Abstract: The present invention provides plain printing paper comprising a paper substrate containing, as main components, cellulose pulp and calcium carbonate as a filler, and an optional cationic resin and a multivalent cation salt attached onto the paper substrate, wherein the total amount of the cationic resin and the multivalent cation salt attached on both surfaces of the paper substrate is 1.0 g/m2 to 5.0 g/m2, both inclusive, and the mass ratio of the cationic resin to the multivalent cation salt is 0:100 to 90:10, both inclusive.

Abstract: The object of the present invention is to provide a coated printing paper used for ink jet printing machines, which has an ink fixing property and ink absorption property corresponding to ink jet printing, which inhibits poor dot diffusion, and which is excellent in abrasion resistance property of printed portions. According to the present invention, provided is a coated printing paper comprising a base paper, an undercoating layer which is applied on at least one surface of the base paper and contains a pigment and a binder, and one or more coating layers on the undercoating layer, wherein the base paper contains at least one selected from a cationic resin and a multivalent cation salt; the uppermost coating layer contains at least a colloidal silica; and the 75° gloss according to JIS Z8741 of the surface of the uppermost coating layer is 40% or more.

Abstract: A coated printing paper has a favorable offset printability, which can achieve good ink fixing and ink absorption properties even in ink jet printing, which has suitable dot diffusion even when printed by an ink jet printer using pigment ink, and can prevent the occurrence of white lines. The coated printing paper comprises a base paper and a coating layer which is applied to at least one surface of the base paper and contains a pigment and a binder as major components, wherein the base paper comprises a cationic compound, the coating layer contains, as a pigment, 50 parts by mass or more of ground calcium carbonate based on 100 parts by mass of total pigments in the coating layer, and the applied amount of the coating layer is 2.0 g/m2 to 7.0 g/m2, both inclusive, per surface.
