3-Aryloxyanthra-6-isoxazolones gives good chemical and quantum yields of the photorearrangement products naphthophenoxazine-8,13-diones, identical with the thermal rearrangement products.The formation of a spiro intermediate was demonstrated.An intermediate particle which changes thermally into the final reaction product was detected.The structure of the intermediate particle was determined by study of the photochemical and subsequent thermal transformations of 3-(2,4,6-trimethylphenoxy)-5-hydroxyanthra-6-isoxazolone.Slow conversion at the nitrogen atom was detected in N-methyl-1,3-dimethylnaphtho phenoxazine-8,13-dione
