摘要： A multicolor photographic element capable of forming a viewable reversal dye image is disclosed comprising a support and, coated on the support, a blue recording yellow dye image forming layer unit, a green recording magenta dye image forming layer unit, and a red recording cyan dye image forming layer unit, each of the layer units containing in at least one layer a silver halide emulsion having a grain halide content of from 0 to 5 mole percent chloride, from. 0.5 to 20 mole percent iodide, and from 80 to 99.5 mole percent bromide, based on total silver.The photographic element is characterized in that at least one of the silver halide emulsion layers is a tabular grain emulsion layer in which the coefficient of variation of the tabular grain emulsion is less than 15 percent, based on the total grain population of the emulsion, and the total grain population of the tabular emulsion consists essentially of tabular grains having a mean thickness of less than 0.3 .mu.m and a mean tabularity of greater than 25.

摘要： A multicolor photographic element capable of forming a viewable reversal dye image is disclosed comprising a support and, coated on the support, a blue recording yellow dye image forming layer unit, a green recording magenta dye image forming layer unit, and a red recording cyan dye image forming layer unit, each of the dye image forming layer units containing at least one silver halide emulsion layer comprised of a vehicle and silver halide grains having (1) a halide content of from 0 to 5 mole percent chloride, from 0.1 to 20 mole percent iodide, and from 80 to 99.9 mole percent bromide, based on total silver. At least one of the silver halide emulsion layers in one of the layer units positioned to receive exposing radiation prior to at least one of the green or red recording layer units is a tabular grain emulsion layer in which a polyalkylene oxide block copolymer is present selected to allow the preparation of tabular grains having a mean thickness of less than 0.3 .mu.m and a mean tabularity of greater than 25, accounting for greater than 97 percent of the total projected area of grains having an equivalent circular diameter of at least 0.2 .mu.m.

摘要： A photographic element comprises a support having thereon a layer containing a hydrophilic vehicle having dispersed therein a particulate polymeric material encapsulated with a chelating or already chelated polymer, said element, when the polymer is not already chelated, comprising a source of metal ions. The elements are useful in diffusion transfer processes, and particularly useful with chelating acid dyes or dye-forming materials to provide a metallized dye image.
