ABSTRACT:
The adherence of a magnetic sound strip to the surface of an anti-halation layer of a multi-layer motion picture film including at least one light-sensitive emulsion layer is enhanced by using as the alkali-soluble binder of the anti-halation layer a polymer containing free carboxyl groups and including in the coating composition of the magnetic strip an organic compound which contains at least two reactive halogen atoms reactive with the polymer carboxyl groups.
