Bill,

Thanks for the link.

HP clearly found a characteristic in the latex that I thought should exist in something, but I never stumbled onto the latex.  To quote the HP patent application, "[I]t has been found unexpectedly that using a low conductivity latex dispersion increases particle stability of latex containing inkjet ink compositions."

I suspect that could be an important part of their "electro-steric" dispersion system.  

I see they also found the Tergitol line of surfactants.  

I must say, I've always been impressed with the HP R&D.  They have the $ and staff to do it right, not that Canon and Epson (I suspect via Fuji and others for chemistry) do not.
