The present invention relates to a sizing composition that, when applied to paper substrate, creates a substrate, preferably suitable for inkjet printing, having increased print density, and print mottle, as well as print sharpness, low HST, and/or image dry time, the substrate preferably having high brightness and reduced color-to-color bleed as well. In addition, the present invention relates to a method of reducing the HST of a paper substrate by applying the sizing composition to at least one surface thereof. Further, the application relates to methods of making and using the sizing composition, as well as methods of making and using the paper containing the sizing composition.
La présente invention concerne une composition dencollage qui, lorsquelle est appliquée sur un substrat de papier, crée un substrat de préférence approprié pour une impression par jet dencre, avec une densité dimpression et une marbrure dimpression accrues, ainsi quune netteté dimpression, une faible valeur de HST, et/ou de temps de séchage de limage, le substrat présentant de préférence une brillance élevée et également une migration réduite entre les couleurs. En outre, la présente invention concerne un procédé de réduction de la valeur HST dun substrat de papier par lapplication de la composition dencollage à au moins une surface de celui-ci. De plus, lapplication concerne des procédés de fabrication et dutilisation de la composition dencollage, ainsi que des procédés de fabrication et dutilisation du papier qui contient la composition dencollage.
