Claim 0:
1. A method for manufacturing a part comprising at least one three-dimensional metallised pattern overlying a local enamel underlayer; the method comprising the steps of:
providing a substrate on which are formed, beforehand, in three dimensions, at least one enamel pattern;
depositing at least one metallisation layer on the at least one enamel pattern;
depositing a resin layer on the at least one metallisation layer;
selectively working the resin layer, so as to locally form resin portions corresponding to or complementary to the at least one three-dimensional pattern;
removing the resin portions complementary to the at least one three-dimensional pattern, as well as underlying portions corresponding to the at least one metallisation layer; and
removing remaining resin portions, so as to reveal the at least one corresponding three-dimensional metallised pattern, the or each pattern being made of a material of the metallisation layer deposited on the local enamel underlayer.
