ABSTRACT:
A pigment dispersion liquid comprises pigment particles dispersed in a dispersion medium, the difference (D90−D10) between D90and D10being not more than 25 nm, wherein D90and D10represent the primary particle size that the pigment particles having a primary particle size up to and including D90account for 90% by number of the total pigment particles, and the particle size that the pigment particles having a primary particle size up to and including D10account for 10% by number of the total pigment particles, respectively, in the integral of the primary particle size distribution function dG=f(D)dD of the pigment particles in which G is a particle number (%) and D is a primary particle size (nm).
