AI Technical Summary

Technical Problem

Existing decorative panels are difficult to maintain the depth effect of the three-dimensional surface visually, and it is difficult to strike a balance between durability and weight saving. In particular, there is a risk of wear and injury when used in a motor vehicle.

Method used

By setting a three-dimensional surface profile on a transparent or translucent carrier and forming an effect layer on the visible surface or back side of the carrier using a printing step, the transmittance and color value of the effect layer are related to the height coordinate to produce an improved optical depth effect, while reducing the average roughness depth of the surface profile and lowering the material strength requirement of the carrier.

Benefits of technology

The optical depth effect is maintained while reducing the material strength and weight of the decorative panel, lowering the risk of breakage and damage to the carrier, and meeting the durability and aesthetic requirements in motor vehicles.

Abstract

The invention relates to a decorative panel (1) comprising a transparent or translucent carrier (2) which, when installed as specified, defines a visible surface (5) facing an observer and a back surface (6) facing away from the observer, wherein one of the multiple surfaces of the visible surface (5) and the back surface (6) forms a three-dimensional surface profile (K) which can be described relative to a reference plane (E) by means of a height coordinate (h); and at least one effect layer (3) which is applied to the back surface (6) or the visible surface (5) of the carrier (2) and is formed such that the following applies to multiple positions of the effect layer (3): the local transmittance and / or local color value at the corresponding position of the effect layer (3) is related to the height coordinate (h) of the following point of the surface profile (K), the vertical projection of which onto the reference plane (E) coincides with the vertical projection of the corresponding position of the effect layer (3) onto the reference plane (E); and a related manufacturing method.
