Like a quasi-diffusion transfer .
There are all sorts of reaction products depending on the emulsion and developer constituents, but bromides are fairly typical. Iodide can be there too.
PE: How do you plan on testing your HA dev along the way? What methods will you use? I'm assuming for example you don't have a microdensitometer handy - unless you've been holding out on us!! Also if there is any way I can help you with this project let me know.
By the way, following my mention of the reference to a patent of yours in Haist I wanted to provide more detail for anyone interested. It is on page 467 of volume II in the Color Photographic Systems chapter, The Nature of Color Development section, Color Developing Agents subsection. "In a 1972 patent Richard L. Bent and Rowland G. Mowrey claimed certain p-phenylenediamine derivatives produced image dyes of superior stability to prolonged exposure to light, heat, or humidity. ...". The reference indicates "Color Photographic Processes," U.S. Pat. 3,656,950 (1972).
I quick question for everyone/anyone regarding copyright etc. If I reference Richard Henry clearly am I allowed to scan and post say a table of results from his book in this thread? Sorry if that is a dumb question but I have no idea what we're allowed and not allowed to do and we all remember that recent insane thread (now deleted) with the guy who was trying to make a formula book.
