A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

A sparkling fabric includes: a fabric substrate; and a tri-layer adhered to the fabric substrate. The tri-layer includes: an adhesive layer that adheres the tri-layer to the fabric substrate; an exposed design layer; and a metal plating layer between the exposed design layer and the adhesive layer. The tri-layer is distributed as a plurality of separable and identifiable tri-layer pieces across the fabric substrate such that the distribution of tri-layer pieces has a density on the order of 15-25 pieces per centimeter squared (pcs/cm2) and a size of a piece is less than 1 millimeter (mm).

A decoration member including: a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer. The light absorbing layer includes a copper oxynitride (Cu.sub.aO.sub.bN.sub.c).

A decoration element including a color developing layer including a light reflective layer, and a light absorbing layer provided on the light reflective layer; and an in-mold label layer provided on one surface of the color developing layer. The light absorbing layer includes a convex portion shape or concave portion shape having an asymmetric cross-section.

In a resin decorative part, a carbon decorative panel includes a clear decoration having a body transmitting light and including a carbon-toned irregular surface provided on the body and having a carbon-toned pattern formed with protrusions and depressions. The carbon-toned irregular surface has a plurality of unit patterns that constitute a weave of pseudo carbon fiber bundles presenting carbon fiber bundles in a pseudo manner, as the protrusions and depressions that form the carbon-toned pattern. The unit patterns each have a top portion positioned at the center in the extending direction of the pseudo carbon fiber bundle. A plurality of unit patterns include at least two kinds of unit patterns with different top portion inclinations, where the top portion inclination is the inclination of the long axis along the long side direction of the top portion relative to the reference line along the extending direction.

A sparkling fabric includes: a fabric substrate; and a tri-layer adhered to the fabric substrate. The tri-layer includes: an adhesive layer that adheres the tri-layer to the fabric substrate; an exposed design layer; and a metal plating layer between the exposed design layer and the adhesive layer. The tri-layer is distributed as a plurality of separable and identifiable tri-layer pieces across the fabric substrate such that the distribution of tri-layer pieces has a density on the order of 15-25 pieces per centimeter squared (pcs/cm2) and a size of a piece is less than 1 millimeter (mm).

A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion, which has a first surface having a smooth surface portion, and a second surface having plural sections, wherein each of the plural sections has a width and includes one or more convex portions which have one or more ridge lines extending in a ridge line direction. The ridge line direction of the one or more convex portions of at least one of the plural sections is different from the ridge line direction of the one or more convex portions of one or more of others of the plural sections. When the first surface of the resin molding is observed from outside, the resin molding has metallic appearance.

A decoration element including a color developing layer including a light reflective layer, and a light absorbing layer provided on the light reflective layer; and an in-mold label layer provided on one surface of the color developing layer. The light absorbing layer includes a convex portion shape or concave portion shape having an asymmetric cross-section.

Printed matter that includes a light-transmissive substrate, a laminated clear layer, and a light adjustment layer. The laminated clear layer is disposed above a main surface of the substrate, and is composed of clear element layers that are light-transmissive. The light adjustment layer has a function of adjusting an amount of light transmitted therethrough and is disposed on the laminated clear layer and/or interposed between a plurality of the clear element layers. The adjustment layer includes light reflective particles and covers a portion of a surface of a layer thereunder. Each of the light reflective particles is granular and has a light reflective surface. The light adjustment layer, in terms of surface area ratio in plan view, covers from 2% to 50% of the surface of the layer thereunder.
