Abstract
A method of preparing a glazing, comprising: stacking a first glass sheet, a first interlayer, a photopolymer film, a second interlayer, and a second glass sheet to provide a lamination stack; deairing the lamination stack; autoclaving the lamination stack to provide a laminated glazing; applying a reactive light to the photopolymer film in the laminated glazing, wherein reactive light is applied to the laminated glazing through a master holographic film; and bleaching the laminated glazing such that the photopolymer film is no longer reactive to light exposure.
