A robust sintered retroreflective composite comprising, a core bead, a peripheral bead, and an interphase coating. The bead can be used in typical retroreflective indicia and uses.

Retroreflective sheeting comprising cube corner microstructure and having channels substantially parallel to a longitudinal, peripheral edge of the sheeting

A display system comprises a projector combined with a retro reflective screen and a viewer distance from the projector such that the observation angle is less than approximately 2-3 degrees. The brightness of the image on the screen for the proposed display system is increased by a factor of 100-500 as compared to traditional display systems with for an equivalent power/intensity light source.

A method of manufacturing a combined photoluminescent and retroreflective sheet material is disclosed. The method comprises the coating of at least part of one side of a sheet of a substrate (3) such as a fabric substrate, with a mixture of an adhesive and a photoluminescent pigment. The mixture preferably comprises between 20% and 70% inclusive of a photoluminescent pigment having a size between 20 microns and 60 microns inclusive. The adhesive is preferably a transparent adhesive. The coated sheet of substrate (7) is then cured prior to the securement of one or more pieces of a retroreflective sheet (9) o one or more predetermined areas of said one side of the sheet of the substrate to form the sheet material such that at least 5% of visible area of said one side of the sheet material is photoluminescent.

A marker composition and a package using same. The marker composition can include retroreflective particles and a dispersion medium, the blending ratio of the retroreflective particles being from 50 to 90 mass % on the basis of the total marker composition.

Retroreflective articles include transparent microspheres (120) protruding from a bead bond layer (140), with reflective metal layers (130) coated on a portion of the transparent microspheres. Retroreflective articles with anti-staining properties have bead bond layers that contain one or more corrosion inhibiting compounds. At least a portion of the one or more corrosion inhibiting compounds migrates through the reflective metal layer to passivate the exposed metal surface of the reflective metal layer.

A multi-part medical marker (1) comprising a marker core consisting of at least two corresponding parts (2a, 2b) and comprising a detectable surface, wherein the surface is substantially formed from a detectable coating (4) which is applied to the surface (3) of the parts (2a, 2b) of the marker core (2). An apparatus for producing a medical marker comprising a marker core (2) and a detectable surface, comprises: a first feeding device (16) for providing the marker core (2); an application device (17) for applying a detectable layer to the surface (3) of the marker core (2); anda transport device (18) for transporting the marker core (2) within the apparatus
