    摘要: A color photographic element comprising a support and first and second silver halide emulsion layers sensitized to first and second regions of the electromagnetic spectrum respectively and each containing a dye forming coupler, wherein the second emulsion layer is to a limited extent also sensitized to the first region of the spectrum. The element exhibits extended exposure latitude.

    摘要: Photographic compounds capable of releasing a photographically useful group (PUG) by means of an intramolecular nucleophilic displacement provide increased image acutance when a coupling-off group in the coupling position of the compound is a group of the formula:
    wherein PUG is a photographically useful group; Q is N or C-R where R is hydrogen or a substituent that does not adversely affect imaging; and Z represents atoms completing a non-aromatic, heterocyclic ring system. The photographic compounds are useful in photographic materials and processes and enable increased acutance of developed images.

    摘要: A solid particle dispersion of a dye having the formula:
    R₁ and R₂ are each independently substituted or unsubstituted alkyl or aryl, or together represent the atoms necessary to complete a substituted or unsubstituted 5- or 6-membered ring,
    R₃ and R₄ each independently represents H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, CO₂H, or NHSO₂R₆,
    R₅ is H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, substituted or unsubstituted carboxylate, substituted or unsubstituted amido, or substituted or unsubstituted acyl,
    R₆ and R₇ are each independently substituted or unsubstituted alkyl or substituted or unsubsti­tuted aryl,
    R₈ is substituted or unsubstituted alkyl, or together with R₉ forms a double bond,
    R₉ is H or together with R₈ forms a double bond, and
    n is 1 or 2,
    with the proviso that at least one of the aryl rings of the dye molecule has at least one substituent that is CO₂H or NHSO₂R₆, are useful as filter dyes in photographic elements.
