Patent

CA 2706977

A composition for holographic recording is provided, comprising an inert polyphenyl ether binder capable of supporting radical polymerization, wherein the inert binder is substantially transparent in visible light, and is viscous at room temperature; a photopolymerizable part comprising a matrix forming component comprising at least one radically photopolymerizable multifunctional (meth)acrylic oligomer or monomer, and a radically polymerizable recording component; and a photoinitiation system capable of initiating radical polymerization.

L'invention porte sur une composition pour un enregistrement holographique, comprenant un liant à base d'éther polyphénylique inerte capable de supporter une polymérisation par voie radicalaire, le liant inerte étant sensiblement transparent dans la lumière visible et étant visqueux à température ambiante ; une partie photopolymérisable comprenant une matrice formant un composant comprenant au moins un oligomère ou monomère (méth)acrylique multifonctionnel photopolymérisable par voie radicalaire et un composant d'enregistrement polymérisable par voie radicalaire ; et un système de photoinitiation capable d'initier une polymérisation par voie radicalaire.
