ABSTRACT:
A color reversal image forming process using a color reversal photographic material is disclosed. The process comprises an exposure step, a black and white development step, a reversal step, a color development step and a desilvering step. The color reversal photographic material comprises a support and one or more silver halide emulsion layers. According to one embodiment of the present invention, at least one silver halide emulsion layer comprises silver halide containing chloride of not less than 90 mole %, iodide of 0 mole % and bromide of not more than 10 mole %. According to another embodiment, at least one silver halide emulsion layer comprises silver halide containing chloride of not less than 88 mole %, iodide of 0.1 to 2 mole % and bromide of not more than 10 mole %. The silver halide emulsion layer further contains a compound represented by the formula (Ia) or (Ib): ##STR1## wherein R.sup.11 is an alkyl group, an alkenyl group, a heterocyclic group or an aryl group; X.sup.1 is hydrogen, an alkali metal atom, an ammonium group or a precursor thereof; V.sup.1 is an oxygen atom, a sulfur atom, .dbd.NH or .dbd.N--(L).sub.n, --R.sup.12 ; L is a divalent linking group; and n is 0 or 1.
