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.
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.
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?
