Photopolymer Composition for the Manufacturing of Holographic Media

摘要

(Meth)-acrylate compound (I), is new. (Meth)-acrylate compound of formula (CH 2=C(R1)-C(=O)-A-N(R2)-C(=O)-X-R3) (I), is new. R1, R2 : H or organic residue; R3 : organic, optionally aromatic residue with 1-30C, which comprises up to 29 heteroatoms from O, N, S, Se, P or halo; A : optionally saturated, optionally branched and/or cyclic (C1-C6)-alkylthio, saturated, optionally saturated, optionally branched and/or cyclic (1-6C)-alkyloxy, polyethylene oxide or polypropylene oxide (preferably each with 2-6 monomer units in polymer chain (m is 2-6) is bonded via C on N); and X : O or N, which is optionally substituted with optionally branched (1-6C)-alkyl. An independent claim is also included for a photopolymer formulation comprising a matrix polymer, the writing monomer (I), and a photoinitiator.
