Abstract

Zeolite is a pigment that can be easily obtained with a large amount of domestic reserves and has excellent hydrophilicity due to its porous structure. In addition, it has the advantage of simple processing without the need for chemical modification and has the great advantage of being inexpensive. In this study, GCC, PCC, and zeolite, which have a large amount of domestic reserves and have a porous structure, were blended and applied as pigments for the pre-coating layer of printing paper. The applicability of zeolites was evaluated by comparative analysis of the surface properties and printability of coated papers. As a result, it was confirmed that when zeolite having a large particle size was blended as a pigment in the pre-coating layer, smoothness and gloss of the coated papers decreased. In addition, it was found that the optical properties were inferior compared to those of other pigments due to the unique color of zeolite.
