Title (EN) COATED PAPER FOR USE IN PRINTING
(FR) PAPIER COUCHÉ DESTINÉ À ÊTRE UTILISÉ DANS L'IMPRESSION
(JA) 印刷用塗工紙
Abstract:
(EN) The present invention provides a coated paper for use in printing, the coated paper having a base paper and a coating layer on at least one surface of the base paper, and being configured such that: an outermost coating layer, which is positioned farthest outside in the coating layer with reference to the base paper, contains at least kaolin, calcium carbonate, starches, latex, a dispersant, a lubricant, and a cationic resin; with respect to 100 parts by mass of pigments within the outermost coating layer including kaolin and calcium carbonate in the outermost coating layer, the total of the starches and the latex is 5-13 parts by mass, the dispersant is 0.02-0.3 parts by mass, the lubricant is 0.25-0.6 parts by mass, and the cationic resin is 0.25-0.5 parts by mass; the content ratio by mass for the kaolin and calcium carbonate within the outermost coating layer is such that kaolin:calcium carbonate = 1:9 to 6:4; and the content ratio by mass of the starches and the latex in the outermost coating layer is such that starches:latex = 1:9 to 4:6. The present invention thereby makes it possible to provide a coated paper for use in printing that is resistant to printing stains, color concentration discrepancies, and dullness.
(FR) La présente invention concerne un papier couché destiné à être utilisé dans l'impression, le papier couché ayant un papier de base et une couche de revêtement sur au moins une surface du papier de base, et étant conçu de telle sorte que : une couche de revêtement la plus extérieure, qui est positionnée le plus loin à l'extérieur dans la couche de revêtement par rapport au papier de base, contient au moins du kaolin, du carbonate de calcium, des amidons, du latex, un dispersant, un lubrifiant et une résine cationique ; par rapport à 100 parties en masse de pigments à l'intérieur de la couche de revêtement la plus extérieure comprenant du kaolin et du carbonate de calcium dans la couche de revêtement la plus extérieure, le total des amidons et du latex est de 5-13 parties en masse, le dispersant est de 0,02 à 0,3 partie en masse, le lubrifiant est de 0,25 à 0,6 partie en masse, et la résine cationique est de 0,25 à 0,5 partie en masse ; le rapport de teneur en masse pour le kaolin et le carbonate de calcium à l'intérieur de la couche de revêtement la plus extérieure étant tel que le rapport kaolin:carbonate de calcium = 1:9 à 6:4 ; et le rapport de teneur en masse des amidons et du latex dans la couche de revêtement la plus extérieure est tel que le rapport amidons:latex = 1:9 à 4:6. La présente invention permet ainsi de fournir un papier couché destiné à être utilisé dans l'impression qui est résistant aux taches d'impression, aux divergences de concentration de couleur et à la ternissure.
(JA) 本発明は、原紙と、前記原紙の少なくとも片面に塗工層とを有し、前記塗工層において原紙を基準として最外に位置する最外塗工層がカオリン、炭酸カルシウム、澱粉類、ラテックス、分散剤、滑剤およびカチオン性樹脂を少なくとも含有し、最外塗工層においてカオリンおよび炭酸カルシウムを含む最外塗工層中の顔料100質量部に対して、澱粉類およびラテックスの合計が5質量部以上13質量部以下、分散剤が0.02質量部以上0.3質量部以下、滑剤が0.25質量部以上0.6質量部以下、並びにカチオン性樹脂が0.25質量部以上0.5質量部以下であり、且つ最外塗工層中のカオリンと炭酸カルシウムとの含有質量比が、カオリン:炭酸カルシウム=1:9~6:4であり、且つ最外塗工層において澱粉類とラテックスとの含有質量比が、澱粉類:ラテックス=1:9~4:6である印刷用塗工紙を提供することである。 本発明により、耐印刷汚れ性、耐色濃度ムラ性および耐くすみ性を有する印刷用塗工紙を提供することができる。
