Decorated-part having a fine decoration using a laser processed groove

A decorated-part of which a fine decoration is provided on a surface of the decorated-part by a laser-processed groove, the decorated part comprising:

• a resin base-material;
• the first base coat-layer formed on a surface of the resin base-material;
• at least one second base coat-layer formed on a surface of the first base coat-layer;
• and
• a surface coat-layer formed on the second base coat-layer, a thickness of the surface coat-layer being greater than a thickness of the second base coat-layer;
• and
• further characterized in comprising a first laser-processed groove that goes through the surface coat-layer and partially exposes the second base coat-layer but does not expose the first base coat-layer, and a second laser-processed groove, which has a groove depth less than a groove depth of the first laser-processed groove, the second laser-processed groove not penetrating the surface coat-layer,
• the surface coat-layer, including the second laser-processed groove, being a single layer colored in black, an entire top surface of the surface coat-layer being totally visible;
• the first base coat-layer being colored in white, invisible, and having no surface design;
• and
• the second base coat-layer being colored in a chromatic color brighter than the color of the surface coat-layer, a top surface of the second base coat layer being partially visible;
• wherein a roughness (Ra) of the exposed area, which is at a bottom of the first laser-processed groove of the second base coat-layer, is 2 μm or less,
• wherein the surface coat layer further comprises:
• a plurality of first drawn patterns of rectangular shape;
• and
• a plurality of second drawn patterns of rectangular shape;
• each of the first drawn patterns including the second laser processed grooves, the second laser processed grooves drawn in parallel and extending obliquely upward to the right in plan view for each of the first drawn patterns;
• each of the second drawn patterns including the second laser processed grooves, the second laser processed grooves drawn in parallel and extending obliquely upward to the left in plan view for each of the second drawn patterns;
• the first and second drawn patterns adjacent to each other on the surface coat-layer.
