Abstract

L’invention concerne une feuille à degré élevé de blancheur comprenant un papier comportant un agent blanchissant fluorescent incorporé et, posé sur sa surface, une couche d’une résine soluble dans l’eau pour film de revêtement ou une couche d’un mélange d’une résine soluble dans l’eau pour film de revêtement et d’une autre résine soluble dans l’eau, présentant ainsi un degré de blancheur de 92 à 98 %. La quantité de résine soluble dans l’eau pour film de revêtement utilisée dans ladite feuille s’inscrit de préférence dans la plage de 0,6 à 5 g/m2 par rapport aux deux surfaces principales du papier. En outre, on préfère que la résine soluble dans l’eau pour film de revêtement soit au moins un élément sélectionné parmi l’alcool polyvinylique, le polyacrylamide et la carboxyméthylcellulose. Ainsi, on peut obtenir une feuille d’un degré élevé de blancheur qui, même lorsqu’une main est mise en contact avec la surface d’une telle feuille comportant un agent blanchissant fluorescent incorporé, ne fait pas coller l’agent blanchissant fluorescent à la main et qui peut être utilisée à la fois pour le transfert électrophotographique et l’impression par jet d’encre non seulement en noir et blanc, mais aussi en couleur.
