Abstract: Provided is a decorative molded article that uniformizes the brightness of an uneven surface and inhibits whitening. The decorative molded article is provided with a protective layer having an uneven surface on an adherend, and satisfying the following requirement 1-1: A black plate is stuck to the surface of the article on the adherend side thereof via a transparent pressure-sensitive adhesive layer to prepare a sample A. A visible light inclined by 10 degrees from the normal direction of the sample A is made to run into the uneven surface, and based on the specular direction of the incident light as a reference angle, a luminous reflectance is measured every 0.2 degrees within a range of the reference angle±5.0 degrees. When the luminous reflectance at −5.0 degrees relative to the reference angle is represented by Y−5.0 and the luminous reflectance at −4.8 degrees is represented by Y−4.8, a value represented by an expression of [(Y−4.8−Y−5.0)/((Y−4.8+Y−5.0)/2)]×100 is defined as a change rate of the luminous reflectance at −5.0 degrees. When a change rate of the luminous reflectance at every measurement angle is calculated, and when an approximate straight line is drawn according to a least-square method in which the x-axis indicates the measurement angle and the y-axis indicates the change rate, the slope of the approximate straight line is −2.00 or more and −0.90 or less.

Abstract: Provided is a resin panel enabling an infrared sensor to fully function when the resin panel is applied as a protective cover to the infrared sensor. The resin panel comprises at least a core layer and has a light transmittance at a wavelength of 905 nm of 85% or more and a visible light transmittance of 20% or less.
