Method of preparing dye solution, and methods of producing silver halide emulsion and silver halide photographic material

   
   

A method of preparing a dye solution having a high concentration and high stability, wherein a counter ion-free dye and a base having a pKa value of from 6.6 to 9.0 are dissolved in a solvent having a relative dielectric constant of at least 10 at 20.degree. C., and a silver halide emulsion and a silver halide photographic material which are reduced in fogging by the use of the dye solution prepared in accordance with the aforesaid method.
