Ryuji this may help http://spitbite.org/carbon/papers/TheChibaSystem.pdf Chris At 22:22 15/06/2008, you wrote: I always meant to post this note to this list but I think I forgot for a year. An article entitled "Chiba Type --- A non-toxic alternative to gum dichromate" by Halvor Bjørngård and Hiroyuki Kobayashi was published in Journal of the Society of Photographic Science and Technology of Japan, volume 70, pages 102-112. I think this is a part of his thesis work at Chiba University. Abstract is in English and Japanese, but the text is in English. I only have a bound journal and they don't post electronic version so I don't have anything I can paste here (besides the copyright issue), but if anyone is seriously interested, please let me know privately. -- Ryuji Suzuki "The truth that I am seeking is in your missing file."
