The invention relates to a method for producing a coated thermoplastic material in which a melt for producing the thermoplastic object is prepared, the melt is transferred into a mold and hardened therein, and the thermoplastic object thus produced is coated with another material. To ensure good adhesion of the other layer to the thermoplastic material even without an additional treatment step, it is proposed to add an adhesion promoter or a small amount of the coating material directly to the thermoplastic melt.

L'invention concerne un procédé de fabrication d'un matériau thermoplastique revêtu, dans lequel une fusion est préparée en vue de la fabrication d'un corps thermoplastique, la fusion étant réalisée dans un moule et y durcissant, et le corps thermoplastique ainsi formé est revêtu d'un autre matériau. Afin de garantir une bonne fixation de l'autre couche sur le matériau thermoplastique sans étape de traitement complémentaire, il est proposé d'ajouter un agent de fixation, ou bien une quantité moindre du matériau de revêtement, directement à la fusion thermoplastique.
