Image recording medium and method of producing the same
View Patent ↗An image recording medium includes a first electrode layer permeable to a recording electromagnetic wave carrying thereon image information, and a recording photoconductive layer which contains a-Se as a major component and becomes conductive upon exposure to the recording electromagnetic wave which are superposed one on another in this order with an inhibition layer for inhibiting interfacial crystallization of the recording photoconductive layer intervening between the first electrode layer and the recording photoconductive layer. The inhibition layer is formed by coating the surface of the recording photoconductive layer with organic polymer by the use of low boiling point solvent.
1. A method of producing an image recording medium comprising a first electrode layer permeable to a recording electromagnetic wave carrying thereon image information, and a recording photoconductive layer which contains a-Se as a major component and becomes conductive upon exposure to the recording electromagnetic wave which are superposed one on another in this order with an inhibition layer for inhibiting interfacial crystallization of the recording photoconductive layer intervening between the first electrode layer and the recording photoconductive layer, and recording the image information carried by the recording electromagnetic wave by storing electric charges generated by the recording photoconductive layer upon exposure to the recording electromagnetic wave, wherein the improvement comprises that the inhibition layer is formed by coating the surface of the recording photoconductive layer with an organic polymer in a low boiling point solvent and drying the coating at room temperature.
2. A method as defined in claim 1 in which the organic polymer is a small water content polymer.
3. A method as defined in claim 2 , wherein the small water content polymer is selected from the group consisting of polycarbonate, polystyrene, polymethyl methacrylate, polyvinyl acetate and polyvinyl chloride.
4. A method as defined in claim 3 , wherein the small water content polymer is polycarbonate.
5. A method as defined in claim 1 in which the low boiling point solvent is not higher than 65° C. in boiling point.
6. A method as defined in claim 5 in which the low boiling point solvent is a chlorinated hydrocarbon or a fluoride.
7. A method as defined in claim 6 , wherein the chlorinated hydrocarbon is selected from the group consisting of methylene chloride, chloroform, 1,1-dichloroethane and 1,2-dichloroethylene.
8. A method as defined in claim 6 , wherein the fluoride is selected from the group consisting of 1,1-dichloro-1-fluoroethane and 1,1,2-trichlorotrifluoroethane.
