PURPOSE:To obtain an optical recording element capable of performing highly reliable high density recording, by constituting each of a B-layer comprising an auxochromous compound and a light absorbing layer from a monomolecular film or the built-up film thereof. CONSTITUTION:An optical recording element consists of an A-layer 2 comprising a color forming compound, a B-layer 4 comprising an auxochromous compound and a light absorbing layer 3 comprising a light absorbable substance and interposed between the A-layer and the B-layer. Each of the B-layer 4 and the light absorbing layer 3 comprises a monomolecular film or the built-up film thereof and the A-layer is a laminate comprising a built-up layer. The B-layer 4 is at first supported by a substrate 1 and the other layer 2, 3 are laminated in the order of light absorbing layer/A-layer to form a laminated structure comprising substrate/B-layer/light absorbing layer/A-layer. Because the optical recording element is constituted so as to isolate the A-layer and the B-layer by the light absorbing layer, the light absorbing layer is melted or sublimed by the irradiation of infrared rays to form holes at desired positions to advance color forming reaction through the contact of the color forming compound of the A-layer and the auxochromous compound of the B-layer and developed color dots are formed at predetermined positions to enable the recording of information. |
