Paper Abstract

Dichromated polyacrylic acid (DCPAA) has been used as real time holographic recording material. We report here the photochemical behavior of DCPAA when irradiated under conditions similar to those used for hologram recording. A photoredox process was observed whose efficiency depends on the presence of an electron donor, dimethylformamide (DMF). By ESR spectroscopy upon irradiation four different species were detected and identified: (1) chromium (V) of thermal origin (in the dark); (2) chromium (V) of photochemical origin; (3) an organic macroradical; (4) chromium (III). DMF appeared to possess a strong influence on the formation of these species.
