Abstract
A photorecording medium contains a polymeric matrix, typically cross-linked to provide a desired level of physical stability, and a photoimageable system containing a photoactive monomer. Unlike previous polymer media, which tend to contain a substantially homogeneous dispersion of photoimageable system and matrix polymer, the matrix and photoimageable system of the invention are phase separated, yet still exhibit low light scattering such that useful holographic properties are possible.
