The photodegradation of 6'-indolino-1-isobutyl-3,3-dimethylspiro[indoline-2,3'-[3H]naphtho[2,1-b][1,4]oxazine] (1) following exposure to polychromatic light, was investigated in fluid solution (toluene, T) and in a solid matrix (polyurethane, PU). The photoproducts formed under irradiation were identified using HPLC and GC/MS. These included, beside the expected degradation derivatives, some new photoproducts derived from a secondary degradation pathway.
