Abstract
A water-based white pigment ink for ink-jet recording includes a white pigment and water. The ink further includes a first resin emulsion having a tensile elongation from 600% to 1200% as a film, measured in accordance with JIS K 7127 and a second resin emulsion having a maximum tensile stress from 50 MPa to 80 MPa as a film, measured in accordance with JIS K 7127. The solid content (R1) of the first resin emulsion to be added and the solid content (R2) of the second resin emulsion to be added in the total amount of the ink satisfy R1/R2=0.4 to 2.5.
