1. A method for producing a decorative part for a vehicle interior, wherein:
the decorative part comprises a substrate and a decorative layer applied to the substrate, wherein a front side of the decorative layer opposite the substrate forms a visible side of the decorative part, and
the method comprises the steps of:
a) providing a substrate film,
b) forming a composite layer by applying a decorative ply to a first side of the substrate film,
c) applying micro-perforation of the decorative ply in one or more regions or over the entire surface, wherein the micro-perforation of the decorative ply introduces a plurality of through-holes on the decorative ply by removing the decorative ply in the region of the through-holes, whereby the through-hole have diameters that are selected such that the through-holes are not visible to an observer on the visible side of the decorative part when viewed without aids and without back-lighting;
d) inserting or drawing in the composite layer made of substrate film and micro-perforated decorative ply into a cavity of an injection mold in such a way that, when plastics material is injected into the cavity, the decorative ply of the composite layer is back-injected and a second side of the substrate film opposite the first side is pressed against a wall of the cavity,
e) closing the cavity and injecting plastics material into the cavity to form the substrate of the decorative part, the decorative ply being back-injected and the decorative ply being applied to a surface of the substrate facing the decorative ply during substrate formation in the cavity, thereby forming the decorative layer of the decorative part,
f) opening the cavity and removing or ejecting the decorative part.
