See the patent, it has some clues about amounts. I can't be sure this is
what Kodak uses in Microdol-X but it looks very possible.
There are two good sources of U.S. patents. One is the U.S. Patent and
Trade-Mark Office at:
http://www.uspto.gov the other is the new Google patents search. Go to
Google and type Google patents in, it will list the web site first. The
Google site has the advantage of allowing text searches for any patent where
the patent office site allows them only for patents issued after 1975. I
found this one by searching for Richard W. Henn, one of Kodak's top
researchers.
