Abstract

968,883. Photographic materials. GEVAERT PHOTO-PRODUCTEN N.V. May 4, 1961 [May 14, 1960], No. 16183/61. Heading G2C. Photographic gelatinous compositions are preserved from decomposition by a process comprising incorporating into the compositions 0.1 1 to 1% based on the weight of dry gelatin of at least one single or mixed salts of cerium, erbium, lanthanum, neodymium, praseodymium, samarium, scandium and/or yttrium. The compositions are preferably photographic gelatino silver halide emulsions and the additive may be added to the solution before coating or by immersing the material after coating in a solution of the appropriate salt or salts.
