Abstract
Photographic elements are provided with a magnetic stripe that is useful for sound recording by applying a magnetic striping composition, containing finely-divided magnetic particles and an acrylated epoxy resin, over the anti-halation layer of the element. The striping composition penetrates the anti-halation layer to contact the support and is cured to an alkali-insoluble cross-linked stripe which is composite with the anti-halation layer and strongly bonded to the support so as to resist removal by alkaline photographic processing solutions.
