    Abstract: Retroreflective sheeting includes a body layer having a structured surface with recessed faces and top surfaces, the recessed faces forming cube corner cavities. The recessed faces have a high specular reflectivity, while the top surfaces have a low specular reflectivity. In some embodiments a substantially continuous film of reflective material covers the structured surface, and a masking substance is provided over the reflective material at the top surfaces. Alternatively, the top surfaces are given a non-smooth surface finish so that the film of reflective material on those portions has a diffuse reflectivity. In other embodiments the film of reflective material is discontinuous, disposed selectively on the recessed faces and not on the top surfaces. A cover layer is also provided, and can bond at least to the top surfaces. Keeping the top surfaces substantially free of reflective material inhibits corrosion and can enhance the bond integrity. The top surfaces are preferably flat, and diffusely reflective to enhance the daytime whiteness of the sheeting.

    Abstract: A retroreflective article (30, 50) has opaque pigment particles (38, 58) dispersed in a retroreflective region (33, 53) of a front portion (35, 55) of a sheeting (32, 52) that includes a body portion (34, 54) and a multitude of cube-corner elements (36, 56). The opaque pigment particles (38, 58) scatter white, yellow, or light brown light to allow the retroreflective article to demonstrate improved lightness and, if colored fluorescent, improved fluorescence. The improvement in lightness and fluorescence makes the retroreflective articles more conspicuous to persons during the daytime.

    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.
