Abstract
There is disclosed a silver halide color photographic material having at least one silver halide emulsion layer on a base, which comprises in the silver halide emulsion layer a magenta coupler, an image-dye stabilizer, and a high-boiling organic solvent of which the weight ratio to the coupler is 3.0 or over. The disclosure as described provides a color photographic material being excellent in color reproduction and having improved light-fastness of magenta color image with good balance from high density part to low density part.
Claims22
A silver halide color photographic material having at least one silver halide emulsion layer on a base, which comprises, in said silver halide emulsion layer, at least one magenta coupler represented by the following formula (I):
- ##STR70## wherein Za and Zb each represent ##STR71## R.sub.1 and R.sub.2 each represent a hydrogen atom or a substituent, X represents a hydrogen atom or a group or an atom capable of being released upon the coupling reaction with the oxidized product of an aromatic primary amine developing-agent, when Za and Zb together form a carbon-carbon double bond, Za and Zb may be part of the aromatic ring, and the compound may form a dimer or higher polymer through R.sub.1, R.sub.2, or X,
- at least one compound represented by the following formula (II):
- ##STR72## wherein R.sub.3 and R.sub.4 are each a methyl group, R.sub.5 and R.sub.6 each represent an alkyl group having 1 to 18 carbon atoms, R.sub.7 represents a hydrogen atom or an alkyl group have 3 to 12 carbon atoms, n is an integer of 1 to 3, and when n is 2 to 3, R.sub.7 may be the same or different, and when n is 1, R.sub.7 represents the above-mentioned alkyl group, and a high-boiling coupler solvent incompatible with water, and the weight ratio of said high-boiling coupler solvent to the coupler is 3.5 to 10.0.
