Abstract
Abstract An ink-jet recording method is provided which employs inks of at least one color and a plurality of inks different in dye concentration for each color. The method is characterized in that the viscosities of the plurality of inks of the same color in the temperature range of 0° to 40° C. satisfy the relation V.sub.max. -V.sub.min. ≦1.0 (cps) wherein, V max . and V min . represent the maximum and minimum values, respectively, of these viscosities.
