Abstract

1,073,625. Gelatine silver halide emulsions. FOTOCHEMISCHE WERKE BERLIN VEB. June 12, 1964, No. 24528/64. Heading G2C. Gelatine silver-halide emulsions contain 5-50% by weight, based on the gelatine, of a carboxyalkylated dextran and/or a carbalkoxylated starch, preferably having a molecular weight of 5,000- 200,000, to increase the covering power of the emulsion.
