Title:
RECURRENTLY REFRACTIVE PAINT
Document Type and Number:
Japanese Patent JPS5317643
Kind Code:
A
Abstract:
Novel magnetically orientable retroreflectorization particles permit application of highly oriented retroreflective coatings. The retroreflectorization particles individually comprise at least one transparent microsphere, specular reflective means in optical connection with a first portion of said microsphere so as to provide retroreflection of light incident on the opposed portion of the microsphere, and a magnetic layer underlying said specular reflective means and having a magnetic axis parallel to the optical axis on which said first and opposed portions of the microsphere are aligned. When the particles are applied to a substrate in the presence of a magnetic field having flux lines of appropriate polarity perpendicular to the substrate, the particles tend to become aligned in a common direction that retroreflects light incident on the coating.
