The soundtrack images which overlie at least a portion of the visible image area of the film are digitally coded on the film using an electrostatic imaging system to imprint a fluorescent toner. The toner may comprise a fluorescent polymer having covalently bonded 3-phenyl-7-(amido or imido)-coumarin or certain substituted stilbene or N-alkyl-4-aminonaphalimides.
