New Silver Chloride Azo type paper

[Photo Engineer]

I have been able to perfect (well, as far as I can go anyhow) an Azo type paper that is green (ortho) sensitive. It looks like regular Azo the way I make it, but is at least a stop faster.

Now, this might be interesting with negatives processed in staining developers, but IDK. I'm putting this up here for a response.

What do you think?

Well, my first response is: Gimme!

being that it is a whole stop faster is also very nifty. There are a lot of folks who miss AZO, I know I am one of them.. I still have 30 sheets or so of grade 3 that I haven't been able to make myself use.

Anyways, I think it sounds great PE !

Sounds interesting to me. What ballpark exposure times do you get? Is it complicated to make?

I'd be very interested in it if you need some testing.

Well, that's great news... but, are there plans to produce and market this emulsion or would this be a home brew alternative?

Could you ask Ilford to do a run of it :-)

This is a trial baloon for something that has never been made before AFAIK. It can be made at just about original Azo speed in grade 2 or 1 - 2 stops faster in grade 3. I'm still working on this.

Sounds great. A stop faster, green sensitive, should be usable as an enlarging paper, particularly with cold light (and even more particularly with the older greenish tubes).

How are the keeping qualities, if you've tested that yet?

I'm not a LF contact printer yet, but this is extremely cool.
