PROBLEM TO BE SOLVED: To provide a color developing concentrated kit (concentrated composition) free of deterioration in coloration even after storage with time, particularly storage at high temperature, maintaining the value as a product even after long-term storage and capable of retaining stable performance with respect to photographic performance as a color developing concentrated kit (concentrated composition) containing a p-phenylenediamine-base color developing agent. SOLUTION: The color developing concentrated composition for a silver halide photographic sensitive material contains≥0.2 mol/L p-phenylenediamine- base color developing agent, has≤0.5 mol/L concentration of sulfurous acid and≤pH 7.0 and further contains a compound of formula [1].
