摘要： The present invention is related to an optical recording medium comprising a substrate, a light-absorbing layer containing a near infrared absorbent and a heat-sensitive color-developing layer, these layers being superposed upon the substrate. The near infrared absorbent which is used in the present invention is prepared by mixing and heating a thiourea derivative and a metallic compound. This near infrared absorbent has relatively uniform and strong absorption spectra all over the near infrared region, and therefore, on the optical recording medium of the present invention, an image having a high resolution can be directly obtained by the irradiation of the near infrared rays.

摘要： A novel optical recording medium is here disclosed in which an underlayer and a heat-sensitive color-developing layer are laminated in this order onto a base material, the underlayer containing a near infrared absorbent, the heat-sensitive color-developing layer containing a basic colorless dye and an organic developer. The near infrared absorbent may be a dispersible near infrared absorbent which absorbs a wave length in a near infrared region of 0.7 to 2.5 .mu.m, and this dispersible near infrared absorbent is graphite, copper sulfide, lead sulfide, black titanium or tri-iron tetroxide. A transparent protective layer may be superimposed on the heat-sensitive color-developing layer.
