| Résumé : |
Titanium dioxide (TiO2) is traditionally used as a white pigment in water-and solvent-base liquid inks. High levels (more than 30wt%) are typically required to achieve an acceptable level of opacity at low print thickness, but at these levels the pigment particles can become significantly crowded, resulting in a decraese in scattering efficiency and hiding power. Pulverised ultrafine kaolin can be added to achieve similar print gloss and print density/opacity at reduced TiO2 level in white flexographic ink formulations. |
