Transparent recording medium

-

, (2008/06/13)

A transparent recording medium is disclosed which can directly record a fine, precise image. With the recording medium, a compact, fine image occupying a small storage space can be easily enlarged and confirmed by an enlarged projection. It is prepared by applying a coating liquid for recording comprising a developer in which a hydroxyl group with a developing function is blocked by an N-substituted carbamoyl group or an O-substituted oxycarbonyl group, an iron salt of an organic acid or a leuco dye, a near-infrared absorbing agent, and a binder, uniformly dissolved in an organic solvent such as MEK, to a transparent plastic substrate, and drying to obtain a transparent recording layer with a thickness of 3 μm to 8μm. A visible, precise, fine direct image can then be recorded using a semiconductor laser beam.
