Subject: Paper fibers attached to silver gelatin photographs

Paper fibers attached to silver gelatin photographs

Recently we became aware that part of the Korean/Japan negative
collection has paper fibres attached/embedded to either the silver
gelatin layer and/or the anti-halation layer. It seems the problem
occurred because contact prints were put on the storage envelopes
with a photo paste (possibly dextrin) which has leached through the
paper fibres subsequently attaching the paper to the gelatin.

Although the fibres can be removed mechanically with a scalpel under
a microscope we are looking for a simpler method, ie., a chemical
treatment that would allow the paper fibres to be wiped away without
major disturbance to the gelatin supercoat and/or the underlying
image formation.

Our conservation laboratory will investigate probable solutions to
this problem, but we wonder if there is a simple solution which has
been used with success without damaging the original negative
