摘要

PROBLEM TO BE SOLVED: To provide an ink that prevents the deposition of titanium dioxide as a coloring agent and is capable of easily re-dispersing titanium dioxide even when it is deposited.SOLUTION: There is provided an ink containing titanium dioxide and water, where average value (%) M of supernatant relative change amount percentage after standing at 25°C for 240 hours by integration of back scattered light strength peak with the deposition of the titanium dioxide in the ink and viscosity η(mPa s) at 25°C of a liquid after removing the titanium dioxide from the ink satisfy the formula [(M×η)]/10<10.SELECTED DRAWING: None
