<p>333A white inkjet ink including a liquid ink vehicle; a first inorganic pigment with a refractive index greater than 1.60 having an average particle size A larger than 200 nm; and a second inorganic pigment having an average particle size B between 40 nm and 90 nm; wherein the number of particles per mm NAB complies with the relation : Formula (I) with NA representing the number of particles per mm having a particle size in the range of A 20 nm to A + 20 nm; NB representing the number of particles per mm having a particle size in the range of B 20 nm to B + 20 nm; and wherein the average particle size A is measured by transmission electron microscopy at a 13 500x magnification on a 10 pm thick coated layer of the white inkjet ink for all inorganic particles having a particle size larger than 100 nm; the average particle size B is measured by transmission electron microscopy at a 58 000x magnification on the same 10 pm thick coated layer of the white inkjet ink for all inorganic particles having a particle size of no more than 100 nm.</p> |
