HeiQ grants patent license to Oberthur and VHP Security Paper for antimicrobial overprint varnishes

Materials AG, a Swiss innovation leader in antimicrobial technologies, today announced that it has entered into a License Agreement with Oberthur Fiduciaire and its subsidiary VHP Security Paper B.V. The agreement grants rights under HeiQ’s intellectual property portfolio covering the use of silver-based antimicrobial technology in overprint varnishes.
