The application of nanosilica in coating of art paper and ink-jet paper is studied. The results show that when nanosilica is used in art paper coating, the dispersity and flowability of the art paper coating are excellent. The surface strength, smoothness and gloss of the paper coated with art paper coating with nanosilica are improved and its yellowing rate is decreased. When nanosilica is used in ink-jet paper coating, the dispersity of prepared ink-jet paper coating is of better, the coated paperboard with ink-jet paper coating with nanosilica is of ink transfer larger, K&N value higher and whiteness higher. The smoothness and gloss of paperboard coated with ink-jet paper coating with silica are improved. The combination application of more kinds of adhesives improves the print gloss of paperboard coated with ink-jet paper coating with silica.
