Abstract:
The invention relates to a multilayer photographic element comprising a reflective support wherein the color record 1 adjacent to the support comprises at least one light sensitive layer and a non-light sensitive dye-forming interlayer; and wherein color record 2 above said color record 1 comprises at least one light sensitive layer and at least two non-light sensitive dye-forming interlayers and wherein color record 3 above said color record 2 comprises at least one light sensitive layer and a non-light sensitive dye-forming interlayer; and a top overcoat layer comprising gelatin and ultraviolet absorbing material; and wherein each interlayer is substantially scavenger free, and color records 1, 2, and 3 comprise silver halide grains comprising greater than 90% silver chloride, and wherein the reciprocity characteristics of the silver halide grains are such that for a separation exposure of 1 microsecond and 0.4 sec, at least one color record develops to a density of at least 2.0 within a log exposure range of 1.2 or less relative to the exposure point producing a density 0.04 above Dmin.
