The present disclosure provides a white ink comprising an aqueous ink vehicle, a white colorant, and latex particles. The colorant can consist essentially of metal oxide particles present at from 2 wt% to 50 wt%, can have an average particle size from 100 nm to 1000 nm, and can have a high refractive index from 1.8 to 2.8. The latex can be present in the ink at from 2 wt% to 20 wt%, can have a glass transition temperature from 0° C to 130° C, and can have a low refractive index from 1.3 to 1.6. The metal oxide particles and latex particles can be present in the white ink at weight ratio is from 6:1 to 1:3. |
