Abstract
Method for producing novel microparticles, such as 1&mgr; to 20&mgr; diameter glass beads, by coating them to improve their flowability and to enable them to be distributed in predetermined depths of novel plastic coatings, extrusions, molded bodies, etc. The thin microparticle coatings are repellent to each other and to the plastic binder material, to predetermined degrees, to cause the particles to distribute adjacent the surface of the plastic body, or at a predetermined depth therebelow, to produce desired color-enhanced properties.
