An electron beam recording system of metallic nitrates is studied. The nitrates with PVA binder coated on conductive glasses were irradiated to the electron beam. The electron bombardment to the samples resulted a brown image formation for the silver nitrate but no visible images for the cupric and the lead nitrate. However, heating the sample at 50°C for 3 minutes after the electron bembardment gives visible images for the cupric and lead nitrates. It is found that the thermal development is effective for this system. Gelatin films containing cupric and lead nitrates did not give any visible image even if heating after the electron bombardment. However, adding hydroquinone to the gelatin films of lead and cupric nitrates, visible images were formed by heating after the bombardment. It is concluded that the image formation is caused by the reducing reaction of metallic nitrates.
