PURPOSE:To enhance raw storage stability by dispersing a dye producing compound and/or a dispersion resistant reducing agent into an organic solvent specified in viscosity and dielectric constant and high in boiling point. CONSTITUTION:The dye producing compound and/or the dispersion resistant reducing agent are dispersed into the organic solvent having a viscosity at 25 deg.C of >=50cp and a dielectric constant of <=10, and it is preferred to select the compound having a melting point of >=10 deg.C and up to a temperature of 20 deg.C higher than a developing temperature and a dielectric constant of 9-1 in order that said reducible dye-producing compound sufficiently reacts with said dispersion resistant agent in said solvent at the time of development, and said dispersion has excellent raw storage stability. |
