Problems solved by technology

However, after chrome plating, the specularity is too high and it is not in harmony with the environment in the car interior.
On the other hand, after dark plating, although there will be a sense of stability and calmness, the process is very complicated.

Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0031] The inventors of the present application have conducted repeated development and research work with the aim of realizing a metal-polished surface-like appearance with a dull luminous texture without too much gloss using a decorative film structure composed of a plurality of laminated layers. As a result, the inventors of the present application focused their research on the fact that diffuse reflection, light absorption, and one-way reflection (specular reflection) of light incident on the decorative film structure are important factors in order to realize the metal-polished surface-like appearance. superior. The inventors of the present application have also found that diffuse reflection can be reproduced by adjusting the surface roughness of the surface layer of the decorative film structure, light absorption can be reproduced by using an achromatic l...

Abstract

The invention discloses a decorative film structure (10) includes: a surface layer (1) constituted by a transparent or translucent resin layer; a metal luster layer (2) constituted by dots provided on a back surface of the surface layer (1); and an achromatic layer (3) provided on the back surface of the surface layer (1) to fill a gap between the dots. As surface roughness of a front surface of the surface layer, an Ra is 2 [mu]m or less and either an Rmax is 4 [mu]m or less or a Sm is 50 [mu]m or more. A stimulus value Y45 DEG of the metal luster layer is 10000 or more. An area of each dot when viewed from a front side of the surface layer is 10-3-105 [mu]m2. A dot area percentage per a unit area when viewed from the front side of the surface layer is 20-99%. A lightness L* of the achromatic layer is 0-80. As a result, the metal polished surface-style appearance of less strong luster and dim glowing texture is realized.

Description

technical field [0001] The technology disclosed in this specification relates to a decorative film structure and a decorative molded part that can be used for automotive interior parts and the like. Background technique [0002] There are cases where door handles and the like are required to have a metallic appearance in order to enhance the high-quality appearance of automotive interior parts such as door handles. It is known that such a metallic appearance can be obtained by performing chrome plating with excellent gloss, satin plating with silver oxide appearance, and the like. However, after chrome plating, the specularity is too high and it is not in harmony with the environment in the car interior. On the other hand, after darkening electroplating, although there will be a sense of stability and calmness, the process is very complicated. [0003] Thus, a technique is required that is easy to achieve a metallic finish style look that is not too glossy, with a dull lum...
