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