Abstract: A hermetically sealed retroreflective sheeting having improved resistance to delamination and improved brightness comprising a monolayer of microspheres supported in a layer of binder material, a layer of reflective material disposed behind said microspheres, and a cover film disposed in spaced relation in front of the microspheres. The cover film is in, at most, tangential contact with the microspheres. The binder material forms a network of walls surrounding individual microspheres and is in adherent contact with the cover film. Each microsphere is "exposed", i.e., air-incident.

Abstract: Reflective sheeting useful for application to a pesticide-impregnated animal collar, and animal collars made from the sheeting. The sheeting generally comprises a monolayer of transparent microspheres; specularly reflective material underlying the microspheres; a binder layer of polymeric binder material in which the microspheres are partially embedded; a carrier sheet stretchable about 10 percent or more before rupture, in which the portions of the microspheres protruding from the binder layer are embedded; a barrier layer underlying the binder layer, which sorbs plasticizers more slowly than the binder layer sorbs the plasticizers; and a layer of adhesive underlying the barrier layer.
