PURPOSE:To obtain an optical recording element capable of performing highly reliable high density recording, by constituting an A-layer comprising a color forming compound 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 color forming compound and a B-layer 4 comprising an auxochromous compound are laminated and a light absorbing layer 3 is provided on the B-layer 4 and then A-layer 2 comprises a monomolecular membrane while each of the B-layer 4 and the light absorbing layer comprises a built-up film and the light absorbing layer 3 is supported by a substrate 1. Because the A-layer is formed of the monomolecular film having high degree of order and orientation or the built-up film thereof, reactive parts can be mutually isolated through 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 color forming compound of the A-layer and the auxochromous compound of the B-layer are contacted under heating to advance color forming reaction and developed color dots are formed at predetermined positions to enable the recording of information. |
