Bill;

After looking through my old emulsion work, I find one interesting thing. Most polymers useful for "peptizing" or making an emulsion were not best for coating it. You had to mix two polymers. One was used for making and a second polymer was added for coating. I have several Defensive Publications and Research Disclosures on this. The rest is confidential.

We also attached couplers to polymers to make color coatings.

I cannot help you with the RDs and DPs, as they cost $$ to read and copy.

In any case, useful perhaps to you.
