ABSTRACT:
The present invention relates to a method of forming a dye image which involves processing a light-sensitive silver halide photographic image, after its imagewise exposure, in the presence of a novel yellow coupler as depicted in the formula below and an aromatic primary amine color developing agent ##STR1## wherein R.sub.1 represents cyano, alkyl carbonyl, phenylalkyl carbonyl, phenoxy alkyl carbonyl, phenylthio alkyl carbonyl, arylcarbonyl, alkyl phenyl carbonyl, alkoxy phenyl carbonyl, R.sub.2, R.sub.3, R.sub.4, R.sub.5 independently are hydrogen, halogen, alkyl, alkoxy, aryloxy, alkylacyloxy, arylacyloxy, acylamino, N-alkyl carbamoyl, N-phenylcarbamoyl, alkylsulfonamido, arylsulfonamido, N-alkyl sulfamoyl, N-phenylsulfamoyl, or imido, R.sub.6 represents cycloalkyl, alkenyl, naphthyl, thienyl, benzothienyl, furyl, or pyranyl, or a group of the formula (II): ##STR2## wherein R.sub.7, R.sub.9 and R.sub.11 are each hydrogen or alkyl, the sum of the carbon atoms in R.sub.7, R.sub.9 and R.sub.11 being 5 to 20, R.sub.8 and R.sub.10 are hydrogen, and Y represents non-metal atoms required for forming 2,5-dioxo-imidazolidine, 2-3,5-trioxo-imidazolidine, 2,5-dioxo-triazolidine, 2,4-oxazolidinedione, 2,4-thiazolidinedione, 2(1H)-pyridone, 2(1H)-pyrazone, 5(1H)-imidazolone, 5(1H)-triazolone, 2(1H)-pyrimidone, 2-pyrazolone (5), 2-isothiazolone(5), 2(1H)-quinaoxazolone, 4(3H)-pyrimidone, 2-benzoxazolone, 4-isooxazolone(5), 3-fluorone(2), 4-imidazolone(2), 3-pyrazolone, 2-tetrazolone(5), 3-tetrazolone(5), and derivatives thereof.
