For the photographers needing make copy negatives, I don't know how well this would work, but you might try the DR5 lab. They can make positives out of a wide variety of B/W films. I have not tried it for copy negatives, but I have used them for B/W slides, and I was blown away by the results. http://www.dr5.com/main.html(posted 8223 days ago)On a different note:
Boycotting Kodak won't acomplish much of anything, especially if you were not using their product much in the first place. If your film is on the chopping block, then contact Kodak. If you are that passionate about convincing Kodak to keep a product, then pursuing something along the lines of those two people who are trying to save Azo paper might be in order, although it's no guaruntee that it would work.
Granted, Kodak does some things that just leave me scratching my head, such as marketing 5x7 (13x18cm) E100VS to the European market, while at the same time declining requests to ship a few boxes to dealers here in the states. I thought the goal was to move as much product as possible. But in spite of this, I like some of their products (E100VS instead of Velvia, TXT, PX, and TP) and I'm not going to boycott.
I still have confidence that consumers needs will be met by someone, even if it isn't always Kodak. Some examples include: the discontinuation of Infrared Sheet Film. I was not happy about that one, but Maco has one available in 4x5 now, painfully slow film though. Super XX Gone!, enter Berger 200. Kodachrome 25 gone, Fuji provia 100F is here with faster speed, finer grain and lower price tag (doesn't have the 150 year archival life, but I don't care if my slides outlive me and my kids)
If there is a demand for a product, someone will meet that demand, for a price.
