A printing medium comprising a substrate having at least one surface and a coating on the surface wherein the coating comprises: (a) binder comprising: (1) organic polymer which is substantially free of onium groups, and (2) onium addition polymer consisting essentially of onium-containing mer units derived from addition monomer and onium-free mer units derived from addition monomer of which from 20 to 100 percent by weight is hydrophobic addition monomer, wherein the binder constitutes from 20 to 90 percent by weight of the coating; and (b) finely divided substantially water-insoluble pseudoboehmite particles which have a maximum dimension of less than 500 nanometers, are distributed throughout the binder, and constitute from 10 to 80 percent by weight of the coating. An aqueous coating composition comprising the above binder and pseudoboehmite particles is also described.

L'invention porte sur un support d'impression comprenant un substrat pourvu d'au moins une surface sur laquelle est appliqué un revêtement qui comprend: (a) un liant renfermant (1) un polymère organique pratiquement exempt de groupes onium, et (2) un polymère d'addition d'onium renfermant principalement des unités mer contenant un onium et dérivées d'un monomère d'addition, et des unités mer sans onium dérivées également d'un monomère d'addition et dont 20 à 100 % en poids est un monomère d'addition hydrophobe, le liant constituant de 20 à 90 % en poids du revêtement; et (b) des particules de pseudobohémite, finement divisées et pratiquement insolubles dans l'eau qui ont une dimension maximale inférieure à 500 nanomètres, sont réparties dans la totalité du liant et constituent de 10 à 80 % en poids du revêtement. L'invention porte également sur une composition de revêtement aqueuse comprenant le liant précité et des particules de pseudobohémite.
