MAGNETIC DISPERSION ABSTRACT A dispersion consisting essentially of magnetic particles, a dialkylester of phthalic acid which functions as a dispersing medium, and optionally, a dispersing agent is particularly useful as a precursor to a composition suitable for casting onto a cellulose acid ester support film to form a transparent magnetic recording layer for use in photographic films. The dispersion provides magnetic recording layers exhibiting fewer particle agglomerations and reduced light scattering and photographic prints prepared from films containing such magnetic layers exhibit virtually no increase in graininess attributable to the magnetic recording layer.
