An electronic device may include electrical components and other components mounted within an interior of a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer may be provided with regions having different appearances. The regions may be textured, may have coatings such as thin-film interference filter coatings formed from stacks of dielectric material having alternating indices of refraction, may have metal coating layers, and/or may have ink coating layers. Textured surfaces may be formed on thin glass layers and polymer films that are coupled to the glass layer. A glass layer may be formed from a pair of coupled glass layers. The coupled layers may have one or more recesses or other structures to visually distinguish different regions of the glass layer.

A label for a battery includes a base material sheet; and a phosphorescent print layer famed by applying a phosphorescent material onto a surface of the base material so as to display information concerning the battery. The phosphorescent material is provided in a region on the surface of the base material where the information for identifying the battery is displayed. The information for identifying the battery is information indicating a standard of the battery, for example. The information concerning identification of the battery is information indicating a polarity of the battery.

An apparatus and a corresponding method that includes providing a color-code device having a first pre-cut piece of tape having an adhesive surface covered by a release liner. wherein the first pre-cut piece of tape has a starting end and a finish end, and wherein the finish end has a diagonal edge at an acute angle to a lengthwise edge of the piece of tape; removing a first piece, of the release liner; and beginning with the start end, wrapping the first piece of tape around a communications cable while removing a remaining piece of the release liner. In some embodiments, the device is supplied on a roll, or Z-folded flat pack, or as one of a plurality of individually supplied tape pieces each on release-paper substrate of like devices, each precut to a length and finishing-edge angle to prevent water buildup on a cable wrapped with the device.

The present invention relates to a web authentication hologram label and a method for manufacturing the same, and more particularly, to a web authentication hologram label and a method for manufacturing the same which in forming a web authentication label for identifying a genuine article, enable enhancement of a forgery (and falsification) preventing function as well as duplicate authentication for confirming whether or not an article is genuine to be substantially impossible by means of adopting one-time authentication.

An indicator tag and a method for fabricating the same are disclosed. For example, the indicator tag includes a three-dimensional mesh comprising a plurality of pores, wherein the three-dimensional mesh is printed with a water soluble and ultra-violet (UV) light curable ink, a container enclosing the three-dimensional mesh, a membrane coupled to the three-dimensional mesh, and a dye dispensed on top of the membrane, wherein the three-dimensional mesh interacts with the dye when in contact with the dye to provide an indication.

A cutting plotter film with anti-counterfeit effect includes: a heat-resistant layer; a stripe-embossed layer having releasing property and bonded on the heat-resistant layer, the stripe-embossed layer being formed with a stripe-embossed surface; a character film layer disposed on the stripe-embossed surface of the stripe-embossed layer, having a contact surface in contact with the stripe-embossed surface, the contact surface being formed with anti-counterfeit stripes; and a heat bonding layer disposed on the character film layer. Figures/characters are cut/engraved on the character film layer and the heat bonding layer. The cutting plotter film is placed on a product and heated to transfer and adhere the figures/characters onto the product.

A dielectric layer comprising an embossed surface and a flat surface which is located at a side opposite to the embossed surface is provided. The plane that approximates the flat surface is the X-Y plane, and the normal direction to the X-Y plane is the Z direction. The embossed surface has inclined surfaces that are inclined with respect to the Z direction, and the inclined surfaces reflect incident light incident on the dielectric layer and emerge reflected light. The elevation angle, which is an angle between the inclined surface and the X-Y plane, is . The refractive index of the dielectric layer is n. These values satisfy Formula (1): sin (1/n)<sin 2.

The present disclosure provides a laser-markable article with customized watermarks and a preparation method thereof. The laser-markable article with customized watermarks comprises a surface layer (1) containing a first coloring agent, a bottom layer (2) containing a second coloring agent, an adhesive layer (3), and an optional release layer (4) arranged consecutively in a stack, and further comprises customized watermarks (5,5) arranged in the surface layer (1), wherein the customized watermarks (5,5) are comprised of a plurality of watermark units spaced apart from one another and regularly distributed in the surface layer (1), and each watermark unit is comprised of a laser-etched pattern with an etch depth of 2.5 to 25 micrometers.
