Abstract

A method for producing a decorated molded part, a decorated molded part, as well as the use of a transfer film for producing a decorated molded part includes:Producing an intermediate product in the form of a composite body by applying a transfer ply of a transfer film to a first surface of a polypropylene film, wherein the transfer ply of the transfer film has at least one decorative layer. Forming the composite body having the polymer film with applied transfer ply of the transfer film. Inserting the formed composite body into an injection mold and back injection molding and/or overmolding and/or insert molding the formed composite body with a plastic material, containing or consisting of polypropylene. Optionally, the back injection-molded and/or overmolded and/or insert-molded formed composite body is coated, in a step, over the whole surface or over part of the surface with one or more primer layers and/or one or more varnish layers.
