Abstract
A high speed process for forming a multi layered thin film structure in a vacuum wherein each film is less than about four microns thick and the total layers can reach upwards to 4,000 or more. The polymeric layers are formed of a cross linked component selected from the group consisting of polyfunctional acrylates and mixtures of polyfunctional acrylates and monocrylates with the component having a preferable molecular weight of between 200 and 300 and a vapor pressure preferably in excess of 1.times.10.sup.-2 Torr. The polymeric layers may be interleaved with metal layers.
