Abstract
A process for manufacturing a security feature having a tactile pattern, said method including applying on a substrate a radiation-curable basecoat composition by a process selected from inkjet, offset, screen printing, flexo printing and rotogravure; at least partially or fully radiation-curing the radiation-curable basecoat composition so as to obtain a radiation-cured basecoat; applying on the radiation-cured basecoat a radiation-curable topcoat composition in a form of indicia by a process of screen printing, flexo printing or rotogravure; radiation-curing said radiation-curable topcoat composition so as to form a radiation-cured topcoat. The radiation-curable basecoat composition and/or the radiation-curable topcoat composition includes one or more machine readable feature substances independently selected from cholesteric liquid crystal pigments, luminescent compounds, infrared-absorbing compounds, magnetic compounds and mixtures thereof. The radiation-cured basecoat has a surface energy at least 15 mN/m less than the surface energy of the radiation-cured topcoat.
