Compositions photopolymerizable, sensitive in the red, useful for the recording of holograms phase.

摘要

The invention relates to a photopolymerisable compositions, characterized in that they consist of a solution of: & br / (i) at least one substance selected from the group consisting of: & br / (a) the monomers containing at least one ethylenic double bond, & br / & (b) the oligomers of acrylic or methacrylic, and & br / & (c) the compounds of the addition of an acrylate or methacrylate, polyol and an acrylic acid, or derivatives of an oligomer i (b) and an acrylic acid. & br / & (ii) a free-radical generating system comprising br / (d) at least one reducing agent, & br / (e) at least one of the reinforcing agent quantic effect, & br / (f) at least one agent for absorbing light, the absorption spectrum of which extends between 600 nm and the near infrared. & br / application to the production of holograms.
