Abstract

A method for producing hemispherically coated reflex-reflective microspheres for slurry application to a substrate. The method comprises the steps of coating a carrier web with a first adhesive layer; removably embedding a plurality of microspheres into the first adhesive layer, so that one hemisphere of each of the microspheres is embedded therein, the remaining portion of the microspheres remaining exposed from the first adhesive layer; applying a reflective material layer to the exposed hemispherical portion of the microspheres, causing them to be reflex-reflective microspheres; removing the microspheres from the first adhesive layer; and, maintaining the microspheres in water for slurry application.
