Abstract

Disclosed is an ink comprising a transparent matrix being UV curable and heat scalable, and at least one pigment component. The ink in its UV-cured state has a peel strength in the range of about 6 to 8 N/cm, wherein this adhesiveness is achievable by means of a further lamination step under the influence of pressure and heat so that the ink acts as a hot glue. Further disclosed is a safety structure comprising a semitransparent layer being formed at least partially by the UV-cured ink, and a secure article comprising the safety structure. Further disclosed is a use of the ink for silkscreen printing.
