A photochromic polymer film is prepared by the oxidation polymerization of a diarylethene. The photoreactive conformation is maintained. A pattern can be written on the film using visible light, and upon irradiation with IR light, a non‐destructive read‐out of the patterned image is carried out. The structural changes resulting from illumination are shown in the Scheme.
