CA 2643858

Coated substrates are made from colored paper coated with a coating comprising silica or fumed metal oxide, such as precipitated silica, colloidal silica, fumed silica or fumed metal oxide. An opaque coating is formed which improves the L* and b* values of the colored paper. Images printed onto the paper show improved characteristics, such as a reduction in wick or bleed, or an improved color gamut.

L'invention porte sur des substrats de papier enduits dont le revêtement comporte de la silice, ou un oxyde métallique pyrogéné, tel que de la silice précipitée, de la silice colloïdale ou un oxyde métallique pyrogéné. On obtient ainsi un revêtement améliorant les coefficients L* et b* du papier de couleur. Les images imprimées sur ce papier ont des caractéristiques améliorées telles qu'une réduction de la capillarité et du coulage, et un accroissement de la gamme de couleurs.
