Abstract: A photopolymerizing composition and a photopolymerizing recording medium manufactured using the composition, wherein the photopolymerizing composition contains: 1.0 -99.0% by weight of at least one kind of polymerizable compound; 0.05-0.5% by weight of at least one kind of photosensitizer selected from among photochromic compounds that change color by incoherent UV light irradiation; 0.2-6.0% by weight of a coinitiator that is activated by visible light in the presence of a photoinduced form of the photochromic compound transformed by incoherent UV light to photopolymerize the polymerizable compound; 0-97.5% by weight of a polymer binding agent; 0-6.0% by weight of a plasticizer; and 0-3.0% by weight of a non-polymerizing solvent. The photopolymerizing recording medium has a high angular diffraction selectivity and thus can be effectively used to manufacture a 3D holographic optical memory with ultra high information storage capacity.

Abstract: The invention relates to photochromic monomers based on benzothiophenes and a method for preparing them, and to photochromic polymers-polyazomethines that are reversibly photocontrollable due to the introduction of photochromic fragments from the class of dihetarylethenes into their structure. The invention provides photochromic photocontrollable polymers for the creation of new information technologies.
