摘要： A pavement marker having improved daytime visibility comprises a transparent fluorescent top portion having a top surface and a front edge. Light received by the top surface of the top portion results in light being directed internally through the top portion and emitted from the front edge, thereby providing a daytime signal to drivers of oncoming vehicles. In an alternative embodiment, the top portion can comprise a polymer having in its backbone moieties that either absorb U.V. light or that are capable of undergoing rearrangement to moieties that absorb U.V. light, to provide greater fluorescent durability. The polymer can be present either within the fluorescent top portion or as a U.V. light screening layer on top of the top portion.

摘要： Both a metallized cube corner retroreflective sheeting having a high measured daytime luminance factor and a method of manufacture thereof are provided. The sheeting is formed from a transparent planar sheet material including on one side a dense array of retroreflective cube corners having height H. The cube corners are canted edge-more-parallel by within about 1.5 degrees of 10n-9 degrees, where n is the index of refraction within the cube corners, and the cube corner faces are metallized by the application of a thin coating of reflective metal. The thickness of the sheet material between the bases of the cube corners and the opposite side of the sheeting is preferably between 1.75 H and 4.00 H. The resulting metallized, retroreflective sheet material may be mounted on a vehicle to increase its nighttime visibility through the ability of the sheet material to efficiently retroreflect a beam of light from a headlight or other source across a broad range of incident and orientation angles. Advantageously, the sheeting also reflects at least about 3.5% of normal and near normal light at angles within 5° of 45° obliquity, advantageously giving it a high measured daytime luminance factor as required by transportation regulations.

摘要： A method for tooling a pattern of retroreflective microcubes, which pattern can be subdivided into smaller increments within which there are straight line tooling paths, none of which pass through an otherwise solid part of the incremental pattern. The tooling paths within the various increments need not be parallel to a common plane. Various adaptions of the method enable the tooling of a number of specific microcube shapes and for modifying such optical properties of the microcubes as entrance angularity, incidence angularity, orientation angularity, observation angularity, percent active aperture and retroreflectance. Specific techniques govern the pre-selection of cube parameters such as cube axis cant, cube apex decentration, and cube boundary proportions, which parameters can be adjusted independently of each other. Designs tooled by the method can have 100% active aperture at near zero degrees entrance angle. The method involves providing a plurality of plates of micro thickness, each plate having at least one end comprised of a material that can be tooled with polished surfaces by means of an appropriate tool, tooling on said end of each plate an increment of the pattern, and assembling the plates together in various ways to form a master. Retroreflective articles made by means of this technique are expected to provide superior performance when used in pavement markers, highway signs and other applications.
