<p><P>PROBLEM TO BE SOLVED: To provide an ink set which does not cause solvent shock, is excellent in detergency, and can stably be discharged from a head of an inkjet printer. <P>SOLUTION: The inkjet ink set includes an inkjet ink containing at least a pigment, a dispersant, a binder resin and an organic solvent, and a cleaner for the inkjet ink, wherein if the limiting viscosity at 25°C of the cleaner when the dispersant is dissolved therein is taken to be [η<SB POS="POST">d</SB>] (dl/g), and the weight-average molecular weight of the dispersant is taken to be M<SB POS="POST">d</SB>, M<SB POS="POST">d</SB>/[η<SB POS="POST">d</SB>] satisfies 2,500≤M<SB POS="POST">d</SB>/[η<SB POS="POST">d</SB>]≤6,000; and if the limiting viscosity of the cleaner when the binder resin is dissolved therein is taken to be [η<SB POS="POST">b</SB>](dl/g), and the molecular weight of the binder resin is taken to be M<SB POS="POST">b</SB>, M<SB POS="POST">b</SB>/[η<SB POS="POST">b</SB>] satisfies M<SB POS="POST">b</SB>/[η<SB POS="POST">b</SB>]≤3,500. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
