Abstract

This study was carried out to evaluate whether EVAc, acryl latex and biobinder could substitute the part of SB latex for pre-coating color formula or not. Different coating colors prepared through the substitution of 30% SB latex with EVAc, acryl latex, and biobinder were applied for pre-coating layer. 100% SB latex is used as a binder for top coating color. The optical properties, gloss, roughness, stiffness, dry- and wet-pick strength were measured. There were no significant differences in the brightness, whiteness, opacity, roughness, ink set-off and gloss of paper coated with 5 different coating colors. However the stiffness, dry- and wet-pick strength were somewhat lower than those of conventional coating color which 100% SB latex was used as a binder. Although the part of SB latex could be substituted with EVAc, acryl latex and biobinder without sacrificing the qualities of coated paper. Further researches on the improvement of stiffness, dry- and wet-pick strength, and the optimization of rheology of coating color in order to improve the qualities of coated paper are strongly recommended.
