"LIVE" POLYMERISED FILMS FOR HOLOGRAM CONSTRUCTION Russian patent published in 2008 - IPC G03F7/28 G03F7/33 

FIELD: physics; measurements.

SUBSTANCE: invention pertains to polymerised films for hologram construction. Description is given of a dry photo-polymerised film, obtained from a liquid polymerising composition, containing a mixture of mono- and bi-functional acrylic oligomers and a linear thermoplastic polymer. The proposed film forms an image due to change in the refraction index when exposed to activating near ultraviolet radiation with wavelength of 350-400 nm. Description is also given of a method of obtaining the indicated film. The proposed photo-polymerised films are colourless and transparent, have good mechanical and optical properties, and are used for constructing holograms using near ultraviolet radiation with wavelength of 350-400 nm.

EFFECT: making a photo-polymerised film, with good mechanical and optical properties, used for constructing holograms using near ultraviolet radiation with wavelength of 350-400 nm.
