Laser-inscribable film, comprises (i) a contrast layer based on a hardened acrylate lacquer composition, and (ii) an engraving layer arranged above the contrast layer, where the hardened acrylic lacquer composition comprises (in wt.%): a trifunctional oligomer (a) (30-80), a trifunctional monomer (b) (0-20), a difunctional monomer (c) (1-30), and a coloring pigment (2-40). Independent claims are also included for: (1) the acrylate lacquer composition comprising the above mentioned hardened composition; and (2) manufacturing a laser-inscribable film, comprising (i) providing a supporting film, (ii) applying the engraving layer on the supporting film, (ii) applying the acrylate lacquer composition on the engraving layer, (iv) hardening the acrylate lacquer composition, to obtain the contrast layer, (v) optionally applying an adhesive composition on the contrast layer and covering the adhesive composition with a release paper or release-liner, and (vi) removing the supporting film. |
