The present disclosure is directed to retroreflective articles to increase visibility of a vehicle, wherein the retroreflective article comprises one or more retroreflective markings arranged in a given pattern and at least a portion of the article has a curvature.

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.

A portable detection system comprises an energy source configured to transmit energy, a retroreflective article, a detector configured to sense retroreflective energy produced by interaction of the energy transmitted from the source and the retroreflective article, and an indicator that indicates the detection of the retroreflective energy, wherein at least one of the energy source and the detector are configured to be worn by a user.

The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.

The disclosed retroreflective element includes a highly durable core with an ionic copolymer and a plurality of beads. These disclosed retroreflective properties remain intact even after continued application of external forces and stresses. Further, the ionic copolymer allows for beads to be loaded into the ionic copolymer of the core, securely disposed around the perimeter of the core, or both.

A stereoscopic emblem includes: a retroreflective sheeting in which a surface on one side where light is incident and emitted protrudes and a recess is formed on a surface on the other side facing the protruding surface on the one side; a cured resin provided in the recess; and an adhesive layer provided on a side opposite to the retroreflective sheeting side with respect to the cured resin.
