摘要：
An ink composition has a viscosity of 25 mPa·s to 35 mPa·s at 20° C., wherein a, b, and c are 800 or more, 7.4 to 14, and 0.16 to 0.22, respectively, when a cylindrical portion is formed by expanding the ink composition so as to have a free surface parallel to the expanding direction of the ink composition, the rate of change in width of the cylindrical portion with time is measured in the expanding direction thereof, and the rate of change in width of the cylindrical portion with time is fit to a quadratic function given by the following equation: S=−at2−bt+c (1) where S is the rate of change in width of the cylindrical portion and t is the time in seconds.
