ABSTRACT OF THE DISCLOSURE A colored reflective plate having excellent recurrent reflectivity, durability and fabricability is produced economic- ally with high productivity by subjecting a base plate such as a steel plate, an aluminum plate and a plywood successively to the following treatments: coating and drying a colored paint on the base plate to form a primary colored layer, coating or print- ing a colored paint on said primary colored layer partially or totally with a thickness in the range from 30 to 80% of the mean radius of glass beads to be coated subsequently thereon to form an intermediate colored layer, scattering glass beads having a refractive index in the range from 1.9 to 2.1 on the surface of said intermediate layer, removing the excess of glass beads un- adhered on said layer, thrusting the remaining glass beads in the intermediate colored layer until the beads contact with the above mentioned primary colored layer, drying said intermediate layer, further coating a clear paint in the cavities among the glass beads so as to bury the beads in said intermediate and clear paint layers up to a depth from 40 to 80% of the mean diameter of the beads in total after drying, and finally drying and curing the clear paint.
