Media coatings for use on substrates for ink jet printing include a cationically modified clay, a cationically modified silica and a binder. Alternatively, the media coatings also include additional additives. The ratio of cationically modified clay to cationically modified silica varies in the coating formulation from about 1 % to about 99 %. Desirably, the ratio of the cationically modified clay to cationically modified silica varies from about 10 % to about 50 %. More desirably, the ratio of cationically modified clay to cationically modified silica varies from about 25 % to about 35 %. The ratio of the total cationically modified clay and cationically modified silica to binder varies from about 20 % to about 80 %. Desirably, the ratio of the total cationically modified clay and cationically modified silica to binder varies from about 65 % to about 75 %.
L'invention concerne des revêtements de support utilisés sur des substrats pour impression par jet d'encre, comprenant de l'argile cationiquement modifiée, de la silice cationiquement modifiée, et un liant. Selon un autre mode de réalisation, les revêtements de support comprennent également des additifs supplémentaires. Dans la formulation de revêtement, la proportion argile cationiquement modifiée/ silice cationiquement modifiée varie d'environ 1 % à 99 %. Elle varie, de préférence d'environ 10 % à 50 %, et idéalement d'environ 25 % à 35 %. La proportion entre la totalité de l'argile cationiquement modifiée et de la silice cationiquement modifiée/liant varie d'environ 20 % à 80 %, cette proportion variant, de préférence, d'environ 65 % à 75 %.
