Abstract: PROBLEM TO BE SOLVED: To obtain the subject material by including a monomer, an expanding agent, and a specific material causing no volume contraction so as to desirably avoid contraction induced by the polymerization of the monomer and afford products useful as holography recording media or the like. SOLUTION: This material comprises (A) a polymerizable photoactive monomer, (B) an expanding agent capable of inducing cleavage when this material is exposed to radiation, and (C) a material causing no volume contraction exceeding 0.4%, pref. 0.2% of this material per molar concentration of the functional group in the monomer involved in the polymerization when this material is exposed to radiation at

Abstract: PROBLEM TO BE SOLVED: To substantially prevent the both of the mutual reaction of optically active monomers and a matrix precursor during hardening and the inhibition of the following polymn. of the monomers by making a matrix polymer and a polymer produced from the polymn. of the one kind of plural optically active monomers compatible with each other. SOLUTION: This optical product is composed of a three-dimensionally crosslinked polymer matrix and one kind of plural optically active monomers and makes at least the one kind optically active monomer contain a part which is substantially independent of the polymer matrix other than a monomer functional group. Then, the matrix polymer and a polymer produced from the polymn. of the one or plural optically active monomers are made compatible with each other. A polymn. reaction carefully considered for the formation of the matrix polymer is, e.g. cationic epoxy polymn. cationic vinyl ether polymn., cationic alkenyl ether polymn. cationic allene ether polymn. or cationic ketene acetal polymn.

Abstract: An improved recording medium is provided having a rigid porous matrix containing a photoimageable system. In contrast to previous media containing porous matrices, the invention allows readable holograms to be written in a medium without the need for solvent processing steps subsequent to irradiation. Due to the rigid nature of the matrix, polymerization and/or diffusion during formation of each individual hologram induces only a small level of Bragg detuning. Temperature fluctuations similarly induce only a small Bragg shift. Improved archival life of recorded holograms and improved fidelity of read-out, as well as improved optical elements, are thereby attained. And the avoidance of solvent processing makes the process of recording holograms far easier than in previous porous matrix-based media.
