RESIN-FORTIFIED EMULSION POLYMERS FOR WATER-BORNE INKS AND THE METHOD FOR PREPARING THE SAME

摘要

Disclosed are resin-fortified emulsion resins for water-borne inks and a method for preparing the same. In preparing resin-fortified emulsion resins, a styrene/acrylic acid water-soluble resin is added in advance before the initiation of emulsion polymerization. The water-soluble resin provides the sites where the reaction can occur like conventional emulsifiers. Therefore, the emulsion resins suitable for use in water-borne inks can be obtained without using additional ionic emulsifiers. In addition, resin-fortified emulsion resins can be used in a variety of applications because of their broad ranges of acid number and glass transition temperature.
