Abstract:
A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.
Abstract:
A retroreflective article including a reflective-particle-containing binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a primary reflective layer that covers a portion of the embedded surface area of the transparent microsphere, and a secondary reflective layer provided by portions of the reflective-particle-containing binder layer that are adjacent to portions of the embedded surface area of the transparent microsphere that are not covered by the primary reflective layer.

Abstract:
The present disclosure includes in one instance an optical article comprising a data rich plurality of retroreflective meats that are configured in a spatially defined arrangement, where the plurality of retroreflective elements comprise retroreflective elements having at least two different retroreflective properties, and where data rich means information that is readily machine interpretable. The present disclosure also includes a system comprising the previously mentioned optical article, an optical system, and an inference engine for interpreting and classifying the plurality of retroreflective elements wherein the optical system feeds data to the inference engine.
Abstract:
Provided herein are retroreflective colored article having a predetermined pattern of beaded and unbeaded regions and at least one polymeric color layer (130) covering at least a portion of the beaded and unbeaded regions, a reflector layer (140) covering the colour layer, and a carrier (150). Also disclosed are methods for making the articles.
Abstract:
Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other.
Abstract:
Coatings for a surface, coating compositions, articles coated with a coating, and methods of coating are disclosed in which the coating comprises a polymer blend of polyurethane as a major component and at least one other polymer P2 having in comparison to polyurethane a higher peel strength to the surface to be coated, a higher percent elongation at break when cured, and a lower glass transition temperature, the polymer blend having been cured to form a peelable and flexible layer having a textured surface.

Abstract:
An article may include a biodata page defining a perimeter including an edge and a hinge layer attached to at least a portion of the biodata page. The hinge layer comprises a cross-linked polyurethane. In some examples, the hinge layer may include a cross-linked thermoset polyurethane.
Abstract:
Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.
