    I know about the structure, property and function of the rem-jet layer.


    But what is the meaning/origin of that designation?

    Up to now I could not find an explanation, neither on my bookshelves nor on the net.

    Maybe I'm wrong but from what I remember the term, Rem Jet, refers to the intense spray of water in the processing system that removes the layer. A Jet of water, that Removes the layer.

    Paul,

    After posting I got that idea that `rem´ could be related to `remove´, but still had no idea about that `jet´ part.
    I guess I still would not designate that layer this way, but your explanation makes sense at least.

    I heard once that "Jet" referred to the "Jet Black" carbon that was used in preparing the backing. IDK if it was true or not.

    removable Jet Black layer...

    Makes sense too.

    That `remove´ part would definitely make sense as other layers of that function are just decoloured in one way or another .

    Funny though that this designation seems a bit mysterious.

    I have a few rolls of exposed Kodak 5247 (rem jet movie film) loaded in 35mm cannisters I shot, but never processed since 1980. (yes, 28 years old!!)

    Anyone know where this stuff can get processed now? I think it is still C41 but that backing will come off and gum up regular processors.

    It's not C-41, it's ECN-2. If you can get the Rem Jet off, you can process it C41, but it will look cross processed. Latent images on MP film that old will likely be gone towards blue and have developed some grain, so I'd stick to normal. The best lab I have experience with is Ford in Seattle. They were bought out by AphaCine, and now the techs are there. I had my last ECN project (Sept.) processed by them, and all was well.

    Here is their website:

    There was an ECN process in the 60s that I have the formulas for, but it was changed for the more recent flavors. IDK when the changeover took place.

    Maybe a dumb question, but are there any c-41 movie films? Or films that can be run through c-41 (i.e. no rem_jet backing)? I have been curious about this for awhile.

    When was remjet invented? Probably before Kodachrome?

    The word always remind me of "ramjet", those special aircraft jet engines without motors. "ramjet" dates from 1942 according to the Merriam-Webster.

    It was invented for Motion Picture. The high transport rates through the camera create a high level of static electricity. At least, that is my take on this.

    Patrick, I have an old question too.
    Do you still have that package of Gevaert paper you mentioned eons ago?

    ... and carbon being a metaloid (conductor of sorts) ...

    Makes sense.

    Patrick,

    All print films made by Agfa and by Kodak do not have a rem-jet layer any longer.

    (Both companies have got their own type of lasting anti-static coating.)

    Well the only reference I know of would be to a SMITH & WESSON handgun cartridge invented in the early 1960's. It was a bottle-necked style and had problems backing out the brass when the gun was fired, locking things up. For that reason it had a very small following. If chambers were kept dry ' no oil' and the brass was dry, they worked fine. Long out of production, they are mostly collector items these days, except those of use who use them. :smile:
    Here is mine, and yes, those are old Ivory stocks. The inserts you see in the photo are put in the chamber and use to fire .22 Long Rifle Cartridge's.:smile:
    ca. 1961 , a first year gun. :smile:
