LIQUID COMPOSITION OF PHOTOPOLYMERISATION-CAPABLE FILM FOR HOLOGRAM RECORDING, COMPOSITION OBTAINING METHOD Russian patent published in 2016 - IPC G03F7/28 G03F7/33 G03F7/07 

FIELD: biotechnologies.

SUBSTANCE: liquid composition of a photopolymerisation-capable film for recording of holograms with gold nanoparticles preserving properties of localised gold plasmons which forms an image due to the modulation of an index of refraction at exposition by activating radiation with the wavelength of 325 nanometres, it comprises a liquid acrylic monomer with one acrylic group, bifunctional acrylate with two methacrylic groups, polymerisation photoinitiator with the activating radiation of the light with the wavelength of 325 nanometres, it differs in that the composition comprises the acrylic monomer with one acrylic group containing a limit hydrocarbonic chain in the side chain - isodecyl acrylate amounting 62.64 by wt %, bifunctional acrylate with two methacrylic groups containing urethane groups amounting - 2690 wt %, SiO₂ nanoparticles with the sizes of 7 nanometres amounting 986 wt %, dodecyl mercaptan functionalised gold nanoparticles with the size of 5 nanometres - 015 wt %, and also 045 wt % of the photopolymerisation initiator which is 2,2-dimethoxy-2-phenyl acetophenone.

EFFECT: group of inventions solves the problem of the increase of a value of modulation of a refraction index that allows using the material in the form of a thin film, also an increase of diffraction efficiency for transmission holograms has place.
