I don't print RA4 paper anymore but want to shoot colour c41 film for scanning and possibly b&w wet printing.

It would be nice if your could buy colour c41 film without the orange mask.

Please NOTE I said colour neg film, not b&w c41 film.

Have you considered Rollei Digibase CN200 (the CN is for Color Negative).

Made by Agfa, but production has been cancelled. So the Rollei-branded conversions would be the last stock.

Kodak Aerocolor, and some other technical films.

The last consumer color negative film without mask was Svema DS-4, but it was not C-41 and it was discontinued about 1995.

If you can't find any maskless color negative film, you can try this:

https://www.photrio.com/forum/index.php?threads/e-6-without-reversal.60835/

Use E-6 film and process like this using E-5 chemicals:

1. First Developer (B&W negative or paper Developer can be used);
2. Fixer;
3. Bleach;
4. Re-exposure;
5. Follow E-6 process from Color Developer on to the end.

It will be more expensive and a lot more difficult to do, but will yield color negatives without a mask.

(Then you can sandwich them with a piece of bleached color negative film and make enlargements on RA-4 paper!)

Cheers,
Flavio

Can't find the "edit" button... I meant "E-6 chemicals", not "E-5". Good this is there was ever an E-5 process.

Eric:
I am curious why you think such a film would be advantageous, unless you were trying to do black and white prints from it.
The colours would be reversed, so such a film would be no easier to evaluate visually than one with the mask.
Nor would it be any easier to establish a profile within your scanning software than for one with the mask.

maybe the film that is used to print motion picture negs into positives?? I have no actual knowledge of such a product, but it probably exists, or did at some time. probably not ideal for in camera, general photography...

And you know, you are completely correct.
How did I miss that?
In my defense, I would point out:
a) I've seen numerous posts from people in the past who seemed to consider the orange mask as an impediment to scanning; and
b) I think that the inverted colours would be as much a challenge to deal with when printing black and white as the orange mask is.

Not interested in doing this, but Fix before Bleach?

Yes, but there's a good wash step missing between the two.

The first developer is B&W, the film is fixed and washed well then a rehalogenating bleach is used NOt the usual colour film bleach or bleach-fix, then re-exposure and when you develop in a colour developer you get the dye-coupled colour negative image, then you need to bleach-fix to remove the silver negative image and just leave the dye image.

where are you based? In Europe CN200 is still available at many internet sdhops. Sometimes it goes out of stock but comes back regularly

expiry date 2020. It is fresh stuff. Perhaps agfa produces just a batch when needed

This is however only 120 format, same with many other websites. You can find that still, however 135/35mm of that film cannot easily be found anymore.
Maybe 120 was simply bought less and therefore these are leftovers. I have a few rolls of 35mm and they also have expiration dates way in the future.

I thought it was crazy when I first read it, but then, thinking about it, it made sense. Ian's explanation makes it even clearer.

I wrote that post late in the night, as I was insomniac, and forgot some really important details. Thanks for correcting me, Ian.

Cheers,
Flavio
