Higher speed color photographic element and a method for high speed imaging

A method of imagewise exposing to at least one of green and red light a dye image forming photographic element comprised of

• a transparent film support and, coated on the support,
• at least one layer unit containing a silver halide emulsion containing chemically sensitized silver halide grains, adsorbed to the silver halide grains a spectral sensitizing dye having a peak absorption in the green or red region of the spectrum to which the photographic element is imagewise exposed, a dye-forming coupler and a dispersing medium,
• wherein
• exposure of at least one portion of the photographic element is limited to 1.33.times.10.sup.-3 lux-seconds and
• at least 50 percent of the projected area of the silver halide grains is accounted for by grains (a) containing greater than 50 mole percent chloride, based on silver, (b) having {100} major faces, (c) exhibiting a thickness of 0.2 .mu.m or less, (d) exhibiting a mean equivalent circular diameter in the range of from 3 to 6 .mu.m, and (e) including a core and a surrounding band containing up to 30 percent of the silver forming the grains and a higher level of iodide ions than the core,
• so that when the photographic element is developed for 3 minutes and 15 seconds at 38.degree. C. in a developer of the composition:
• ______________________________________ Potassium carbonate, anhydrous 34.30 g Potassium bicarbonate 2.32 g Sodium sulfite, anhydrous 0.38 g Sodium metalsulfite 2.78 g Potassium iodide 1.20 mg Sodium bromide 1.31 g Diethylenetriaminepentaacetic acid, 8.43 g Pentasodium salt (40% solution) Hydroxylamine sulfate 2.41 g Water to 1 Liter pH 10 ______________________________________
• and subsequently bleached and fixed, it exhibits a density above fog of at least 0.15 in the at least one portion of the photographic element receiving the exposure of 1.33.times.10.sup.-3 lux second.
