Abstract
The present disclosure relates to an electrophotographic printing method comprising electrophotographically printing a liquid electrophotographic composition onto a substrate. The liquid electrophotographic composition comprises a charge adjuvant and a copolymer of a) ethylene and b) methacrylic acid and/or acrylic acid, wherein 80 to 95 weight % of the units of said copolymer are derived from ethylene. The printed substrate is then subjected to electron beam (EB) radiation.
Claims17
An electrophotographic printing method comprising:
- electrophotographically printing a liquid electrophotographic composition onto a substrate, wherein the liquid electrophotographic composition comprises a charge adjuvant and a copolymer of a) ethylene and b) methacrylic acid and/or acrylic acid, wherein 80 to 95 weight % of the units of said copolymer are derived from ethylene;
- coating the substrate having the liquid electrophotographic composition thereon with an overprint varnish;
- and
- subjecting the printed substrate with the overprint varnish thereon to electron beam radiation having an electron energy of 10 keV to 300 keV for a time period that branches ethylene-derived copolymer units in the liquid electrophotographic composition.
