The Keeping Pace newsletters can be found by googling "Making Enlarged Separation Negatives for the Ultra Stable Process" the first 2 links.
google "http://www.daviddoubley.com/Documents/KeepingPaceNewsletters/" for lots of them. They dont seem to be accesable directly from his site.
Seems most all Kiwo sensitisers contain formaldhyde but the % varies. http://www.snugz.com/Compliance/Ink/...itizerMSDS.pdf
Seems Ulano 925WR sensitiser contains formaldehyde. Unshure about Ulano RLX emulsion sensitiser but it costs $200 for a gallon of the stuff and I am not going to risk $200.
After reading the post on dye transfer group I have decided to try the sensitiser that comes with Kiwo 225WR as it is available in small quantities locally.
Printing without Dichromate would be good for my health and the environment. Diazo is much easier to get than Dichromate. Also presensitised tissue would speed up printing dramatically, the disadvantage being in controlling contrast but with digital negatives that is not a problem.
