    Abstract: Retroreflective articles, for example in the form of pavement markers or retroreflective elements, exhibit both wet and dry retroreflectivity by using a plurality of Type A microspheres and a plurality of Type B microspheres partially embedded in a binder layer containing specular pigments. The Type A and Type B microspheres have different average indices of refraction.

    Abstract: A pavement marking (10) includes a base sheet (12), a barrier layer (30), a layer (32) of bonding material, a multitude of optical elements (34), and skid-resistant particles (36). The base sheet (12) contains rubber and fillers and has a number of protuberances (14) projecting from its front side (28). Valleys (16) are disposed between the protuberances (14). The barrier layer (30) is disposed on the front side (28) at least in valleys (16) and preferably over protuberances (14). The layer (32) of bonding material is disposed predominantly on protuberances (14) and in this position secures the optical elements (34) and skid-resistant particles (36) to the protuberances (14) but not to the valleys (16). The coverage of the front side (28) of base sheet (12) with barrier layer (30) and bonding material (32) prevents the fillers in the base sheet (12) from becoming present on the top surface of the pavement marking (10) and thereby preserves the intended color of the marking (10).

    Abstract: The articles of the present invention comprise optical elements (12) embedded in either a core having a binder layer (16) which is embedded in a road-binder (26) or optical elements (16) which are directly embedded into a binder layer (16). The binder layer may be part of a preformed pavement marking tape or may be applied directly to a traffic-bearing surface. The binder layer is comprised of a black pigment. The pavement marking articles of the present invention comprise one or more first region(s) (32) wherein the first region(s) has a daytime appearance of black and is retroreflective. In another embodiment of the present invention, the pavement marking articles further comprise one or more second region(s) (34) having a color which contrasts with black during the daytime and which is typically also retroreflective. The second region(s) is adjacent to the first region(s).

    Abstract: A pavement marking and a method of making a pavement marking, where retroreflectivity and skid-resistance can be independently controlled while making efficient use of the optical elements and skid-resistant particles. One illustrative embodiment includes two topcoats (30, 32) on a base sheet (12) having first (28) and second major surfaces, the first major surface having a plurality of protuberances (14) located thereon which are separated by valleys (16). A first topcoat (30) is attached to the first major surface of the base sheet and a second topcoat (32) is selectively located on the protuberances. A first mixture of optical elements and/or skid-resistant particles (36) is attached to, e.g., partially embedded in, the first topcoat and a second mixture (34) of optical elements and/or skid-resistant particles is attached to, e.g., partially embedded in, the second topcoat.
