CA 2291325

A printing medium comprising: (a) a substrate having at least one surface; and (b) a coating on the surface wherein the coating comprises: (1) binder comprising organic polymer, wherein poly(ethylene oxide) having a weight average molecular weight in the range of from 100,000 to 3,000,000 constitutes from at least 5 up to less than 20 percent by weight of the organic polymer of the binder and wherein the organic polymer of the binder constitutes from 20 to 80 percent by weight of the caoting; and (2) finely divided substantially water-insoluble filler particles which have a maximum dimension of less than 500 nanometers, are distributed throughout the binder, and constitute from 20 to 80 percent by weight of the coating.

Support d'impression comportant (a) un substrat présentant au moins une surface et (b) un revêtement déposé sur cette surface. Ce revêtement renferme (1) un liant contenant un polymère organique représentant entre 20 et 80 % en poids du revêtement et dans lequel le poly(oxyde d'éthylène), au poids moléculaire moyen situé entre 100 000 et 3 000 000, représente entre 5 et 20 % en poids dudit polymère organique; et (2) des particules de remplissage sensiblement insolubles dans l'eau, finement divisées et présentant une dimension maximale inférieure à 500 nanomètres, qui sont réparties dans tout le liant et représentent entre 20 et 80 % en poids du revêtement.
