Triangular-pyramidal cube-corner retro-reflective sheeting

摘要: A triangular pyramidal cube corner type retroreflective sheet formed of elements useful for signs, such as a road sign and construction work sign, license plates vehicles, an automobile motorcycle, clothes, safety materials, life-saving appliance, signboards, reflective boards visible light, laser beam or infrared ray sensors. This is characterized in that inclined surface ( c surface) using one side thereof base x element sharing on bottom X-X' arranged the opposed maximally dense state has pentagonal shape; other two surfaces b surface), which share ridge extending from apex H element, having quadrangular height h to being substantially larger than h' horizontal plane (imaginary Z-Z') including bases z , w elements.
