PURPOSE:To provide a transparent recording material wherein a precise fine image can be recorded directly with semiconductor laser beams, a stock space is small, and a miniaturized fine image can be simply confirmed by amplifying projection. CONSTITUTION:A solution wherein a developer in which a hydroxide group having a developing function is blocked with-(C=0) NH-R1 group, or-(C=0) O-R2 group (herein, R1, R2 represent a substituted or non-substituted alkyl group, a cycloalkyl group, an aryl group, an allyl group, a vinyl group, a benzyl group, a naphthyl group, etc.), an iron salt of an organic acid or a leuco dye, a near infrared beam absorbent, and a binder are dissolved uniformly in an organic solvent of MEK or the like is prepared as a spreading solution. The coating solution is spread to be dried on a base material of transparent plastics or the like so that a transparent recording layer of a 3-8mum thickness is obtained, which is enabled to record a precise fine visible image directly with semiconductor laser beams. |
