  • Composition for producing optical elements having gradient structure
    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.
