Abstract: A decorative plate with three-dimensional patterns is mainly made up of an upper layer and a lower layer of PPU materials wherein the upper layer is a transparent body and the lower layer has a top facet half-tone printed with patterns of special design thereon. The upper layer has a plurality of elongated and serrated solid projections disposed consecutively at the top surface thereof, each having two perspective sloping sides and one central cutting line disposed at the top thereof; whereby, patterns disposed at the lower layer are refracted to give out vivid and floating appearance when the decorative plate is turned in an angle. Moreover, the two perspective sloping sides thereof can refract one design of the patterns while the central cutting line thereof can further divide and change the patterns in different displays, effecting the variety and beauty of the decorative plate with three-dimensional patterns.
