Abstract

1,274,436. Optically sensitized emulsions. FILMFABRIK WOLFEN VEB. June 9, 1970, No.27831/70. Heading G2C. [Also in Division C4] Silver halide emulsions are sensitized with dyes of the formula: - where R 1 and R 4 are H, CI, CN, COOH, or COOAlkyl; R 2 , R 3 , R 5 and R 6 are alkyl with at least 16C, one of said alkyl groups containing at least 3 carbon atoms and another of said groups containing at least 6 carbon atoms and X is an anion.
