The recent popularity of ink jet printers has led to the invention of an entire new line of paper coatings. These formulations often require cationic additives to achieve proper print quality. The effect of these cationic additives and their interaction with latexes is studied. This project investigated whether a high solids ink jet coating applied via blade coating can give satisfactory print quality, and the extent of interactions among latex and cationic additives (delete). The experimental design consisted of two different base formulations that were varied by addition levels of polyvinylpyrollidone (PVP), silica, latex, and cationic polymer. These formulations were evaluated by assessing their runnability on a cylindrical laboratory coater and determining the coating rheology as well as the overall optical, structural, and print properties.
