Abstract:
Herein is disclosed a method of electrostatic printing and glossing comprising: forming a first toner image on a print substrate by electrostatically printing an electrostatic ink comprising a first resin component comprising an ethylene acrylic acid resin, an ethylene methacrylic acid resin or combinations thereof; forming a second toner image disposed on the first toner image on the print substrate by electrostatically printing a liquid electro photographic (LEP) printing composition comprising a first resin component comprising an ethylene acrylic acid resin, an ethylene methacrylic acid resin or combinations thereof, and a second resin component present in an amount of about 20% to about 80% by weight of total solids content of the LEP printing composition, the second resin component having a melting point of from about 50° C. to about 75° C., which is below the melting point of the first resin component, or from about 140° C. to about 180° C., which is above the melting point of the first resin component; heating the print substrate to at least partially melt the first or second toner image.
