Abstract

478,357. Photographic films. KODAK, Ltd. June 17, 1936, No. 16912. Convention date, June 22, 1935. Addition to 470,565. [Class 98 (ii)] A photographic film comprises an organic cellulose derivative base and a gelatine emulsion carried by a gelatine substratum, to which good adherence of the emulsion and high flexibility are imparted by the application to the base of a very thin substratum, of a hydrophobic alkyd resin produced by reaction between one or more polybasic acids and one or more polyhydric alcohols or of a hydrophobic resin formed by reaction of formaldehyde or a polymer thereof with an aryl sulphonamide or an alkyl N-substituted aryl sulphonamide, to which very thin substratum the gelatine substratum is directly adherent. The resins may be produced by reaction between (a) glycerol and phthalic acid or its anhydride, (b) a polybasic organic acid, an alcohol having three or more hydroxyl groups in the molecule, a dihydric alcohol and a dibasic aliphatic acid, and (c) formaldehyde or a polymer thereof with ethyl p-toluenesulphonamide. The base may be of cellulose acetate or acetate-propionate. Suitable solutions for preparing the substrata are described. Specifications 349,956, [Group IV], and 470,565 are referred to.
