Patent number: 11392053Abstract: 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.Type: GrantFiled: April 30, 2019Date of Patent: July 19, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Boris Kaziev, Dani Tulchinski, Liora Braun, Einat Glick, Yair Gellis, Debby Margoy

Patent number: 11143977Abstract: Herein is described a method of producing a printed label. The method may comprise: a. providing a label substrate having a first surface and a second surface, wherein the first and second surfaces form opposing surfaces of the label substrate; b. applying a primer comprising a cross-linkable primer resin onto the first surface of a label substrate to form a primer layer; c. electrophotographically printing onto the primer layer an electrostatic ink composition comprising a cross-linkable thermoplastic resin to form a printed layer; d. applying a cross-linking composition comprising a cross-linking agent to the printed layer, wherein the cross-linking agent penetrates into the electrostatic ink composition and the primer layer; and e. activating the cross-linking agent wherein an adhesive is present on the second surface of the label substrate in step a or applied to the second surface of the label substrate at any point in the method after step a. Printed labels are also described herein.Type: GrantFiled: July 21, 2016Date of Patent: October 12, 2021Assignee: HP Indigo B.V.Inventors: Asaf Salant, Dani Tulchinski, Inna Tzomik, Daniel Skvirsky, Tony Azzam
