ABSTRACT:
A photocoductive film comprising at least one photosensitive material dispersed in a resinous binder is supersensitized and the dark decay rate thereof reduced by adding an effective amount of an organic acid having at least one carboxyl functional group and at least one hydroxyl functional group to the coating mixture from which the film is formed. The organic acid is an independent component of the coating mixture and is substantially not copolymerized with the binder resin.
