摘要:
The present invention aims to provide coated papers for newsprint inks having fast ink drying properties comparable to those of conventional newsprint papers, without stickiness, and having good reproduction and sharpness of printed images comparable to those of coated papers printed using penetration drying type inks; as well as processes for preparing them. The invention provides for a coated printing paper for newsprint inks comprising a coating layer containing a pigment and an adhesive on a base paper, characterized in that the coating layer on the base paper has a coat weight of 4.0 g/m2 or more per side and that the coated paper has an oil absorbency under pressure of 20 g/m2 or more and a Bekk smoothness of 75 seconds or less; as well as a process for preparing the paper.
