Abstract:
The aqueous ink white pigment of the present embodiment contains a metal compound (1) which satisfies the following specific conditions of (A), (B), and (C). (A) The metal compound (1) described above includes titanium dioxide, and a metal compound (2) where a refractive index at a wavelength of 550 nm is 1.60 or more and 2.45 or less, when the total of the titanium dioxide described above and the metal compound (2) described above is 100 wt %, the content of the titanium dioxide described above is 50 wt % or more and 99 wt % or less and the content of the metal compound (2) described above is 1 wt % or more and 50 wt % or less. (B) The peak value of the volume particle size distribution of the metal compound (1) which is measured with a dynamic light scattering method is in a range of 100 to 700 nm. (C) The pore volume of the metal compound (1) described above which is calculated with the BJH (Barrett-Joyner-Halenda) method is 0.1 ml/g or more and 0.65 ml/g or less.
