PE, I'd be very interested in the list of dye bleach candidate chemicals. From what I've read, if I can make the bleach myself (and I'm pretty sure I can if at least one of the chemicals is obtainable -- nothing in that bleach is likely to be any more hazardous than the dichromate used in C-41 bleach, which people use for lots of things pretty routinely and safely), I can cut the cost of processing the Ilfochrome enough to be worth obtaining and cutting the paper or display film. It'd be nice to be able to get it precut to 9x12 cm film size, of course, to fit my sheaths...
