Abstract

L'invention concerne des feuilles pour impression à jet d'encre présentant un brillant élevé, une haute densité d'impression, une excellente absorption d'encre et une bonne reproductibilité chromatique et graphique. L'invention concerne en particulier une feuille pour impression à jet d'encre comprenant un support et une couche conférant le brillant, cette couche étant réalisée par couchage sur le support et contenant un agent de rétention d'eau et des fines inorganiques dont le diamètre particulaire primaire est égal ou inférieur à 100 nm. Le fluide de revêtement qui constitue la couche conférant le brillant a un rapport de déshydratation sous pression de préférence inférieur à 75 %. La teneur de l'agent de rétention d'eau va de préférence de 0,5 à 5 % en masse, cet agent étant de préférence un polymère comportant des groupes carboxyle. Les fines particules organiques de la couche conférant le brillant ont de préférence un diamètre particulaire primaire inférieur ou égal à 100 nm. La feuille est de préférence pourvue d'une couche de réception de l'encre contenant un pigment inorganique poreux entre le support et la couche conférant le brillant.
