POLYURETHANE COMPOSITION FOR MANUFACTURING HOLOGRAPHIC MEDIA, ITS APPLICATION, METHOD OF HOLOGRAM RECORDING AND UNSATURATED URETHANES Russian patent published in 2014 - IPC C08G18/67 C08G18/76 C08G18/77 C08L75/16 G03F7/28 G11B7/245 G03H1/04 

FIELD: chemistry.

SUBSTANCE: claimed invention relates to polyurethane composition for manufacturing holographic media, which includes component of recording monomer a), which contains as recording monomers calculated per the entire composition of, at least, 10 wt % of one or several unsaturated urethanes a) from group of formula (I) and (III) compounds, as well as polymer compounds or respective matrix precursors, formed from isocyanate component b), reactionable with respect to isocyanates of component c), as well as from one or several photoinitiators d) as matrix for recording monomers, where R independently on each other in each case represents radiation-solidified group, and X independently on each other in each case represents single bond between groups R and C=O or linear, branched or cyclic, containing, if necessary, heteroatom, and/or, if necessary, functionally substituted hydrocarbon residue with from 2 to 40 carbon atoms. Also described is method of producing media for recording visual programmes, application of thus obtained media and method of hologram recording.

EFFECT: application of polyurethane composition, providing production of safe holograms for application in optics in the entire visual area.
