Abstract
Provided in one example herein is a liquid electrophotographic ink composition. The composition comprises a charge director; a non-polar carrier fluid comprising a polymer; and ink particles each comprising a polymeric resin mixture comprising a first polymeric resin having a first melting temperature and a second polymeric resin having a second melting temperature. The second polymeric resin may be a UV-curable polymer that is solid at room temperature, and the second melting temperature is lower than the first melting temperature.
