Abstract
Polyurethane cationomers containing azoaromatic dyes and o,p-nitroarom atic photoactive groups, covalently or electrostatically incorporated, have been synthesized. The photobehavior of polymer solutions and fil ms was studied by electronic absorption spectra. It was found that a b leaching process occurs in these polymers by UV irradiation.
