Abstract
An ink set for ink-jet recording includes a black ink containing a black pigment having an average particle size of from about 100 nm to about 150 nm, and color inks containing color pigments having an average particle size of from about 60 nm to about 90 nm. The dynamic surface tension of the black ink is from about 40 mN/m to about 45 mN/m, and the dynamic surface tension of each of the yellow ink, the magenta ink and the cyan ink is from about 35 mN/m to about 40 mN/m measured on the condition of 25° C. according to a maximum bubble pressure method at lifetime of 100 ms.
