Abstract

Magnetic recording strips are applied to a cine film composed of (I) a support, (II) a light sensitive emulsion layer, and (III) an anti-halation layer on the other side of (I), and detachable from (I) in the presence of an alkaline soln., from a casting mixt. consisting of a dispersion of a magnetisable material and a carbodiimide crosslinker e.g. N,N'-di-isopropyl-carbodiimide, in an alkali insoluble binder. The carbodiimide is a very efficient crosslinker.
