Functional films in optical lenses and a process for their preparation by means of a bubble-free up method

A process for producing a plastic article comprising the steps of: - providing a first Giesformseitenteils (1) and a casting ring (2) which is connected to a reservoir (11) which can absorb a polymerizable monomer resin (8) and can exert a hydrostatic pressure on the finished mold, - connecting the first Giesformseitenteils (1) and the casting ring (2) to form a trough-like open casting mold, - arranging a foil (5) with a curvature corresponding to the curvature of the inside of a second Giesformseitenteils (6) substantially on the inside of the first Giesformseitenteils (1) such that between the film (5) and the inside of the first Giesformseitenteils (1) substantially no bubbles or air pockets are present, - connecting a second Giesformseitenteils (6) and the casting ring (2) to form a finished casting mold, wherein the first Giesformseitenteil (1) and the second Giesformseitenteil (6) opposite one another, so that with the casting ring (2) reservoir connected above the highest point ...
