| titleOfInvention | Direct positive color photographic material |
| abstract | A direct positive color photographic material having comprising a support at least one previously non-fogged internal latent image-type silver halide emulsion, in which at least one green-sensitive internal latent image-type silver halide emulsion layer contains a 2-equivalent yellow-coloring coupler and a magenta-coloring coupler of the following general formula (M-II) ##STR1## where R 10 represents a hydrogen atom or a substituent; n Y 4 represents a hydrogen atom or a removing group; n Za, Zb and Zc each represents a methine group, a substituted methine group, ═N-- or --NH--; n one of the Za--Zb bond and the Zb--Zc bond is a double bond and the other is a single bond; and when the Zb--Zc bond is a carbon-carbon double bond, it may be part of an aromatic ring; and n a dimer or a polymer at the position of R 10 or Y 4 or at the position of Za, Zb or Zc when Za, Zb or Zc is a substituted methine group is formed, where the relative coupling rate of the 2-equivalent yellow-coloring coupler to the magenta-coloring coupler is within the range of from 0.5 to 2.0, and at least one layer of the photographic material contains at least one compound selected from the group consisting of compounds of the following general formulae (II) and (III): ##STR2## where Q represents an atomic group necessary for forming a 5-membered or 6-membered hetero ring, which may be condensed with a carbocyclic-aromatic ring or heterocyclic-aromatic ring; n L represents a divalent linking group composed of one or more atoms selected from hydrogen, carbon, nitrogen, oxygen and sulfur atoms; n R 3 represents an organic group containing at least one of a thioether group, an amino group, an ammonium group, an ether group and a heterocyclic group; n n represents 0 or 1; m represents 0, 1 or 2; and n M represents a hydrogen atom, an alkali metal atom, an ammonium group, or a group capable of being cleaved under alkaline conditions. ##STR3## where Q' represents an atomic group necessary for forming a 5-membered or 6-membered heterocyclic ring which may form an imino silver; n L, R 3 , n and M have the same meaning as in the above-mentioned formula (II); and n p represents 1 or 2. |
