<P>PROBLEM TO BE SOLVED: To provide an ink set for inkjet recording capable of increasing the optical density (OD value) of a recorded object and excellently suppressing ink bleeding in an recorded image. <P>SOLUTION: The ink set containing a water-based ink for inkjet recording and a treatment liquid. The water-based ink contains a phosphate group-modified self-dispersing pigment, water, and a water-soluble organic solvent. The treatment liquid contains an aggregating agent, water, and a water-soluble organic solvent. A dynamic surface tension of the water-based ink, measured under the condition where a life time is about 50 ms, is in the range of 35 to 45 mN/m. A dynamic surface tension of the treatment liquid, measured under the condition where a life time is about 50 ms, is in the range of 33 to 45 mN/m. <P>COPYRIGHT: (C)2012,JPO&INPIT |
