It all depends on the adhesive used. Also certain plasticizers will 
turn the papers yellow. I've only seen this with German Etching when 
I get down to the end of the roll where it is taped. And that was on 
a partial roll that I found in storage, it was about 5 years old at 
the time, and was only yellow where the adhesive was attached to the 
paper.
