    Abstract: A unitary lightguide including a first lightguide section extending along a first direction and a second lightguide section extending along a second direction is described. The second lightguide section includes a plurality of light extractors for extracting light that would otherwise propagate within and along the second lightguide section. The unitary lightguide includes a boundary region disposed between and joining the first and second lightguide sections and including a plurality of spaced apart light redirecting features. Each light redirecting feature includes a first portion extending substantially parallel to the first direction, and a second portion extending from proximate the first end of the first portion toward the second lightguide section and making an angle with the first portion in a range from about 10 degrees to about 70 degrees.

    Abstract: A curable composition comprises: a curable resin; and microcapsules comprising a polymeric shell enclosing a fill material including at least one of a corrosion inhibitor and a liquid vehicle, wherein the curable composition is liquid, and wherein the curable composition is essentially free of organic solvent other than the liquid vehicle. The curable composition can be coated on a metal surface of a substrate and cured to form a corrosion-resistant protective layer.

    Abstract: Described herein is a multilayered article (10) and methods of making and using such articles. The multilayered article (10) comprises: • (a) a microsphere layer (11) comprising a plurality of microspheres disposed in a monolayer; • (b) a bead bonding layer (12) comprising a first major surface and a second opposing major surface and the plurality of microspheres is partially embedded in the first major surface of the bead bonding layer, and comprises a thermoset polyurethane having a glass transition temperature of at least 35°C; • (c) a primer layer (14) disposed on the second major surface of the bead bonding layer wherein the primer layer comprises a copolymer of polyurea and polyurethane and wherein the primer layer is covalently attached to the bead bonding layer via urea linkages; and • (d) an elastomeric layer (16) disposed on the primer layer opposite the bead bonding layer, wherein the elastomeric layer comprises a polyurethane thermoplastic elastomer.
