PURPOSE:To obtain an optical recording element capable of performing highly reliable high density recording, by constituting a B-layer comprising an auxochromous compound 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 B-layer 4 and the A-layer 2. The B-layer 4 comprises a monomolecular film or the built-up film thereof and each of the A-layer 2 and the light absorbing layer 3 is a laminate comprising a built-up layer,. The B- layer 4 is at first supported by a substrate and the other layers 2, 3 are laminated in predetermined order to form a laminated structure of substrate/B-layer/ light absorbing layer/A-layer. Because this 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 and color forming reaction advances through the reaction 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.

[Prior Art] Recently, optical disks have been attracting attention as a central recording device for office automation (OA). The reason for this is that a single optical disc can record (or memorize) a large amount of documents such as Bungetsu 2 Correspondence. Therefore, introducing an information storage device using this optical disc will greatly improve the organization and management of documents and literature in offices. It is expected that it will bring about change. In addition, organic materials, which have characteristics such as low cost, ease of manufacture, and high-density recording properties, are attracting attention as recording materials for optical discs.

[Problems to be Solved by the Invention] In the above-mentioned optical recording element, in order to achieve high recording density, it is desirable that the light absorption layer 6 be as thin as possible, flat, and without unevenness in film thickness. However, in conventional optical recording elements, the light absorption layer is coated on the substrate by, for example, a vacuum evaporation method or a spin coating method, so the thickness is reduced to 20%.
If an attempt is made to print thinly to a thickness of 0 to 500 Å or less, pinholes are likely to occur frequently, and the two components, the coloring agent and the sterilizing agent, come into contact at these pinholes and develop color, resulting in a drawback of lack of reliability. Furthermore, since the molecular distribution orientation within the nI2 of each layer formed by the conventional coating method described above is random, light scattering occurs within the film upon irradiation with light, resulting in small N, target density, and The degree of chemical reaction that occurs differs each time the light is irradiated. Furthermore, the above-mentioned coating method has drawbacks such as unevenness in film thickness and uneven recording quality when the substrate of an optical disk has a large area.

Next, to prevent this precipitate (organic molecules) from freely diffusing and spreading on the aqueous phase 11, a partition plate (or float) 14 is provided to limit the area of development and to control the aggregation state of the membrane substance. The surface pressure II is proportional to the aggregate state. By moving the partition plate 14, the developed area can be reduced to control the aggregation state of the film material, and the surface pressure can be gradually increased to bring down the surface pressure suitable for producing a cumulative film. The monomolecular film 16 is transferred onto the substrate by gently rolling the clean substrate 14 vertically while maintaining this surface pressure.

For example, when the substrate 15 whose surface is lignophilic is pulled out of water in a direction across the water surface, a middle molecular layer 1B with the hydrophilic edges of the organic molecules facing the substrate 15 is formed on the substrate 15J2. . When the substrate 15 is moved up and down as described above, - one monolayer is formed at each step! 6 is piled up, and the direction of the film-forming molecules is reversed in the pulling process and dipping process, so according to this method, between each layer, the parent wood group of the organic molecule and the parent wood group, and the hydrophobic group of the organic molecule and the hydrophobic group are separated. So-called Y-shaped films facing each other are formed (FIG. 4(a)).
