Inquisition on the Photochemical Degradation of Silver Gelatin Photograph Print-Out

Abstract

This paper shows the experimental and analytical studies of gelatin behavior at photographic prints during the exposition to ultraviolet radiation. The test material used is black-and-white photographic paper. Different properties and characteristics of the prints have then been measured and compared before and after the irradiation. SEM used to study the surface topology of the gelatin. FTIR-ATR XRF analysis used to modify characteristic of the surfaces. Mechanical performance used to study. Color change was studied. The obtained results indicate a strong effect of the UV radiation in the color characteristics of the silver image, a certain change in the mechanical properties of the supporting paper and only slight consequences on the chemical properties of gelatin, which may probably increase with time.
