  • Silver halide color photographic light-sensitive material
    Patent number: 5496692
    Abstract: Silver halide color photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer containing a) an alkoxybenzoylacetanilide DIR coupler having bonded to the coupling active position a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoylacetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position to provide, upon exposure and development, color images of improved image sensitivity.
    Type: Grant
    Filed: November 14, 1994
    Date of Patent: March 5, 1996
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Massimo Bertoldi, Vinicio Busatto
  • Silver halide color photographic light-sensitive material
    Patent number: 5332656
    Abstract: Silver halide color photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer containing a) a diacylaminomethylene yellow dye forming coupler having bonded to the coupling active position a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoyl acetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position.
    Type: Grant
    Filed: March 22, 1993
    Date of Patent: July 26, 1994
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Massimo Bertoldi, Vinicio Busatto
  • Method for obtaining a color contrast photographic image, photographic element and development composition suitable for the realization of said method
    Patent number: 3941599
    Abstract: Color contrast photographic images may be produced in a photographic element comprising:1. a base2. at least one layer of a silver halide photographic emulsion dispersed in a hydrophilic colloidal binder and reactively associated with at least one color coupler, and3. at least one hydrophilic colloidal binder receptive layer containing dispersed silver condensation nuclei for the formation of colored colloidal silver, reactively associated with said emulsion layer, said nuclei and coupler selected to give rise to substantially differing colorsBy developing said photographic element in the presence of a p-phenylene diamine developer and carrying agent for silver halide.

    Filed: June 20, 1975
    Date of Patent: March 2, 1976
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Vinicio Busatto, Luigi Franchi
