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 decorative product includes a decorative layer containing nickel, chromium, and molybdenum as constituent components. The molybdenum content in the decorative layer is 50 atm % or less. The total content of nickel, chromium, and molybdenum in the decorative layer is 95 atm % or more.

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 a substrate provided on a surface of the color developing layer. The substrate comprises a pattern layer, and the light absorbing layer comprises an aluminum oxynitride (Al.sub.aO.sub.bN.sub.c).

Provided is a decorative sheet (100) including: a transmissive substrate (10) which is sheet-like or plate-like; a light reflective projection portion (20) formed over the light transmissive substrate (10); and a black layer (30) formed over the light reflective projection portion (20), in which an average height of the light reflective projection portions (20) is 1 to 200 pm, and the black layer (30) is formed by using a black ink satisfying conditions below.

In a resin decorative part, a clear decoration has a body transmitting light and includes a carbon-toned surface provided on the opposite side to the viewer side of the body and having a carbon-toned pattern. The carbon color layer is colored in a carbon color, is laminated on the carbon-toned surface, and has a reflective surface reflecting light transmitted through the clear decoration. The carbon-toned pattern is formed with a plurality of pseudo carbon fiber bundles presenting carbon fiber bundles formed by bundling carbon fibers in a pseudo manner. The pseudo carbon fiber bundle has a plurality of linear grooves that constitute pseudo carbon fibers presenting carbon fibers in a pseudo manner. The carbon-toned surface includes a pseudo carbon fiber bundle in which the length in the extending direction of each linear groove and the depth of the linear groove vary in a predetermined range.

Provided are a decorative glass panel having a three-dimensional metal design and a manufacturing method for the decorative glass panel, the method exhibiting enhanced productivity. A decorative glass panel 10 includes: a glass substrate 15; an adhesive layer 11 formed on the glass substrate 15; a non-uniform pattern layer 12 formed on the adhesive layer 11; and a vapor-deposited metal layer 13 formed on the non-uniform pattern layer 12. In the glass substrate 15, a section that is a portion of a back surface of the glass substrate 15 and that is bent from a flat surface section 30 to an upright section 31 forms a curved surface 32. The non-uniform pattern layer 12 has, in a surface facing the vapor-deposited metal layer 13, which is a top surface thereof, a non-uniform pattern formed by depressions 40 and protrusions 41.

Provided is a decorative sheet (100) including: a transmissive substrate (10) which is sheet-like or plate-like; a light reflective projection portion (20) formed over the light transmissive substrate (10); and a black layer (30) formed over the light reflective projection portion (20), in which an average height of the light reflective projection portions (20) is 1 to 200 m, and the black layer (30) is formed by using a black ink satisfying conditions below.

[Conditions]

In a dried coated film which is formed using the black ink by a film forming method below, a gloss value of a surface of the dried coated film, which is measured at a measurement angle of 60 in accordance with JIS Z 8741 (1997) is equal to or more than 80 and a lightness L* value of the surface of the dried coated film in the CIE 1976 (L*, a*, and b*) color system, which is measured by an SCE method is equal to or less than 10.

Film forming method of dried coated film: The black ink is applied to a polyethylene terephthalate film by using a bar coater having a wire diameter of 6 mil by pulling at a moving speed of 50 mm/sec and then dried at 80 C. for 15 minutes to obtain a dried coated film.

The present disclosure relates to a decoration element comprising a light reflective layer; and a light absorbing layer provided on the light reflective layer, wherein the light reflective layer has surface resistance of 20 ohm/square or less.
