Various processes for creating mirrored features are discussed herein as well as devices that include the mirrored features. One embodiment includes a button having a transparent layer and an opaque layer coupled to the transparent layer. A portion of the transparent layer extends through the opaque layer so that the portion of the transparent layer is flush with a back surface of the opaque layer and generally has a shape of a desired feature. The button also includes a reflective object positioned so that it may be seen through the transparent layer.

Provided herein is a method of making a clear or translucent object by additive manufacturing, comprising (a) providing a clear or translucent light polymerizable resin, the resin comprising: (i) light-polymerizable monomers, prepolymers, or a combination thereof; (ii) a photoinitiator; and (iii) a polysubstituted linear polyacene ultraviolet light absorbing compound which compound is polysubstituted with bromo, chloro, —Se—R′, —S—R′ or combinations thereof, where each R′ is independently selected from alkyl, aryl, and arylalkyl; and then (b) producing by stereolithography with ultraviolet light a clear or translucent object from said light polymerizable resin.

Multilayer polymer sheets are provided, as well as related methods, systems, and appliances.

A vehicle display device decorative part and a vehicle display device include a first area provided in the vehicle display device that displays information regarding a vehicle, and having a first pattern formed of a plurality of first grooves, and a second area provided to be included in the first area, and having a second pattern formed of a plurality of second grooves. As a result, the vehicle display device decorative part and the vehicle display device exhibits an effect to realize new and fresh visual effects due to a synergistic effect by a combination of the first pattern formed in the first area and the second pattern formed in the second area included in the first area.

A transparent multilayer coextruded heat shrinkable barrier film is useful for high-value packaging applications such as food and medical device packaging. The transparent multilayer coextruded heat shrinkable barrier film includes first and second outer layers formed using a transparent polyester or polyester copolymer; an inner nanolayer sequence including a plurality of nanolayers a) including ethylene vinyl alcohol, alternating with nanolayers b) including at least one of ethylene ethyl acrylate, low density polyethylene and linear low density polyethylene, each of the nanolayers b) having a degree of crystallinity less than about 45%; and adhesive layers between each of the two outer layers and the inner nanolayer sequence. The film has a light transmittance of at least about 80% and a heat shrunk of at least about ten percent in at least one direction.

A method for fabricating custom surface reflectance and spatially-varying bi-directional reflectance distribution functions (BDRFs or svBRDFs). The 3D printing method optimizes micro-geometry to produce a normal distribution function (NDF) that can be printed on surfaces with a 3D printer. Particularly, the method involves optimizing the micro-geometry for a wide range of analytic NDFs and simulating the effective reflectance of the resulting surface. Using the results of the simulation, the appearance of an input svBRDF can be reproduced. To this end, the micro-geometry is optimized in a data-driven fashion and distributed on the surface of the printed object. The methods were demonstrated to allow 3D printing svBRDF on planar samples with current 3D printing technology even with a limited set of printing materials, and the described methods have been shown to be naturally extendable to printing svBRDF on arbitrary shapes or 3D objects.

This invention generally relates to transparent compositions containing a blend of poly(phenylene ether) and styrenic polymer, methods for their manufacture, and food packaging films and containers derived therefrom.
