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 γa (mN/m) of an ink A having relatively higher lightness at a lifetime of 500 milliseconds and dynamic surface tension γb (mN/m) of an ink B having relatively lower lightness at a lifetime of 500 milliseconds satisfy −5≦(γa−γb)≦3.
