Abstract
Herein is disclosed a method of electrostatic printing and foiling comprising: forming a colored 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 an adhesive toner image disposed on the colored 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; and forming a foiled image disposed on the adhesive toner image by heating the print substrate to at least partially melt the adhesive toner image and applying a foiling material to the print substrate such that the foiling material adheres to the at least partially molt…
