Brand protection label with a tamper evident abrasion-removable magnetic ink

摘要

The invention discloses security articles printed with an opaque or semi-transparent magnetic scratch-off removable composition printed on a substrate. The security article allows one to determine if the scratch-off media has been substantially removed prior to awarding a prize. Furthermore the invention discloses a security label having an image that is formed by applying a magnetically alignable pigment aligned by a magnetic field. A region of the magnetically formed image is more removable than another region adjacent to it, so that verification can be made of the label and its contents.
