Abstract
The study aim was to evaluate the effect of mixing of a water-soluble polymer, poly (vinyl alcohol) (PVA), and an emulsion binder, vinyl acetate ethylene (VAE), on the properties of the coating color and to identify the factors affecting the design of the coating color formulation for inkjet paper. The test compositions of the coating color used PVA and VAE emulsion binders of different molecular weights, and the properties of the prepared coating color and coated paper were analyzed. As the mixing ratio of the VAE emulsion to PVA increased, the viscosity of the coating solution decreased, but when the mixing ratio was constant, the coating color using low-molecular weight PVA had low viscosity. As the VAE emulsion mixing ratio and PVA molecular weight increased, the contact angle of the coated papers increased, but the ink density of the coated paper decreased.
