PURPOSE:To obtain an optical recording element capable of performing highly reliable high density recording, by constituting an A-layer comprising a leuco dye from a layer comprising a monomolecular film or the built-up film thereof. CONSTITUTION:An optical recording element comprises a laminate wherein an A-layer 2 comprising a leuco dye and a B-layer 4 comprising a phenolic compound are laminated and a light absorbing layer 3 is further provided on the B-layer 4 and the A-layer is formed of a monomolecular film or the built-up film thereof while the light absorbing layer 3 is formed of a built-up film and supported by a substrate 1. Because the A-layer is constituted of the monomolecular film having molecularly high degree of order and orientation or the built-up film thereof, reactive parts can be mutually isolated by the non-reactive parts in the molecule and the closely adhered constitution of the A-layer and the B-layer is enabled. The light absorbing layer is heated by the irradiation of infrared rays and, by the heat conductance thereof, the leuco dye of the A-layer and the phenolic compound of the B-layer are contacted under heating to allow color forming reaction to advance and developed color dots are formed at predetermined positions to enable the recording of information. |
