摘要:
Disclosed is a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith a yellow dye-forming coupler having formula I :
wherein
each A is independently a divalent group selected from the divalent groups consisting of aryl and -C(R 1 )(R 2 )-, in which each R 1 and R 2 is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryloxy, heterocyclic, and aryl groups, and one A can be joined to form a ring with another A or with R 3 , and m is from 2 to 6;
R 3 is selected from the group consisting of hydrogen, alkyl, heterocyclic, and aryl groups, provided that R 3 may form a ring with A or is a group joined to R 4 to form a heterocyclic five- or six-membered ring;
R 4 is selected from the group consisting of aryl, heterocyclic, and alkyl groups and may form a heterocyclic ring bonded to R 3 ;
Y is selected from the group consisting of-SO 2 -, -C(=O)-, -C(=O)NR 9 R 10 -, -C(=O)O-, and -P(=O)(OR 9 )(OR 10 -) where R 9 and R 10 are independently H or an alkyl or aryl group; and
the remaining substituents are as described in the summary of the invention.
