Abstract
Dichromated polyacrylic acid (DCPAA) and dichromated polyvinylalcohol (DCPVA) have been investigated with a double approach: photochemical behavior and holographic results. The study focused on two particular systems: the effect of the addition of nitrilotriacetic acid (NTA) or dimethylformamide to the photosensitive material. From the photochemical mechanism it was possible to assess that the complexing ability of both compounds plays a major role in the optimization of the holographic properties of the material. On the contrary, the presence of an electron donor like NTA in DCPAA is less favorable. A close correlation seems to be present between the photochemical behavior and the results obtained in holography.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
