Document Type and Number:
Japanese Patent JPH07504045
Kind Code:
A
Abstract:
Retroreflective assembly comprising: a) a transparent globule having a first, uncoated part-spherical surface portion for reception of incident light; a second, substantially flat surface portion opposite the first surface portion; and a third, toroidal surface portion intermediate the first and second surface portions, the toroidal surface having a radius of curvature smaller than the radius of curvature of the first part-spherical surface portion; b) a monolayer of externally reflecting transparent microspheres for focusing and retroreflecting light beams incident upon the first surface portion and which have passed through, the globule, the monolayer being applied to the second surface portion and to at least a part of the toroidal surface portion; and c) a layer of diffuse reflecting pigment disposed behind the monolayer of microspheres. Optionally, a space coat is interposed between the monolayer and the diffuse reflecting pigment. In some embodiments, fluorescent pigment is used.
