Abstract

A vehicular decorative member is curved as a forward-bulging shape, and includes a transparent base, a transferred layer, a metallic layer, and a base layer. The transparent base includes a front face, and a rear face. The transparent base's rear face has an ordinary section, and a recessed section. The transferred layer, the metallic layer, and the base layer are disposed on the transparent base's rear-face side in this order. The vehicular decorative member further includes a transfer sheet turning into the transferred layer. The transfer sheet includes a support film, and an adhesive layer, a decorative layer and a release layer that are formed on the support film in this order. The transfer sheet makes the transferred layer when the support film is removed from the release layer after pressing the transfer sheet onto the transparent base's ordinary section while heating the transfer sheet.

First claim

What is claimed is:

1. A decorative member for vehicle, comprising:
a transparent base made from a resinous material and including a front face and a rear face, the rear face having an ordinary section and a recessed section dented more forward than is the ordinary section;
a transferred layer;
a metallic layer;
a base layer;
the transferred layer, the metallic layer and the base layer being disposed in this order on a rear-face side of the transparent base;
the transferred layer formed on the ordinary section in the rear face of transparent base;
the metallic layer formed on the ordinary section of the transparent base on which the transferred layer is formed and on the recessed section in the rear face of the transparent base;
the transferred layer including an adhesive layer provided on the ordinary section in the rear face of the transparent base, a decorative layer provided on the adhesive layer and a release layer provided on the decorative layer; the release layer including a first surface facing the decorative layer and a second surface facing the metallic layer at an opposite side to the first surface,
the second surface of the release layer exhibiting a surface roughness “Ra” of from 0.01 μm to 0.3 μm,
the metallic layer having a portion facing the second surface of the release layer exhibiting a surface roughness “Ra” of from 0.01 μm to 0.3 μm,
the metallic layer is a vapor deposition or sputtering film, and
the decorative layer having a surface exhibiting a surface roughness “Ra” of front 0.01 μm to 0.3 μm,
wherein the decorative member has a curved and forward-bulging shape.

2. The decorative member according to claim 1 , wherein the release layer exhibits transparency.

3. The decorative member according to claim 1 , wherein the decorative layer is a gravure printing layer.

4. The decorative member according to claim 1 , wherein the transparent base further includes a perpendicular face extending perpendicularly to the ordinary section, and surrounding a peripheral rim of the ordinary section in the rear face.

5. The decorative member according to claim 1 , wherein the release layer includes an acrylic resin.

6. An electromagnetic-wave transmission cover for transmitting a millimeter electromagnetic wave, comprising the decorative member according to claim 1 and having an overall thickness that is an integral multiple of a half of the wavelength λ of the millimeter electromagnetic wave.
