Abstract
A decorative panel includes a transparent resin layer, a light-transmissive substrate configured to be disposed on a back side of the transparent resin layer and configured to visually express a three-dimensional pattern created by an uneven surface of the light-transmissive substrate, and a semi-transmissive layer configured to be disposed on a back side of the light-transmissive substrate and having a contour corresponding to the uneven surface of the light-transmissive substrate.
Claims5
A decorative panel, comprising:
- a transparent resin layer;
- a light-transmissive substrate configured to be disposed on a back side of the transparent resin layer and configured to visually express a three-dimensional pattern created by an uneven surface of the light-transmissive substrate;
- and
- a semi-transmissive layer configured to be disposed on a back side of the light-transmissive substrate and having a contour corresponding to the uneven surface of the light-transmissive substrate.

A manufacturing method, comprising:
- forming a semi-transmissive layer having a uniform transmittance and a uniform film thickness by screen-printing a semi-transmissive ink on a back side of the light-transmissive substrate;
- forming, on the light-transmissive substrate on which the semi-transmissive layer is formed, an uneven surface that is perceived as a three-dimensional pattern;
- and
- performing insert molding to form a transparent resin layer on a front surface of the light-transmissive substrate on which the uneven surface is formed.
