    Abstract: There is provided a reflector capable of reflecting light at a wide angle of incidence, for which the manufacturing time can be easily shortened even if a comparatively hard reflection sheet is used and of which the reflection sheet is effectively prevented from being cracked or peeled from the supporting body. A reflector comprising: a supporting body (1) which has a base (11) and a plurality of projections (12) having a sloping surface (120), and a reflection sheet (2) disposed on the surface of the base and sloping sections (120) of the projections (12); wherein the length of the surface (10) between the projections in the direction of width is larger than the length of the projection in the direction of width, and the surface of the base (1) has at least one peripheral surface (101b) of each projection (12) extending along the periphery of the direction of width of the projections (12) at each of the projections (12); and the reflection sheet (2) further includes a peripheral section (22b) disposed on the peripheral surface (101b) of each projection, and the sloping section (21) of the reflection sheet (2) is linked with one (20a) of the two adjacent sections (20a, 20b) between the projections (12) and separated from the other section (20b) and the peripheral section (22b) of the projection.

    Abstract: The invention concerns surfacing materials comprising a binder applied on a concrete, bitumen, textile, wooden or other substrate, in one single coat whereon are sprayed, prior to polymerisation, mass-coloured glass microbeads, in a single self-levelling layer comprising a filler of mass-coloured glass beads. When used for road marking, the sprayed self-levelling layer of mass-coloured glass beads comprises a plurality of anti-skid protrusions emerging above the water film formed on said marking in rainy weather, enabling retroreflection of light from headlights day and night on the beads integral with said protrusions. The glass beads are mass-coloured by melting, in a gas, electric or plasma burner furnace, silica contained in sand with native oxides depending on the type of matrix which encloses the grit, imparting their colour thereto.

    Abstract: This disclosure provides a concrete product having a retroreflective surface with uniform and sharp edge which is produced easily with shortened time without using a special equipment or process as well as chemicals which need special attention in handling. The disclosure also establishes a method to obtain the substrate consisting of a concrete-based material and a retroreflective element dispersed and embedded at least in a surface portion of said substrate, at least a part of which element is exposed from a surface of said substrate and the said retroreflective element being exposed from the substrate surface as a result of partially retarded hardening of the said concrete-based material and removal of the thus produced, unhardened concrete material.

    Abstract: Retroreflective articles of the invention comprise a continuous base layer (16) and a multi-color polymeric top layer. The invention also includes methods of making such retroreflective articles. The retroreflective articles of the invention provide excellent daytime contrast while maintaining nighttime retroreflectivity. Variously colored segments of polymer are directly and either sequentially or simultaneously coated onto a continuous backing to form a multi-colored top layer. Durability over existing multi-colored retroreflective articles is enhanced by use of a continuous base layer.

    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.
