  • Publication number: 20130236708
    Abstract: A process for producing metallic structures includes an initiator composition comprising photocatalytic nanorods being applied to a substrate. A precursor composition is applied to the layer, and is reduced to form a metal by the photocatalytic activity of the nanorods. High-resolution metallic structures can be obtained by structured exposure.

  • Publication number: 20130236732
    Abstract: A method for producing metal structures includes an initiator composition comprising a photocatalytic substance being applied to a substrate. A precursor composition that can be reduced to a metal by the photocatalytic activity of the nanodusts is applied to the layer. A structure template is then applied, partially displacing the precursor composition, and then the substrate is illuminated. Structured metal structures are thus generated.

  • Patent number: 8497051
    Abstract: A composition for producing optical elements having a gradient structure, particularly for holographic applications, is formed by a refractive index gradient. The composition is produced from one or more polymerizable and/or polycondensable monomers and at least one biological polymer. A potential difference is generated for the directed diffusion of the monomers by inducing a local polymerization or polycondensation. The result is the formation of a refractive index gradient.

  • Publication number: 20130101796
    Abstract: A method for producing finely structured surfaces, in particular in plastics, includes a) applying at least one coating compound on at least one substrate; b) forming a fine structure by a die, which has the negative of a fine structure, c) curing the resultant finely structured coating compound, obtaining a substantially cured coating; and d) separating the finely structured coating from the die, wherein steps d) and c) can also be carried out in the reverse order.

  • Publication number: 20120266780
    Abstract: A process for producing encapsulated metal colloids useful as inorganic coloured pigments, including, reacting one or more glass-forming components according to the sol-gel process to obtain a sol dispersing a metal salt in the resulting sol in the presence of an additional reducing agent to form metal colloids, converting the resulting dispersion into xerogel-encapsulated metal colloids by spray drying, heating the resulting xerogel-encapsulated metal colloids to density them. The present invention relates, furthermore, to inorganic coloured pigments, in particular producible by the process of the invention, including metal colloids produced from metal salts and encapsulated in an encapsulation, the encapsulation being produced from glass-forming components according to the sol-gel process and being densified to a xerogel or glass, the proportion of metal colloid in the capsules being at least 80%.

  • Publication number: 20120129967
    Abstract: A method for producing thin films, particularly for coating surfaces, includes a) adding surface-active substances to flowable compositions comprising nanoscale inorganic particulate solids having polymerizable and/or polycondensable organic surface groups; b) forming one or more thin films stabilized by the accumulation of the surface-active substances at the interface(s), the forming of one or more thin films taking place through the generation of bubbles, foam, through the formation of minimal surfaces and/or through the wetting of surfaces; and c) solidifying the films by polymerization and/or polycondensation.

  • Publication number: 20110236804
    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.
