Abstract
This study was carried out to elucidate the partial substitutability of SB latex with environmental-friendly coating binders for coated paper. Starch-based biobinder, ethylene vinyl acetate and acryl-based binder were evaluated for this purpose. Several combinations of above binders were applied to top layer coating, and properties of coating colors and printability were evaluated. When 20% and 30% of SB latex were substituted by acryl-based synthetic binder, ethylene vinyl acetate and biobinder, the brightness, whiteness and opacity of coated paper were similar to those obtained from SB latex. Ink set and stiffness of coated paper manufactured through 20% and 30% substitution of SB latex by biobinder and EVAc were improved, but dry- and wet-pick strength were decreased. The research works on the improvement of dry- and we-pick strength, mechanical stability and rheological properties at high shear condition should be continued for the commercial application of biobinder, EVAc and acryl-based binder.
