<p>A reflective plate having recurrent reflexibility in which beads are arranged in a single layer is obtained by subjecting a base plate such as a steel plate, an aluminum plate and a plywood successively to the following treatments: coating the base plate with a colored paint, printing with a colored adhesive partially on the thus obtained paint film layer by screen printing, in a thickness ranging from 30 to 100% of the mean radius of the glass beads to be applied, scattering transparent glass beads on the surface of the colored adhesive layer, removing the excess of glass beads unadhered to the adhesive, pressing the remaining glass beads into the adhesive layer until the beads contact with the colored layer above mentioned, and finally drying and hardening the adhesive.</p> |
