| titleOfInvention | Photographic element, compound, and process |
| abstract | Disclosed is a photographic element comprising a light-sensitive silver halide emulsion layer having associated therewith a phenolic "NB magenta coupler" having the formula:wherein:the term "NB magenta coupler" represents a coupler of formula (I) that forms a magenta dye with the developer 4-amino-3-methyl-N-ethyl-N-(2-methanesulfonamidoethyl) aniline sesquisulfate hydrate for which the maximum absorption of the dye upon spin coating is in the range of from 520 to 590 nm and the left bandwidth (LBW) or the right bandwidth (RBW) using spin-coating, is at least 5 nm less than that of the same dye in solution form;R1 is a heterocyclic, carbocyclic, or alkenyl group with substituents of sufficient electron withdrawing capacity to obtain a spin-coated dye as described in the preceding subparagraph that exhibits a maximum absorption in the range of 520-590 nm;Y is H or a coupling-off group;each Z* is an independently selected substituent group where p is independently 0 to 2;R2 is a heterocyclic or carbocyclic ring group, or an alkyl group;provided that when R2 is an alkyl group with an alpha-alkyl substituent, said alpha-alkyl substituent is unbranched; andprovided further that the combined sum of the aliphatic carbon atoms in R1, R2 and all Z* is at least 8. |
