Abstract

PURPOSE:To obtain an optical recording element capable of performing highly reliable high density recording, by constituting all of an A-layer comprising a leuco dye, a B-layer comprising a phenolic compound and a light absorbing layer from layers each comprising a monomolecular film and 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 all of layers comprise a monomolecular membrane or the built-up film thereof and the light absorbing layer 3 is supported by a substrate 1. Because the A-layer and the B-layer are constituted of a 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 molecular 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 heat conductance thereof, the leuco dye of the A-layer and the phenolic compound of the B-layer are contacted under heating and developed color dots are formed at predetermined positions to enable the recording of information.

However, in conventional optical recording elements, the light absorbing layer is coated on the substrate-F by, for example, a blank evaporation method or a spin coating method. Pinholes tend to occur frequently, and the two components, the coloring agent and the preservative, come into contact at these pinholes and develop color, resulting in a lack of reliability.Furthermore, the film is formed using the conventional coating method described above. Since the molecular distribution and orientation within the film of each layer is random, light scattering occurs within the school due to light irradiation, and when viewed microscopically,
The degree of chemical reaction that occurs with each light irradiation differs.

層ずつ移すことができる。Four plasters, 1. The Tengmuir-Prodgett method (CLB method) developed by Langmuir et al. The Tengmuir-Prodgett method shows that, for example, in a molecule with a structure that has a parent wood group and a hydrophobic group in the molecule, when the balance between the two (balance of parent and child properties) is maintained appropriately, one molecule is on the water surface.
This is a method of creating a monomolecular film or a cumulative film of monomolecular molecules by using the fact that the parent wood group faces downward to form a monomolecular layer. The monolayer at the water surface has the characteristics of a two-dimensional system. When the molecules are sparsely dispersed, the two-dimensional ideal gas equation, nA = kT, holds true between the area A and the surface pressure ■, resulting in a gas film.Here, k is Portzmann's constant, and T is the absolute temperature.If A is made sufficiently small, the intermolecular phase lI: action becomes stronger and becomes a two-dimensional solid "condensation film (or solid film)". The condensed film can be transferred layer by layer onto the surface of carriers having various materials and shapes, such as plastic substrates and glass substrates.

A layer 2 made of a leuco dye and 8 layers 4 made of a phenolic compound are laminated, and a light absorption layer 3 is provided roughly on the B layer 4, and all of these layers are monomolecular. It is a laminate consisting of a film or a cumulative film thereof, in which a light absorption layer 3 is supported on a substrate l and laminated in the order of substrate/light absorption layer/B layer/A layer.

であった。The optical recording element according to the present invention is made of a leuco dye A.
It is composed of a layer B made of a phenolic compound and a layer B made of a phenolic compound, but conventionally, when the A layer and the +A B layer come into contact, a coloring reaction occurs, so the A layer and the B layer are brought into contact from the beginning. It was impossible to realize an optical recorder #i device with such a configuration.

ある。However, in the optical recording element according to the present invention,
Since the A and B layers are composed of a monomolecular film with a high degree of molecular order and orientation and a cumulative film thereof, it is possible to separate reactive sites from each other via non-reactive sites within the molecules. This made it possible to adopt the above configuration.

If there is a monomolecular film or a cumulative film thereof, regardless of whether it is a leuco dye molecule, for example, the aqueous moiety (alkyl chain) is the contact surface. .

きる。Furthermore, since the optical recording element according to the present invention is constructed by laminating layers A and B in close contact with each other and further providing a light absorption layer on the outside, the light absorption layer is heated by infrared irradiation.
Due to the heat conduction, the leuco substance of dyeing agent 1 in the A layer and the phenolic compound in the B layer come into contact with each other under heat, and a coloring reaction progresses, forming a coloring point at a predetermined position so that information can be recorded.
