Abstract
A method of making a liquid electrophotographic (LEP) paste is disclosed herein. A base paste is made by forming a dispersion of a pigment and a non-polar carrier, adding a transparent resin dispersion to the pigment dispersion to form a dispersion mixture, and homogenizing the dispersion mixture. The transparent resin dispersion includes a polymer dispersed in a non-aqueous carrier. The homogenizing may be accomplished by agitating the dispersion mixture at a frequency of less than 1 kHz, thereby forming the paste.
