Title:
INK, INK CONTAINER, AND RECORDING APPARATUS
Document Type and Number:
Japanese Patent JP2018165321
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ink excellent in jetting stability, and preventing letters from bleeding.SOLUTION: An ink includes a coloring agent, an organic solvent, and water. The initial viscosity at 25°C is 7.5 mPas or more and 8.5 mPas or less. The ink satisfies the following numerical expression 1 when an evaporation rate x of the ink is any value of 30 mass% and 40 mass%: {1.085+η(0)}-1≤η(x)≤{1.110+η(0)}-1. where η(0) and η(x) represent a value of the initial viscosity (mPas), and a value of viscosity (mPas) at 25°C when the evaporation rate of the ink is x mass% in the numerical expression 1, respectively.SELECTED DRAWING: None
