Abstract

1,019,693. Photographic silver halide emulsions. FUJI SHASHIN FILM KABUSHIKI KAISHA. Feb, 28,1964 [March1 , 1963], No. 8544/64. Heading G2C. Photographic gelatino-silver halide emulsions contain a hydroxyethyl or hydroxypropyl ether of starch or of starch products obtained by treating starch with enzymes, acids, alkalis or oxidizing agents and/or by heating, either before or after etherification. Reference is made to the use of ethers of starch, starch hydrolyzed with hydrochloric acid, dextrin and gums. The starch products not only increase the covering power of the silver, but act also as sensitizers.
