Abstract:
(EN) Provided is a print paper that has coating layers disposed on a base paper, wherein: an outermost coating layer comprises a pigment, a binder, a lubricant, a dispersant, and a cationic resin, and contains kaolin and calcium carbonate in an amount of 80 parts by mass with respect to 100 parts by mass of the pigment, the mass ratio of contents of the kaolin and the calcium carbonate being 1:9 to 6:4; and the outermost coating layer satisfies at least one of (I), (II), and (III). (I) When a droplet of an aqueous solution having a surface tension of 20 mN/m is placed on the outermost coating layer surface, the droplet and the outermost coating layer form a contact angle of 40-65° therebetween one second after contact. (II) The aqueous solution having a surface tension of 20 mN/m has a transfer rate of 5.0-12.0 ml/m2 in one second of contact time, as determined by the Bristow method. (III) The maximum peak value of specular reflection light amount of a point image is 2,000-30,000.
(FR) Papier d'impression qui comporte des couches de revêtement disposées sur un papier de base, dans lequel : une couche de revêtement la plus extérieure comprend un pigment, un liant, un lubrifiant, un dispersant et une résine cationique, et contient du kaolin et du carbonate de calcium en une quantité de 80 parts en masse par rapport à 100 parts en masse du pigment, le rapport de masse des teneurs du kaolin et du carbonate de calcium étant de 1:9 à 6:4 ; et la couche de revêtement la plus extérieure satisfaisant à au moins l'une parmi (I), (II), et (III). (I) Lorsqu'une gouttelette d'une solution aqueuse ayant une tension de surface de 20 mN/m est placée sur la surface de la couche de revêtement la plus extérieure, la gouttelette et la couche de revêtement la plus extérieure forment un angle de contact de 40 à 65° entre elles une seconde après contact. (II) La solution aqueuse ayant une tension de surface de 20 mN/m a une vitesse de transfert de 5,0-12,0 ml/m2 en une seconde de temps de contact, tel que déterminé par le procédé de Bristow. (III) La valeur de crête maximale de quantité de lumière de réflexion spéculaire d'une image ponctuelle est de 2 000 à 30 000.
(JA) 原紙上に塗工層を有する印刷用紙であって、最外塗工層が、顔料、バインダー、滑剤、分散剤およびカチオン性樹脂を含有し、カオリンおよび炭酸カルシウムの含有量が顔料100質量部に対して80質量部以上であり、並びにカオリンと炭酸カルシウムとの含有質量比が1:9~6:4であり、かつ、最外塗工層表面が、(I)、(II)および(III)の少なくともいずれかを満足する印刷用紙。 (I):表面張力が20mN/mである水溶液を滴下した時、液滴と最外塗工層との接触角が接触1秒後において40°以上65°以下である。(II):ブリストー法で求められる接触時間1秒において表面張力が20mN/mである水溶液の転移量が5.0ml/m以上12.0ml/m以下である。(III):点像の鏡面反射光量の最大ピーク値が2000以上30000以下である。
