The method comprises injecting molten polycarbonate material into amould where is positioned a transparent film imprinted with the design. The filmbonds with the polycarbonate material to form a laminated structure. The ink impression is applied on a surface of the film that bonds with the polycarbonate so the ink is embedded in the laminated structure and it is thus protected from scratches and contact by foods.

Méthode de fabrication d'articles de vaisselle comme des tasses ou des plats décorés d'un dessin multicouleurs intégré à la surface de la pièce qui entre en contact avec de la nourriture. L'article de vaisselle peut être utilisé au four à micro-ondes sans que cela entraîne la détérioration du dessin multicouleurs, c'est à-dire décoloration, formation de soufflures ou provoque l'émission de fumées nuisibles ou toxiques. La méthode consiste à injecter un matériau de polycarbonate fondu dans un moule où est placée une pellicule transparente sur laquelle le dessin se trouve imprimé. La pellicule adhère au polycarbonate pour former une structure laminée. L'encre d'impression est appliquée sur la surface de la pellicule qui adhère au polycarbonate de sorte que l'encre est incrustée dans la structure laminée et qu'elle est ainsi protégée des égratignures et n'entre pas en contact avec les aliments. L'invention vise aussi un nouvel article de vaisselle.
