Laser-inscribable film, comprising a contrast layer based on a cured acrylate coating composition and, arranged above the contrast layer, an engraving layer, where the cured acrylate coating composition is based on a composition comprising from 30 to 80% by weight of a trifunctional oligomer A, from 0 to 20% by weight of a trifunctional monomer B, from 1 to 30% by weight of a difunctional monomer C, and from 2 to 40% by weight of a colorant pigment.

Heat-resistant laser-inscribable film

A method for producing a multi-layered film wherein an engraving layer is partially printed onto a support film. Said engraving layer may be made of a UV-cured printing ink and a cover layer is applied to the entire surface above the partial engraving layer, optionally, directly to the partial engraving layer. The cover layer may be made of a UV-curable printing ink and may be printed over the engraving layer. A film produced by such method is also disclosed.

Method for producing a multi-layered film

The invention relates to an adhesive according to a conventional formulation, comprising additives capable of binding metal ions in the sense of chemical interactions, electrochemical interactions and/or physical interactions.
