Visible part having a layer structure for an operating part or a decorative trim with better protection as a result of a protective paint coating

A visible part for an operating part or decorative panel, in particularly for use in a motor vehicle, comprising a layer structure with the following layer sequence of layers while forming interfaces:

• a lower substrate layer;
• a decorative layer having a thickness;
• and
• an upper cover layer, wherein the upper cover layer is any one of:
• translucent and transparent;
• wherein the layer structure forms an end face into which an access to at least one interface enters, and wherein the lower substrate layer forms a projection with respect to the decorative layer and the upper cover layer of the layer structure;
• wherein the visible part furthermore has an outer transparent protective paint layer, which covers the upper cover layer and the end face and which, if the visible part is attached as intended, forms a top surface facing towards an observer and covers the access;
• wherein the entirety of at least the end face of the layer structure is covered by the outer transparent protective paint layer to seal the access in at least one of:
• an air-tight and a liquid-tight manner;
• wherein the outer transparent protective paint layer forms a wedge covering the access and resting on the projection;
• and
• wherein a width size of the projection is within a range defined as follows:
• half the thickness of the decorative layer<width size of the projection<twice the thickness of the decorative layer.
