Abstract: In order to provide, during final production, the raised symbols of reflectorized motor vehicle license plates permanently with paint in the hot-embossing process, and to be able to use therein a narrower and thus less expensive, heat-releasable paint layer provided on a synthetic resin carrier film, it is suggested to create the coloring of the rim already prior to cutting off the blank of the license plate and prior to embossing the plate rim.

Abstract: The reinforcing construction member of synthetic resin for motor vehicle license plates comprises a marginal bead surrounding the stamped rim of the license plate and a surface in contact with the reverse side of the license plate. It is fashioned as a frame (1) with an angular profile (5, 6) covering the stamped rim of the license plate all-around from the front and from the side. The surface of the reinforcing construction member in contact with the rear side of the license plate consists of several partial surfaces formed, on the one hand, by connecting webs (9) shaped integrally with the angular profile (5, 6) of the frame and bridging respectively two mutually parallel-extending lateral parts thereof and, on the other hand, by holding lugs (10, 11) shaped at the two other lateral parts (4) of the frame, one of these holding lugs (10) being shorter than the other.
