Photochromic compounds have the general formula
in which R, represents an alkyl group having 1 to 20 carbon atoms, each of R2. R3. R4 and R5 independently represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, a halogen atom, a mitro, a cyano group or a dimethylamino group, and each of R6, R7 and R8 independently represents a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, or a halogen atom. A photosensitive composition may comprise 3 to 50 wt% of such a compound and 97 to 50 wt% of a film-forming polymer. A photosensitive material may comprise a film of such a composition.
