The present invention discloses an optical film and a cover plate for an electronic device. The optical film comprises: a support; a micro/nano-structure layer which is formed by providing a groove on a surface of the support, which groove forms a micro/nano-structure and is provided with a filler; wherein the micro/nanostructure layer has a visual gradient in at least one direction. The present invention provides an optical film, which realizes a visual change or a gradient effect, by adjusting the area ratio of the micro/nano-structure, the depth of the groove, the period of the micro/nano-structure or the density of the micro/nano-structure, and produces a decorative or practical effect. It plays an aesthetic role when used in the casing of an electronic device, and it can shade light but not block the sight line when used in buildings or automotive glass. Furthermore, no black spots will appear with this structure, and it is visually more artistic.

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (“UV”) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.

A method of creating a selectively plated three-dimensional thermoplastic part. The method includes the steps of: a) providing a film of uncured polycarbonate film having a hardcoated layer on a first surface thereof; b) selectively catalyzing the polycarbonate film by depositing a catalyst in a desired pattern on the first surface of the polycarbonate film; c) thermoforming the polycarbonate film to form a three-dimensional polycarbonate film; d) UV-curing the hardcoated polycarbonate film by irradiating the film with UV rays; e) molding the hardcoated polycarbonate film to produce a three-dimensional molded part comprising the hardcoated polycarbonate film; f) activating the selectively catalyzed hardcoated polycarbonate film; and g) plating a metal layer on the catalyzed portions of the hardcoated polycarbonate film, wherein the plated metal only deposits on the catalyzed portions of the hardcoated polycarbonate film.

An optical device that produces flicker-like optical effects is provided. The inventive device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).

A lighting element configured to be mounted on a mounting surface. The lighting element comprises a base member, at least one forward member, and at least one base-illuminating light source. The base member is adjacent the mounting surface when mounted and has a base member front surface positioned to face away from the mounting surface when mounted. The at least one forward member has a front surface and a rear surface opposite the front surface. The rear surface is spaced from and in face-to-face relationship with the base member front surface. The at least one base-illuminating light source is adjacent the forward member rear surface, is adapted to emit light, and is positioned to project light toward the base member front surface and such that no portion of the at least one base-illuminating light source extends beyond the forward member front surface nor rearward beyond the forward member rear surface.

Embodiments relate to a decorative sheet having a hairline design and including successively, from a front surface side thereof, (A) a layer of a transparent resin film and (B) a layer of an ink paint film containing high brightness pigment. A plurality of linear hairline grooves is provided on a surface of the transparent resin film on a side thereof facing (B) the layer of the ink paint film containing the high brightness pigment. The decorative sheet has a surface resistivity of 110.sup.5 or more on a rear surface side thereof. When the decorative sheet is placed on a dirt comparison chart created by the NPB in an environment of an illuminance of 600 lux, and is illuminated from below the chart at an illuminance of 17000 lux, a figure having a size of 5 mm.sup.2 on the chart can be visually discriminated. When the decorative sheet is placed on a gray scale for soiling stipulated in JIS L0805:2005 in an environment of an illuminance of 500 lux, the color difference between color chips numbers 4 and 5 cannot be visually discriminated.

A method for surface decoration of articles comprises the following steps A), B) and C). Step A) comprises applying a base layer to the surface of a main body. The base layer comprises at least one photoluminescent additive. Step B) comprises applying on the base layer a metallization layer configured to make at least partially visible the photoluminescence of said base layer. In particular, step B) comprises a process of deposition of metal particles on the base layer. Step C) comprises applying a transparent coating layer on the base and metallization layers. The above-mentioned method allows to obtain an article with a metallic surface finishing having a luminescence effect which can be perceived especially in low light conditions or under the effect of ultraviolet light.
