Abstract
A process for forming an optical sound track which comprises applying a nitrogen containing heterocyclic compound in which at least one of the nitrogen atoms is connected to a group having 6 or more carbon atoms to form a quaternary salt to a sound track area of a multilayer color photographic material, after color development but prior to a bleaching step, whereby an optical sound track can be easily prepared on a conventional multilayer color photographic material.
