Abstract

1,74,303. Photographic sliver halide colour materials. E. I. DU PONT DE NEMOURS & CO. Aug. 14, 1964 [Aug. 14, 1963; Aug. 7, 1964], No. 33303/64. Heading G2C. A photographic multilayer colour film comprises a film support carrying a plurality of photosensitive gelatino silver halide emulsion layers each containing a colour-former, at least one of said colour-formers having colour-forming nuclei attached to structural units of a polymeric chain, there being present in at least one of the emulsion layers or in another gelatine layer (a) 0À01 - 2À5% (based on the weight of gelatine in the layer) of a compound forming bi-sulphite ions or a complex of such a compound with an organic carbonyl compound and (b) a photographic silver halide developing agent. The bi-sulphite ion and developer improve the latent image stability. Bi-sulphiteion-forming compounds and complexes are sodium or potassium sulphite, bi-sulphite or metabisulphite, an alkaline earth metal bi-sulphite, and complexes thereof with acetone, methyl ethyl ketone, formaldehyde and acetaldehyde. Developing agents specified are hydroquinone, catechol, pyrogallol, 2:5-dihydroxy-diphenyl, metol, N- ethyl-p-aminophenol, p-diethylamino-aniline, p-dimethylaminoaniline, p-aminoaniline, 2- amino-5-diethylamino-toluene, 4-amino-N-(# - methanesulphonamidoethyl)-m-toluidine and 4- amino-3-methyl-N-ethyl-N-(#-hydroxyethyl) aniline. Polymeric colour-formers described are those of Specifications 995, 364, 995, 363 and 967, 504.
