Photographic element having a magnetic recording stripe overlying an antistatic layer

A photographic element comprising a support, an antistatic layer on said support comprising a phosphate ester antistatic agent, and a magnetic recording stripe overlying said antistatic layer, said magnetic recording stripe comprising magnetic particles dispersed in a polymeric binder and containing a carboxylic acid salt of a polyvalent metal in an amount sufficient to enhance the adhesion of said stripe to said element.

A photographic element comprising a support, an antistatic layer on said support comprising a phosphate ester antistatic agent, and a magnetic recording region overlying said antistatic layer, said magnetic recording region comprising magnetic particles dispersed in a polymeric binder and containing a carboxylic acid salt of a polyvalent metal in an amount sufficient to enhance the adhesion of said magnetic recording region to said element.

A photographic element comprising a support having on one side thereof at least one radiation-sensitive layer and on the opposite side an antistatic layer comprising a phosphate ester antistatic agent, said element additionally comprising a magnetic recording region overlying said antistatic layer, said magnetic recording region comprising magnetic particles dispersed in a polymeric binder and containing a carboxylic acid salt of a polyvalent metal in an amount sufficient to enhance the adhesion of said magnetic recording region to said element.

A photographic element comprising a support having on one side thereof at least one radiation-sensitive layer and on the opposite side an antistatic layer comprising a phosphate ester antistatic agent, said element additionally comprising a magnetic recording stripe overlying said antistatic layer, said magnetic recording stripe having been formed by depositing on said antistatic layer a stripe of a composition comprising a suspension of finely-divided magnetic particles in a liquid medium and drying said stripe, said liquid medium comprising a polymeric binder and a carboxylic acid salt of a polyvalent metal, said salt being present in said striping composition in an amount sufficient to enhance the adhesion of said stripe to said element.

A photographic motion picture film comprising a cellulose triacetate support having on one side thereof at least one gelatin silver halide emulsion layer and on the opposite side an antistatic layer comprising potassium mono-cetyl phosphate, said film additionally comprising a magnetic recording stripe overlying said antistatic layer, said magnetic recording stripe having been formed by depositing on said antistatic layer a stripe of a composition comprising a suspension of finely-divided magnetic particles in a liquid medium, said liquid medium comprising cellulose nitrate and chromium octoate, said chromium octoate being present in said striping composition in an amount sufficient to enhance the adhesion of said stripe to said film.

In a method of forming a magnetic recording stripe on a photographic element, said element comprising a support having on one side thereof at least one radiation-sensitive layer and on the opposite side an antistatic layer comprising a phosphate ester antistatic agent, which method comprises applying over said antistatic layer a stripe of a magnetic striping composition comprising a suspension of finely-divided magnetic particles in a solution of a polymeric binder, the improvement wherein said striping composition additionally contains a carboxylic acid salt of a polyvalent metal in a concentration sufficient to enhance the adhesion of said stripe to said element.
