Abstract

1398828 Photographic silver halide emulsion containing a bispyrazolone coupler FUJI PHOTO FILM CO Ltd 11 July 1973 [11 July 1972] 33163/73 Heading G2C [Also in Division C2] A silver halide colour photographic emulsion contains at least one bis-3-ureido pyrazolone of the Formula I:- wherein R<SP>1</SP> is a substituted or unsubstituted alkyl, cycloalkyl, aralkyl, or aryl group, R<SP>2</SP> is an alkyl or a cycloalkyl group, or a substituted or unsubstituted aryl group, and R<SP>3</SP> is a substituted or unsubstituted alkyl, cycloalkyl, aralkyl or aryl group. This coupler may be used in combination with other couplers (see Ex 2 and 3).
