A decorative member includes a transparent layer, a first decorated layer, and a second decorated layer. The first decorated layer is disposed on the transparent layer's rear surface. The second decorated layer is disposed on the transparent layer's rear surface. The transparent layer's rear surface has an irregular configuration that includes indented portions and indent-free portions. The indented portions dent toward the transparent layer's front surface. The indent-free portions protrude toward the transparent layer's rear surface. The first decorated layer is disposed directly on the rear surface of the transparent layer partially. The second decorated layer is made of a film that includes resin, and is laminated on the first decorated layer and on the transparent layer's rear surface entirely.

A resin product (e.g., a millimeter-wave radar device cover) comprises a plate-like resin substrate, a base film formed on the resin substrate, and a metallic gloss film having a discontinuous structure formed on the base film, a top coat, a block coat, or the like being formed as a protective film on the metal film. The metal film contains a first film having a discontinuous structure obtainable by vacuum deposition of a first metal, a modified surface obtainable by modification of the surface of the first film by bringing the surface into contact with air, and a second film having a discontinuous structure obtainable by vacuum deposition of a second metal on the modified surface.

Resin product

The present invention provides a metallic coating having a sheen and having a discontinuous structure at high productivity and low cost by using sputtering. A resin product includes a resin base material, and a metallic coating having a sheen and a discontinuous structure that is deposited on the resin base material so as to include a portion in which a high-formation metal that relatively readily forms a discontinuous structure when using vacuum vapor deposition is sputtered, and thereafter, a low-formation metal that does not relatively readily form a discontinuous structure when using vacuum vapor deposition is sputtered. The high-formation metal and the low-formation metal are selected from at least two species of metals whose crystal structures are identical and whose lattice constant difference is within 10%.

A radiator grille, or ornament, includes a base material which transmits visible light and is made of an acrylic resin, a first ornamental layer coating the front surface of the base material, and a second ornamental layer coating the rear surface of the base material. The first and second ornamental layers each transmit visible light and have a thickness that is less than the wavelength of the visible light. It is preferred that the first ornamental layer and the second ornamental layer differ from each other in at least one of material, number of layers, thickness, refractive index of visible light, reflectance of visible light, absorptivity of visible light, and transmittance of visible light. The first ornamental layer is a hard coating layer, and the second ornamental layer is a hard coating layer or vapor deposition layer.

Ornament

A radar device is placed rearward of a vehicle decorative component in a vehicle. The decorative component is located in the path of radar waves emitted from the radar device, and has a two-layer structure with a back layer and a protective layer. The protective layer is made of a transparent resin material, and the back surface of the protective layer contacts the front surface of the back layer. The back layer is made of a resin material. The front surface of the back layer includes a front contact surface on which ground pattern is formed. The protective layer and the back layer have the same refractive index. Thus, the decorative component has an improved transparency of radar waves.

Vehicle decorative component

A radar device for a mobile body, such as a vehicle, having a high degree of installation freedom. The radar device comprises a sensor body transmitting and receiving electromagnetic waves, and path changing means placed in an electromagnetic wave path through which the electromagnetic waves pass and changing the propagation direction of the electromagnetic waves by refraction and/or reflection. Even when the installation site of the sensor body is restricted by requirements on a mobile body on which this radar device is to be mounted, the sensor body can be installed at the restricted site by changing the propagation direction of electromagnetic waves appropriately, while maintaining the functions of the sensor body appropriately.

The wave-transmitting cover comprises a transparent resin layer, a base layer and a decorative layer, and the decorative layer contains a lustered piece. The method for producing it comprises a film-forming step of forming a film that has a print face and a deposition design face formed thereon, a shaping step of shaping the film, a first molding step of molding one of a transparent resin layer or a base layer thereon to give a first molded part, and a second molding step of forming the other of the transparent resin layer or the base layer on a surface of the first molded part where the film is provided.

An interior finish member having a door for an air bag includes a main body and a cover. The main body surrounds the periphery of the cover, and the main body and the cover form a continuous surface. The cover covers a folded air bag. The cover includes: a door, which covers the folded air bag. A breakable portion is defined by a recessed periphery of the door and is relatively thin. A hinge connects the door with the main body and provides a pivot around which the door pivots under a force of an expanding air bag. The main body is made of thermoplastic resin, and the cover is made of thermoplastic elastomer. The main body and the cover portion can be integrally formed.

Wave-transmitting cover, and method for producing it

A vehicle exterior component includes an unwoven fabric having a noise absorbing function and an additional layer attached to the unwoven fabric. The unwoven fabric includes main fibers and binder fibers. The melting point of the binder fibers is lower than that of the main fibers. The unwoven fabric further includes a mesh structure in which the main fibers and the binder fibers are intertwined and welded to each other. The mesh structure is obtained by pressing a fiber web in which the main fibers and the binder fibers are intertwined. The unwoven fabric is formed into a predetermined outer shape. The additional layer has a function other than the noise absorbing function.

The object of the invention is to provide a method for molding a resin-molded article having an excellent surface appearance without any resin-intrusion part on the front surface of a skin thereof. In the invention, the skin is placed on a part of a inner wall of a mold and then injecting a synthetic resin into a cavity of the mold to effect an integral molding of a resin-molded article having the skin on a part thereof, wherein a mold having a first gate on a first inner wall part located on the part other than the back surface of the skin placed on the inner wall of said mold and a second gate on a second inner wall part which faces the back surface of the skin placed on the inner wall is employed; and wherein the synthetic resin is first injected from said first gate until the tip portion of the synthetic resin comes close to the edge of said skin, and then the synthetic resin is injected from the second gate.
