<p>A multilayer motion picture film material comprises a support, at least one light-sensitive emulsion layer on one side of the support, and at the opposite side of the support an antihalation layer capable of being removed from the support in the presence of an alkaline solution. On this antihalation layer at least one stripe is applied from a coating composition containing magnetizable material dispersed in an alkali-insoluble binder and also containing a cross-linking agent for the alkali-soluble binder of the antihalation layer. As cross-linking agent is used at least one bis- or polyepoxide in combination with at least one sulphoxide and/or with formamide, the bis- or polyepoxide corresponding to one of the formulae : and wherein R represents an alkyl group of 1 to 6 carbon atoms, a benzyl group or a group of the formula and each of R' and X" represents a methyl group, or a group or R' and R" together represent a -CH2-CH2- group.</p> |
