Or is my option Stand development in Rodinal? ( I know the realistic option of forgetting it, at that age, nothing is likely to come out but I am logical in my professional life and never in photography )
Thanks in advance.

C84 is the Konica name for a C41 compatible film. It is supposed to be usable.

Thank you ...

A film which is that old will not only lose quite a bit of sensitivity, it will also lose quite a bit of contrast. If you can process C-41 at home and have some home brewing skills, you should think about some contrast boosting procedures (addition of peroxide to CD, developer/rehal bleach/redevelop, ...).

I very much doubt that it contained a DIR coupler.

Such was invented and patented by Kodak and introduced in 1972, setting their films apart. Why should they license such at that stage?

Peroxide will not work on most films. The released inhibitors and the released Iodide will turn off the catalytic effect.

And, both Konica and Fuji did have DIR films at that time. They used both proprietary methods and a license from EK for these couplers.

Thank you! I shall look further into this, as so far I had no hint at all of this kind.
