Abstract (en)
[origin: WO2005074358A2] The invention concerns a method for the replication by hot-embossing, hot-stamping or plastic injection moulding of an optically variable transitory image relief pattern characterized by the use of a Silicon origination shim fabricated through a micromachining process. The invention also comprises objects and structures obtained according to said method.
