Direct positive type silver halide photographic material comprising a mixture of dyes

A direct positive silver halide photographic material containing at least one compound represented by the following formula (I) and at least one cyanine dye having a pyrazolo[5,1-b]quinazolone nucleus and a 5- or 6-membered nitrogen-containing heterocyclic ring, wherein a carbon atom at the 3-position of the pyrazolo[5,1-b]quinazolone nucleus is bonded through a four-methine chain to an atom at the 2-position or 4-position of the 5- or 6-membered nitrogen-containing heterocyclic ring, provided that the 4-position is possible only when the 5- or 6-membered nitrogen-containing heterocyclic ring is a quinoline or pyridine nucleus:

• ##STR92## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents an alkyl group, an aryl group or a heterocyclic group;
• V.sub.1, V.sub.2, V.sub.3, V.sub.4, V.sub.5, V.sub.6, V.sub.7 and V.sub.8 each represents a hydrogen atom or a monovalent substituent selected from the group consisting of an alkyl group, an aryl group, a heterocyclic group, a halogen atom, a mercapto group, a cyano group, a carboxyl group, a sulfo group, a hydroxyl group, a carbamoyl group, a sulfamoyl group, an amino group, a nitro group, an alkoxy group, an aryloxy group, an acyl group, an acylamino group, a sulfonyl group, a sulfonylamino group, an alkylthio group, an arylthio group, an alkoxycarbonyl group and an aryloxycarbonyl group;
• L.sub.1, L.sub.2 and L.sub.3 each represents a methine group;
• M.sub.1 represents a charge-neutralizing counter ion;
• and
