Motion picture film materials containing magnetic recording stripes

A multilayer motion picture film material comprising a support, at least one light-sensitive emulsion layer on one side of such support and, at the opposite side of said support, an antihalation layer capable of being removed from said support in the presence of an alkaline solution, and also comprising, on said antihalation layer, at least one stripe formed by the application thereto of a coating composition containing magnetizable material dispersed in an alkali-insoluble binder, said composition containing a cross-linking agent for the alkali-soluble binder of said antihalation layer, characterized in that as a said cross-linking agent, at least one bis- or polyepoxide is used in combination with at least one sulphoxide and/or formamide, said bis- or polyepoxide corresponding to one of the formulae:

• ##STR13## and ##STR14## wherein R represents an alkyl group of 1 to 6 carbon atoms, a benzyl group, or a group of the formula ##STR15## and each of R' and R" represents a methyl group, or a ##STR16## or R' and R" together represent a --CH.sub.2 --CH.sub. 2 -- group.
