Abstract

The invention addresses the problems of providing a coated paper having an excellent property of paper alignment, providing a coated base material having an excellent property of ink drying, and providing a method of accurately evaluating the property of ink drying. The first problem is solved by a coated paper for printing that has a white-paper glossiness of less than 30% according to JIS-P8142,and a kinetic coefficient of friction greater than the static coefficient of friction, in terms of the static coefficient of friction and kinetic coefficient of friction measured according to ISO 15359. The second problem is solved by a coated base material having a sheet base material and a pigment coating layer provided thereon, the pore volume V of the pigment coating layer according to nitrogen adsorption being 0.04 cm3 / g or greater. The third problem is solved by a method that includes a step of measuring the pore volume V or the average pore diameter m of the pigment coating layer by nitrogen adsorption.

Description

technical field

[0001] The present invention relates to a coated paper, a coated substrate, a method for producing the same, and a method for evaluating ink drying properties. More specifically, the present invention relates to a coated paper for matte printing and a method for producing the same. Background technique

[0002] A coated base material having a coating layer on a sheet-like base material is used in various applications including printing applications. Coated paper in which the sheet-like base is paper (base paper) is also industrially particularly important among coated base materials.

[0003] Coated paper is roughly classified into glossy coated paper and matte coated paper. Gloss coated paper includes art paper, super art paper used in high-end printing in the past, or coated paper used in catalogs, brochures, etc., which are printed and finished to form a glossy white paper with high gloss and printing gloss. . Matte coated paper is a coated paper with ...
