Abstract

1432067 Preparation of photographic film FUJI PHOTO FILM CO LTD 18 May 1973 [19 May 1972] 23924/73 Heading B2E [Also in Division G2] A method of making a cinematographic film having a magnetic recording layer comprises treating the antihalation layer of a film having a cellulose derivative support with a solution containing at least one compound having at least two aziridine rings and subsequently applying a magnetic dispersion to the antihalation layer or alternatively applying to the antihalation layer a magnetic dispersion containing at least one aziridine compound as defined above. The support is preferably cellulose triacetate, the antihalation layer preferably comprises a hexahydrophthalate or tetrahydrophthalate of hydroxyalkyl alkyl cellulose and the compound(s) contain two to four aziridine rings.
