Abstract:
Method for fabricating a transparent display dial for a portable object, wherein the method includes the steps of: creating a mold with a first relief pattern for imprinting a decoration on at least a first portion of the surface of the transparent display dial, and with a second relief pattern for imprinting an antireflective filter on a second portion of the surface of the transparent display dial; depositing on the dial a mixed layer of a monomer and a cross-linking agent sensitive to ultraviolet radiation; applying the mold on the mixed monomer and cross-linking agent layer; solidifying the mixed monomer and cross-linking agent layer by photopolymerization under ultraviolet irradiation through the mold, and after insolation, removing the mold. The invention also concerns a transparent display dial obtained according to the method of the invention.
