Photographic element having a transparent magnetic recording layer

摘要

A photographic element comprising a support having provided thereon a light-sensitive layer and a transparent magnetic recording layer, the magnetic recording layer comprising a transparent polymeric binder, ferro-magnetic particles and reinforcing filler particles, the magnetic particles having a surface area greater than 30 m2/gm and a coverage of from about 1x10-11 mg/ mu m3 to about 1x10-10 mg/ mu m3, the filler particles having a median diameter less than 0.15 mu m, a Mohs hardness of at least 6 and being present in the transparent magnetic layer in an amount of about 20% to about 300% by weight based on the weight of the polymeric binder present.
