Help?!
Using a 8x10 BPF200 neg formerly contact printed in Ziatype process numerous times I intentionally put way-to-much excess moisture in paper. (Please don't ask why).
Resulted was - no surprise - emulsion remnants on neg emulsion face (never use mylar interface, have never needed to).
Several weeks later neg was subjected to rinsing in water plus a little photoflo. Zia emulsion remnants did not come off (as a suspected they wouldn't) BUT A CLEAR LAYER ON THE ANTIHALATION BACKSIDE STARTED TO WRINKLE AND CONTRACT. Took twenty minutes to completely rub-rinse the layer off by thumb.
Neg has now dried and appears same as before (complete with the self-inflicted emulsion-side stains).
QUESTION IS WHAT WAS THIS LAYER?? Can't find anything on this type event in any reference. Any thoughts?
