The research on light induced aging of finishing techniques such as face mounted colour photographs aims at the question whether yellow and magenta dyes fade more rapidly within face mounted colour photographs. Furthermore an investigation into the chemical mechanisms of the degradation processes should provide insight into the potential problems associated with the face-mounting of print.
