I picked up a copy before the holiday, and skimmed the section that CMB referenced. It's a bit over my head, chemistry-wise. I'll have to go through it again to see if I can glean anything useful from it.

I'm hoping Charles or someone else following this thread can answer the following question for me:

In looking through one chemical supplier's catalog, I came across a number of very similarly named compounds. It's not clear to me how they differ from one another as a practical matter, what benefits/detriments the different variations have, nor how to determine which would be appropriate for this endeavor. Example:

4-DIAZODIPHENYLAMINE/FORMALDEHYDE CONDENSATE HYDROGEN SULFATE
4-DIAZODIPHENYLAMINE/FORMALDEHYDE CONDENSATE HEXAFLUOROPHOSPHATE
4-DIAZODIPHENYLAMINE SULFATE
4-DIAZODIPHENYLAMINE/FORMALDEHYDE CONDENSATE HYDROGEN SULFATE ZINC CHLORIDE COMPLEX

The first one has the same CAS# (41432-19-3) as a widely-used screen emulsion sensitizer.
