Cube-corner retroreflective article |
摘要 |
A cube-corner retroreflective article is provided with a number of cube-corner retroreflective element pairs each formed by a pair of cube-corner retroreflective elements sharing one side. Each of the cube-corner retroreflective elements has reflective lateral surfaces including two trapezoidal reflective lateral surfaces and one pentagonal or isosceles-triangular reflective lateral surface, and a projection shape of a quadrangle when projected onto a common plane, wherein ratios (rHA/rHC and rHB/rHC) between a length (rHC) of a ridge (HC) shared by the trapezoidal reflective lateral surfaces (HAFC and HBGC) and lengths (rHA and rHB) of other ridges (HA and HB) are in a range of 0.5 to 1.5. |
