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.

The present invention relates to a decoration sheet to be applied to an exterior material for electric home appliances or electronic devices. The decoration sheet includes a pattern layer having lenticular lenses arranged in multiple rows, wherein at least one of the multiple rows has one or more discontinuous lens sections in which the lenticular lens is not continuous, thereby reducing poor visibility and enhancing productivity; and the discontinuous lens sections can be arranged to implement a character, a pattern, or the like, thereby expressing a sense of pattern. Further, the decoration sheet has an adhesive layer formed on the other surface thereof and thus can function to prevent the scattering of a surface of glass or the like onto which the decoration sheet is attached.

A decoration element is described. The decoration element includes a light reflective layer; a light absorbing layer provided on the light reflective layer; and a color developing layer comprising a color film, wherein the color developing layer is provided: on a surface of the light reflective layer opposite to a surface of the light reflective layer facing the light absorbing layer; between the light reflective layer and the light absorbing layer; or on a surface of the light absorbing layer opposite to a surface of the light absorbing layer facing the light reflective layer.

A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion which consists essentially of a single material and which includes a first surface having a smooth surface portion, and a second surface having plural convex portions. Each of the plural convex portions includes a first inclined surface having a concavo-convex portion thereon; and a second inclined surface having a smooth surface portion. The concavo-convex portion allows at least part of light incident from the first surface to cause total reflection, diffraction and interference and to travel toward the smooth surface portion of the second inclined surface, and the smooth surface portion selectively reflects visible light in a predetermined wavelength range toward the first surface, so that when the first surface of the resin molding is observed from outside, the resin molding has a colored appearance with at least one color in addition to a metallic appearance.

An embossed sheet configuring a decorative sheet includes a sheet-shaped base that has translucency, and a plurality of reflective portions provided on one surface of the base. Each of the plurality of reflective portions has a reflective main surface that reflects incident light, and connecting surfaces that are provided between the reflective main surface and the base. Each reflective main surface is rectilinear on a first cross-section and curvilinear on a second cross-section. A gradient of a straight line at a center position of the reflective main surface that is rectilinear on the first cross-section, in relation to the one surface of the base, varies within a range of 40 degrees in each of the plurality of reflective portions. As a result, the reflective portion can reflect incident light at regular and non-regular angles.

A dial for a watch, in particular a wristwatch, having a disk with a surface on which information is arranged. Some of the information is transparent, said transparent information being visible or at least nearly invisible according to the viewing angle. The dial of the invention has a simple and yet sophisticated look. Furthermore, the dial allows a watchmaker's name to be shown without same significantly impacting the look.

An image displaying device includes a background layer and a display layer. The display layer includes an inner surface and an outer surface. The inner surface is substantially smooth, and the outer surface includes a plurality of raised areas and recessed areas. The display layer has a first zone with a first thickness measured between the inner surface and a raised area and a second zone with a second thickness measured between the inner surface and a recessed area. The display layer also includes a coloring agent having a higher concentration in the first zone as compared to the second zone. The display layer has increased light transmissivity through the recessed areas and decreased light transmissivity through the raised areas such that a contrast of light transmissivity between the raised and recessed areas generates an image.

A decoration method of a printed matter includes: forming a printed layer on a surface of a sheet or of a mounting paper with a transparent varnish, printing a predetermined pattern on the surface of the printed layer by an ink or by a resin which are capable of being adhered to the printed layer; and pressing a metal foil onto the pattern printed by the ink or the resin with an adhesive agent. The adhesive agent does not adhere to the printed layer but adheres to the pattern. As a result, the metal foil 6 is printed only to the pattern.
