ABSTRACT:
Polymeric material suitable for the preparation of optical recording media for volume data storage is disclosed. The molecular structure of the material contains a main chain derived from any of poly(meth)acrylate, poly(meth)acrylamide, polysiloxane, polyurea, polyurethane, polyester, polystyrene and cellulose, and the side chains contain a) azobenzene dye, b) form anisotropic grouping, and c) at least one monomer selected from the group consisting ofwhere R=H or methyl,R′ and R″ independently denote CnH2n+1 or CnH2n-OH and R′″ denotes —CnH2N—OH.
