Bright decorative molded articles and molded articles located in the beam path of radar device
This invention provides a bright decorative molded article exhibiting a bright color, and particularly a gold color tone. Also, this invention provides a molded article located in the beam path of a radar device that allows only a small radio transmission loss. This bright decorative molded article comprises: an opaque resin substrate; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; a bright decorative layer (upper surface layer) covering the light-emitting device on the transparent resin layer; and a bright decorative layer (lower surface layer) provided on the surface of the substrate at a portion covered by the bright decorative layer (upper surface layer). Alternatively, a bright decorative molded article comprises: an opaque resin substrate; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; and a bright decorative layer (lower surface layer) covering part of the surface of the substrate.
1. A bright decorative molded article comprising: an opaque resin substrate layer; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; an upper bright decorative layer covering the light-emitting device on the transparent resin layer; and a lower bright decorative layer provided on the surface of the substrate at a portion covered by the upper bright decorative layer, all layers of said article being substantially uniformly transmissive to electromagnetic waves emitted from a radar device.
2. The bright decorative molded article according to claim 1 , wherein the upper bright decorative layer is made of at least one member selected from the group consisting of indium, tin, indium alloy, and tin alloy.
3. The bright decorative molded article according to claim 1 , wherein the lower bright decorative layer is made of at least one member selected from the group consisting of indium, tin, indium alloy, and tin alloy.
4. The bright decorative molded article according to claim 1 , wherein the light-emitting device is a light emitting diode.
5. The bright decorative molded article according to claim 4 , wherein the light emitting diode emits orange light.
6. The bright decorative molded article according to claim 1 , wherein the upper bright decorative layer and/or the lower bright decorative layer are each independently formed via vacuum vapor deposition or sputtering.
7. The bright decorative molded article according to claim 1 , wherein the upper bright decorative layer and/or the lower bright decorative layer each independently have a thickness of 0.1 nm to 1,000 nm.
8. A molded article located in a beam path of the radar device comprising the bright decorative molded article according to claim 1 .
9. A bright decorative molded article comprising: an opaque resin substrate layer; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; and a lower bright decorative layer covering part of the surface of the substrate, all layers of said article being substantially uniformly transmissive to electromagnetic waves emitted from a radar device.
10. The bright decorative molded article according to claim 9 , wherein the lower bright decorative layer is made of at least one member selected from the group consisting of indium, tin, indium alloy, and tin alloy.
11. The bright decorative molded article according to claim 9 , wherein the light-emitting device is a light emitting diode.
12. The bright decorative molded article according to claim 11 , wherein the light emitting diode emits orange light.
13. The bright decorative molded article according to claim 9 , wherein the lower bright decorative layer is formed via vacuum vapor deposition or sputtering.
14. The bright decorative molded article according to claim 9 , wherein the lower bright decorative layer has a thickness of 0.1 nm to 1,000 nm.
15. A molded article located in a beam path of the radar device comprising the bright decorative molded article according to claim 9 .
