Abstract
ABSTRACT This study was carried out to elucidate the partial substitutability of SB latex with envi-ronmental-friendly coating binders for coated paper. Starch-based biobinder, ethylene vinyl acetate and acryl-based binder were evaluated for this purpose. Several combina-tions 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, eth-ylene 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 man-ufactured through 20% and 30% substitution of SB latex by biobinder and EVAc were im-proved, but dry- and wet-pick strength were decreased. The research works on the im-provement 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.Keywords: SB latex, biobinder, synthesized binder, top-coating, printability
