Definitions

  • Both the fast high contrast and slow low contrast emulsions were spectrally sensitized with 400 mg/Ag mol of anhydro-5,5-dichloro-9-ethyl-3,3′-bis(3-sulfopropyl)oxacarbocyanine hydroxide, followed by 300 mg/Ag mol of potassium iodide.
  • the slow low contrast emulsion was coated at a silver coverage of 1.6 g/m2 and a gelatin coverage of 3.3 g/m2.
  • the fast high contrast emulsion was coated at a silver coverage of 2.2 g/m2 and a gelatin coverage of 3.3 g/m2.
  • Protective gelatin layers (0.7 g/m2) were coated over the emulsion layers.
  • Emulsion SLC When coated as described above, but symmetrically, with Emulsion SLC coated on both sides of the support and Emulsion FHC omitted, using a Screen Y pair, Emulsion SLC exhibits a contrast of 1.7 at an overall density of 1.0. Similarly, when Emulsion FHC is coated symmetrically with Emulsion SLC omitted, Emulsion FHC exhibits a contrast of 2.9 at an overall density of 1.0. The speed difference in the two coatings at an overall density of 1.0 is 0.7 log E.
