Abstract
A method of making a piece of plastic that is painted. The method consists in depositing a “peel-off” film inside a mold defining the shape of the piece, which film is suitable for being separated easily from the support to which it is fixed, in making the piece by molding over the film, in painting the piece in full, and in removing the film so as to uncover the non-painted portion of the piece.
