Method for manufacturing a decorative member, particularly intended to be used as an emblem on a motor vehicle

A method for manufacturing of a decorative element, particularly intended to be used as an emblem on a motor vehicle, comprises the steps of forming a body (12) of a transparent plastic material, having a front face (12a) and a back face (12b) which comprises a base surface (13) and at least a shaped hollow impression (14a, 14b) defining a tridimensional symbol (16a, 16b) raised with respect to the base surface (13), applying a decoration layer (18) usually coloured and/or providing an ornamental pattern, on the base surface (13), and forming a metalized layer (20) on the back face (12b) by a paint containing metallic pigments so that also the inner surface of each hollow impression (14a, 14b) is coated. The pigments of the metalized layer (20) are laminar metallic pigments, and the metalized layer (20) is made by spray applying a plurality of coats of pigmented paint according to mutually crossing directions, in which the pigments are oriented parallel to the surface of the back face (12b).
