Abstract
The present invention is relative with a water color ink suited for ink jet printing for plain paper. The dry viscosity, the dynamic surface tension at 10 ms and the dynamic surface tension at 1000 ms of the ink are prescribed to be equal to 100 mPa·s or less, equal to 45 mN/m or higher and equal to 35 mN/m or less to provide for reduced bleeding and superior drying performance and emission reliability.
