The photochemical reaction of dichromated gelatin was studied by laser photoa-coustic spectroscopy. Results show that the solid-state reaction of the dichromate with gelatin obeys Watanabe-Westheimer reaction scheme. The photosensitivity of dichromated gelatin is dependent on pH and concentration of dichromate solution.
