  • Patent number: 9052588
    Abstract: A composition for producing optical elements has a gradient structure, particularly for holographic applications, wherein the gradient structure is formed by a refractivity gradient. The composition is produced from a polymer and a light- and/or temperature-sensitive metal complex and the light- and/or temperature-sensitive metal complex is decomposed upon changing the local refractivity. The result is the formation of a refractivity gradient.
    Type: Grant
    Filed: October 16, 2009
    Date of Patent: June 9, 2015
    Assignee: Leibniz-Institut fuer Neue Marterialien gemeinnuetzige GmbH
