  • Direct view photographic element containing a particular green record
    Patent number: 6558886
    Abstract: Disclosed is a silver halide direct view multicolor photographic element comprising a green record containing a green light sensitized silver halide emulsion and comprising either (a) a magenta dye-forming coupler and a cyan dye-forming coupler in an amount of at least 0.1 mole % of the couplers present in the green record, or (b) a green record having a coupler or couplers sufficient to provide upon development a Status A red density greater than 0.23 as measured using a green light separation exposure at a Status A green density of 1.0.
    Type: Grant

  • Direct view photographic element containing a particular red record
    Patent number: 6555304
    Abstract: Disclosed is a silver halide direct view multicolor photographic element comprising a red record containing (1) a red light sensitized silver halide emulsion, (2) a cyan dye-forming NB first coupler, and (3) a second coupler selected from (a) a magenta dye forming coupler in an amount of 2-30 mole % of the total coupler in the red record and (b) a cyan dye-forming coupler having a greater absorption in the green spectra than the first coupler in an amount sufficient to provide a Status A green density in the range of 0.27 to 0.40 using a red light separation exposure at a Status A red density of 1.0. Such an element exhibits improved flesh tone reproduction and good dye dark stability.
