- 2. A hologram recording device comprising
- (i) a recording layer comprising a hologram recording material according to claim 1; and
- (ii) transparent electrode layers provided on each side of said recording layer.
- 3. A method of manufacturing a hologram recording device comprising at least the steps of:
- (1) preparing a solution containing at least one polymer composition having a photoconductive component in the solid state, a second-order super-polarization component and an electron or hole capturing component;
- (2) forming a plurality of films of said polymer composition by successively coating said solution of said polymer composition and then drying said coating;
- (3) fusing together said plurality of films formed in step (2) by sandwiching said plurality of films as a stack between two transparent substrates each with a transparent electrode layer formed on one side such that said transparent electrode layer is in contact with said film stack using a heating press, and
- (4) heating said fused recording layer to a temperature of about or above the glass transition temperature of said polymer composition while applying an electric field between said transparent electrode layers, and subsequently cooling down the heated recording layer,
- wherein said polymer composition is:
- (I) a copolymer of 2-(N-carbazolyl) ethyl acrylate and 2-(4-(.beta.,.beta.-dicyanovinyl) phenoxy) ethyl methacrylate, dibutyl phthalate, and trinitrofluroenone;
- (II) a copolymer of 3-(N-ethylcarbazolylmethyl) acrylate and 2-{N-(4-(.beta.-cyano-.beta.-ethoxycarbonylvinyl))-N-methyl anilino}ethyl methacrylate, dibutyl phthalate, and trinitrofluorenone;
- (III) a copolymer of 2-(N-carbazolyl) ethyl acrylate and 2-{N-(4-(.beta.-cyano-.beta.-ethoxycarbonylvinyl))-N-methyl anilino}ethyl methacrylate, and trinitrofluorenone; or
- (IV) a copolymer of 2-(4-(.beta.,.beta.-dicyanovinyl) phenoxy) ethyl methacrylate and methyl methacrylate, polycarbonate, a vinylcarbazole oligomer, and N, N'-diphenyl-N'N'-bis (3-toluoyl)-4,4'-diaminobiphenyl.
- 4. A method of hologram recording comprising (i) irradiating a coherent beam at each side of a recording layer comprising at least one polymer composition, said polymer composition having a non-centro symmetric structure and having a photoconductive component and a second-order super-polarization component, and (ii) applying a DC voltage during said coherent beam irradiation between transparent electrode layers provided on each side of said recording layer, wherein said polymer composition is:
- (I) a copolymer of 2-(N-carbazolyl) ethyl acrylate and 2-(4-(.beta.,.beta.-dicyanovinyl) phenoxy) ethyl methacrylate, dibutyl phthalate, and trinitrofluroenone;
- (II) a copolymer of 3-(N-ethylcarbazolylmethyl) acrylate and 2-{N-(4-(.beta.-cyano-.beta.-ethoxycarbonylvinyl))-N-methyl anilino} ethyl methacrylate, dibutyl phthalate, and trinitrofluorenone;
- (III) a copolymer of 2-(N-carbazolyl) ethyl acrylate and 2-{N-(4-(.beta.-cyano-.beta.-ethoxycarbonylvinyl))-N-methyl anilino} ethyl methacrylate, and trinitrofluorenone; or
- (IV) a copolymer of 2-(4-(.beta.,.beta.-dicyanovinyl) phenoxy) ethyl methacrylate and methyl methacrylate, polycarbonate, a vinylcarbazole oligomer, and N, N'-diphenyl-N'N'-bis (3-toluoyl)-4,4'-diaminobiphenyl.
