My only thought on that would be that if there were no exposed chemicals to
react with there would be nothing to see in the interframe or edge
areas. Only a guess though, I really am not current on what the process is
for color. Seems I stopped with silver halides. :-)
My reason for thinking chemical contamination, is I have seen negs that
looked that way after being contaminated, or not fixed properly. When I
have experienced overheating problems, it has taken out the entire roll.
