INK SET, INK JET RECORDING METHOD, INK CARTRIDGE, RECORDING UNIT, INK JET RECORDING METHOD, AND AQUEOUS INK |
摘要 |
An ink set is provided which can suppress bleeding irrespective of the type of recording medium. The ink set includes a plurality of aqueous inks each containing a dye, and has at least a first aqueous ink containing a dye, wherein the difference between the dynamic surface tension of the first aqueous ink at a lifetime of 50 milliseconds and the dynamic surface tension of the first aqueous ink at a lifetime of 500 milliseconds is 7 mN/m or more; and, between the first aqueous ink and at least one type of aqueous ink except the first aqueous ink included in the ink set, dynamic surface tension gamma<SUB>a </SUB>(mN/m) of an ink A having relatively higher lightness at a lifetime of 500 milliseconds and dynamic surface tension gamma<SUB>b </SUB>(mN/m) of an ink B having relatively lower lightness at a lifetime of 500 milliseconds satisfy -5<=(gamma<SUB>a</SUB>-gamma<SUB>b</SUB>)<=3.
