Abstract
The inventive method consists in transferring a pattern (P) onto the optical article (1) in the form of one or several portions of transferable material (3) retained by a pressure-sensitive adhesive material layer (2) and in applying transferable material portions with the aid of a pad by placing the adhesive material layer between the pad and a pattern receiving article. The use of the pressure-sensitive adhesive material makes it possible to use the different materials in the form of a transferable material. Said method is particularly suitable for producing patterns, in particular in the form of holograms on optical lenses, in particular ophthalmic lenses.
