Abstract: A method is disclosed of obtaining from an imagewise exposed photographic element separate records of the imagewise exposure to each of the blue, green and red portions of the spectrum comprising photographically processing an imagewise exposed photographic element comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units that produce images of the same hue upon processing (e.g., lacking an incorporated dye-forming coupler). A first interlayer overlies the emulsion layer unit nearest the support for transmitting to it imagewise exposing radiation this emulsion layer unit is intended to record and for absorbing after photographic processing scanning radiation within at least one wavelength region.

Abstract: Liquid petroleum sulfonates are useful alone or in combination with less lipophilic anionic surfactants in the preparation of dispersions of water-insoluble photographic addenda, such as couplers and ultraviolet absorbers, in hydrophilic colloid compositions. Such dispersions are useful in photographic elements. Crystallization of the addenda is inhibited and, for some addenda, other advantages are obtained.
