Abstract

A large number of small reflection portions are continuously formed over a back face of a base member opposite the light impinging side, in an arbitrary arrangement. The small reflection portions are each formed to have a boundary surface for reflection, interference, and diffraction of incident light impinging onto the base member, to thereby produce random changes in the brightness of reflection light over the entirety of the decoration panel. A reflection layer is formed on the boundary surfaces of the small reflection portions such that the boundary surfaces function as mirror surfaces and reflect light propagating through the base member toward the front face of the base member.

Description

technical field [0001] The present invention relates to a decorative panel for molded plastic products of vehicles, furniture, cellular phones, and the like. Background technique [0002] A known example of a conventional decorative panel is an ornament (decorative panel for an automobile), which is attached to the rear end of a passenger car, between the rear combination lamps (see Japanese Patent Application Laid-Open (kokai) No. H04-78632). [0003] Such a decorative panel includes a cover formed of a transparent synthetic resin material such as acrylic, and a mounting base member for mounting the cover to an automobile body. The cover has a smooth outer surface and an embossed inner surface facing the mounting base member. Fish-eye portions each having a concave hemispherical shape are continuously formed on the surface of the mounting base member facing the inner surface of the cover, and silver metallic paint is applied on the fish-eye portions, thereby forming a meta...
