To obtain a silver halide photosensitive material improved in long-term stability by adding water-miscible solution containing a specified compound and a specified colorant to a silver halide emulsion.

0.0000001-10g/l of a compound represented by formula I (wherein R1 to R5 are each H, an alkyl or an aryl, provided at least two of them are carboxylakyls or alkylesters thereof, (h) and (i) are each 2 or 3; (j) is 0-2; and (k) is 0 or 1) and a red sensitizing colorant represented by formula II or III [wherein Z1 to Z3 are each an atomic group necessary to form a five- or six- membered nitrogenous heterocyclic ring; D and D' are each an atomic group necessary to form an (a) cyclic acid e nucleus; R1 to R3 are each an alkl; L1 to L21 are each a (substituted) methine; n1 to n4 and (j) are each 0 or 1; M1 and M2 are each a counter ion neutralizing the charge; m1 and m2 are each a number necessary to neutralize the charge of the molecule and equal to or greater than 0; and Z1 to Z3 are each a benzothiazole nucleus or the like] are dissolved in water or a water-miscible solution comprising water and a water- miscible organic solvent. This solution in such an amount that the amount of the compound represented by formula I is 1wt.% or below based on the silver atoms, is added to a silver halide emulsion.
