The present invention provides a method for producing a light guide plate including a light-diffusing surface. The method includes (1) applying a protonic polar solvent to a surface of a polycarbonate substrate, and (2) heating the polycarbonate substrate in a water-containing environment to cause precipitation of bisphenol A particles each having a particle size of 10 m or smaller on the surface of the polycarbonate substrate.

A vehicle light assembly includes a housing. A light source is positioned within the housing. A lens is coupled with the housing. The lens defines a first surface and a second surface. A plurality of optical gratings is integrally defined in at least one of the first and second surfaces. The plurality of optical gratings is arranged in a spaced apart configuration.

This invention relates to the development of a multi-layer PC polar laminate and its cut and form process. The laminate displays increased adhesion between a PC film layer and an adjacent film layer. As a result of the increased adhesion, less adhesive may be applied between laminate layers, which positively affects PC cracking and mold cavity contamination.

This eyeglass lens is outstanding in anti-crazing properties, impact resistance properties, and adhesion. The present invention comprises: a lens substrate; a primer layer disposed on the lens substrate; and at least one layer that is disposed on the primer layer and that is selected from the group consisting of a hard-coat layer and a reflection-preventing layer. The primer layer contains a polycarbonate-based polyurethane resin and inorganic oxide particles. The tensile strength of the polycarbonate-based polyurethane resin is over 40 N/mm.sup.2. The expansion rate of the polycarbonate-based polyurethane resin is at least 300%, and the inorganic oxide particle content is 10-40% by volume with respect to the total volume of the primer layer.

The present disclosure relates to a composite article that may include a plastic component, and a silicone component bonded the plastic component. The plastic component and the silicone component may be bonded at an intersecting region between a first surface of the plastic component and a first surface of the silicone component. The intersecting region may include at least one of an acetone content of not greater than about 0.2 ppm, an MEK content of not greater than about 0.2 ppm, or a trimethylsilanol content of not greater than about 0.2 ppm.

A display device includes a window member and a display module coupled to the window member. The window member includes a first resin layer and a second resin layer. The first resin layer is on the display module and has a first elongation, a first thickness, and a first hardness. The second resin layer is on the display module and the first resin layer and has a second elongation smaller than the first elongation, a second thickness greater than the first thickness, and a second hardness greater than the first hardness.

A protective film-attached functional sheet includes a protective film bonded to a functional sheet including aromatic polycarbonate sheets and a functional layer sandwiched between the aromatic polycarbonate sheets, the functional layer being a polyvinyl alcohol polarizing film layer, a photochromic layer, or a combination. The protective film is a polyolefin resin film that includes at least two layers: a base layer formed of a polypropylene having a melting point equal to or higher than a glass transition temperature of the aromatic polycarbonate and an adhesive layer on one surface of the base layer and being a resin composition containing a polyolefin rubber and a polyolefin having a melting point lower than the glass transition temperature but equal to or higher than 15 C. lower than the glass transition temperature; or at least three layers: the aforementioned two layers and an intermediate layer between the base layer and the adhesive layer.

A method for installing an advertising unit on a ground surface includes cleaning an installation area located at the ground surface, applying an adhesive at the installation area, depositing the advertising unit at the installation area atop the adhesive, and curing the adhesive. In some embodiments, the advertising unit comprises a back unit having a track which accommodates a cover in a sliding fashion. In some embodiments, the installation area may be excavated to render an upper surface of the advertising unit flush with the surface of the ground when deposited.

The invention relates to a film body, a method for the back-injection molding of a film body and a back-injection molding tool therefor. In particular, the invention relates to a method for the back-injection molding of layer electrodes (1) for producing touch-sensitive sensors for example for touch screens. Parts of the layer electrode (1), which after the back-injection molding should still be able to move freely, are covered by a sacrificial film (3) before and during the back-injection molding.

A method of making an iridescent, vehicular trim assembly is provided that includes: molding a polymeric base comprising an exterior surface; and over-molding an element over at least a portion of the exterior surface. The element comprises a polymeric, translucent material and an exterior surface with an integral diffraction grating having a thickness from 250 to 1000 nm and a period from 50 nanometers to 5 microns. Further, the molding can be conducted such that the polymeric base is molded with a tint. The method can also include forming a plated region over the exterior surface of the base. In addition, the method can also include cleaning the plated region with a plasma-etching process before the over-molding.
