NONREFLECTIVE ARTICLES

摘要

An article for presenting dye/pigment images therein comprising a substantially transparent viewing region (20); photodeveloped, printed, deposited or diffused dyes and/or pigments (21) in the viewing region; and a substrate region (22) adjacent to the viewing region. The outer surface (23) of the viewing region is configured in a relief pattern comprising microscopic, smooth, sharp pyramids (31), cones (48), or ridges (29), to provide a series of at least 3 surface reflections of any light impinging thereon, before the light travels toward the viewer's eyes. The reflectivity at any one surface reflection is less than about 5 % of normal incident light, so less than about 0.05 % (and preferably not more than 0.02 %) of such incident light is returned toward the viewer after 3 reflections, and less after (4). A viewer thus can see the dye/pigment images clearly from any direction and free from noticeable reflected light from the outer surface, and without loss of detail or contrast in dark areas.
