   You may find some information on the archived web pages 
from Ryuji Suzuki's web site at Silvergrain org. Try Google. 
The site was destroyed but much of the information remains 
in variious archive sites.
   Commercial silver-gelatin printing paper is sized in 
various ways. The usual method is to coat the paper with a 
substrate of hard gelatin with the reflective material in 
suspension. However, there is more to it than this. Kodak 
and others used to make paper which could be folded without 
breaking. This had some other type of sizing, I don't know 
how this was done. In any case I am under the impression 
from what I've read that your problem is not unusual. Ryuji 
does sometimes read this list and may respond. I know he has 
experimented, with some success, with making his own 
emulsions and coating them.
