PURPOSE:To obtain an optical recording element capable of performing high density recording with high reliability, by providing an A-layer comprising a leuco dye, a B-layer comprising a phonolic compound forming a color upon the contact with the leuco dye and a light absorbing layer interposed between the layers A, B and forming the A-layer from a monomolecular or built-up film layer. CONSTITUTION:An A-layer 2 comprising a leuco dye, a B-layer 4 comprising a phenolic compound the light absorbing layer 3 comprising a light absorbable substrance interposed between both layer A, B are provided to form a laminate wherein the A-layer 2 comprises a monomolecular or built-up film and each of the B-layer 4 and the light absorbing layer 3 comprises an accumulation film and the B-layer 4 is supported by a substrate 1 while substrate/B-layer/ light absorbing layer/A-layer are laminated in this order. By this optical recording element, higher density recording is enabled as compared with a conventional optical recording element. A signal/noise ratio is high and the reliability of recording can be enhanced. |
