Multi layer structure and process for making same

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 polyacrylates and mixtures of polyacrylates and monocrylates with the component having a preferable molecular weight of between 200 to 300 and a vapor pressure preferably in excess of 1 X 10⁻² Torr.
