(特開昭55―87595号)。 Among them, the method of recording on film with laser light is the so-called heat mode recording method, in which the laser light narrowed down by a lens is focused on the recording layer on the substrate, and is the so-called heat mode recording method, which is different from the conventional thermal recording method. Since recording can be performed without bringing the heating element into direct contact with the heat-sensitive recording layer, problems such as the heat capacity of the heating element and heat diffusion do not occur, and high-speed and high-density recording is possible. The heat mode recording method using a laser causes a physical or chemical change in the recording layer in the area irradiated with laser light based on the thermal effect of the laser light, thereby creating a gap between the irradiated spot and the non-irradiated area. This is a recording method that creates an optical density difference between the images. Recording films used in this recording method have conventionally been made by bonding metals such as molybdenum, indium, bismuth, tellurium, etc. in a thin film onto a substrate such as polyester using methods such as vacuum evaporation or sputtering. The metal can be irradiated with laser light to partially evaporate the metal for recording, and has been put into practical use in some cases for creating master discs for video discs. However, the metal used in this recording film has a high laser light reflectance, and therefore the laser light absorption efficiency is low, so the laser light required for recording requires a large output, which requires a large laser generator. However, it is not necessarily an economically advantageous recording film. In contrast to this recording film, a recording film that includes fine particles such as carbon black that absorbs heat and a coating material that binds an autooxidation binding substance such as nitrocellulose has been proposed (Japanese Patent Application Laid-open No. 43632/1983). This recording film enables negative and positive recording by irradiating laser light to transfer fine particles such as carbon black to other recording tapes. It is essential to transport the material by causing it to escape from the recording film using laser light. Therefore, it is difficult to obtain high-density recording due to the granularity of the fine particles, and a high output laser beam is still required to obtain a high optical density difference, which is the problem with recording films using metal thin films as mentioned above. The issue has not yet been resolved. Furthermore, as a recording film that can be recorded with a lower output laser beam, it has strong absorption characteristics in the wavelength range of the laser beam used for recording.
A recording film coated with a recording material that combines dyes such as methylene blue and brilliant green, which generate heat by absorbing light, and an organic substance that vaporizes at low temperatures, such as nitrocellulose, has been proposed (Japanese Patent Application Laid-Open No. 87595-1989). issue).

赤外域の光を用いることができない欠点がある。 This recording film is capable of recording by irradiating laser light to vaporize volatile organic substances such as nitrocellulose and at the same time decompose the dye. This method requires mass transfer by vaporizing organic substances. Therefore, not only is it difficult to say that the output of the laser beam used for recording has been sufficiently reduced, but also noise is generated when reading the recording film due to the bulge around the spot irradiated with the laser beam. Moreover, the wavelength range of the laser light used is limited to the visible light range, and there is a drawback that light in the near-infrared range cannot be used like a semiconductor laser.

明に到つた。 In view of this situation, the present inventors have developed a recording film that can obtain a high optical density difference using low-power semiconductor laser light by utilizing the mass transfer of heat-absorbing fine particles and organic substances as described above. Regarding the recording method used, we conducted research on a method that utilizes chemical changes caused by the thermal action of laser light.
As a result, some light absorbers are chemically stable against semiconductor laser light when used alone, but when they are exposed to semiconductor laser light in the presence of nitrocellulose, they become unstable due to the thermal effects of the semiconductor laser light. It has been found that there are compounds that undergo chemical decomposition extremely easily and lose their absorption ability. Then,
When we created a recording film using this and irradiated it with semiconductor laser light, we found that compared to conventional recording methods,
The present inventors have discovered that it is not only possible to obtain a high optical density difference using a low-power semiconductor laser beam, but also that it is possible to extremely minimize the swelling around the spot irradiated with the laser beam, and have thus arrived at the present invention.

アリールアミニウム塩類があげられる。 That is, the present invention provides a substrate containing a light absorbing agent that has a strong absorption ability in the wavelength range of semiconductor laser light used for recording and that decomposes and loses its absorption ability in the coexistence of nitrocellulose, and nitrocellulose. The present invention provides a semiconductor laser recording film coated with a recording medium of the type. The light absorbent used in the present invention is a substance that has strong absorption ability in the wavelength range of the semiconductor laser light used for recording, and that easily decomposes and loses its absorption ability due to thermal action in the coexistence of nitrocellulose. be. Through research conducted by the present inventors, it has been found that various metal complexes and aminium salts have this property. Although these metal complexes and aminium salts are chemically stable when heated or exposed to laser light alone, they decompose themselves when heated or exposed to semiconductor laser light in the presence of nitrocellulose. It has the property of easily causing chemical decomposition and losing its absorption ability at a much lower temperature.
Although the mechanism of chemical decomposition is not necessarily clear, it is presumed that the strong oxidation that appears when nitrocellulose is heated accelerates the chemical decomposition of metal complexes and aminium salts, causing them to lose their absorption capacity. That is, the light absorber used in the present invention absorbs semiconductor laser light, generates heat, transfers the heat to nitrocellulose near the absorber, causes oxidation of nitrocellulose, and causes chemical decomposition due to the oxidation. It has the property of causing absorption and loss of absorption capacity. There are six types of such absorbents: aromatic diamine metal complexes, aliphatic diamine metal complexes, aromatic dithiol metal complexes, aliphatic dithiol metal complexes, mercaptophenol metal complexes, and arylaminium. Salts can be given.

種以上の溶剤を用いることが可能である。 The semiconductor laser recording film of the present invention has the above-mentioned light absorption ability and a recording medium containing a light absorbing agent and nitrocellulose, such as one prepared by mixing and dissolving nitrocellulose and other media as necessary in a suitable solvent. It is obtained by coating on a transparent substrate such as glass or plastic film such as polyethylene terephthalate or polycarbonate, which transmits semiconductor laser light and has heat resistance. When reading information recorded with a laser beam, unlike the case where the amount of transmission of the reading laser beam is detected, when reading by the amount of reflected light of the reading laser beam, metal evaporation is performed on the substrate and then metal evaporation is performed. The semiconductor laser recording film of the present invention can be obtained by applying a recording medium containing the above-mentioned light absorbent and nitrocellulose onto the layer. Further, in a recording medium coated on a substrate, the addition ratio of the light absorbent to nitrocellulose is 1 to 50% by weight, but usually 3 to 30% by weight is preferable. If the addition ratio is large, the adhesion between the coating film and the substrate will deteriorate, and if the addition ratio is small, it will be difficult to obtain a sufficient optical density difference. In addition, acrylic resins such as polymethyl acrylate and polymethyl methacrylate, cellulose acetate, etc. are appropriately added to the recording medium in order to improve the adhesion between the coating film and the substrate and the economic stability of the coating film. Organic polymer compounds such as cellulose derivatives other than nitrocellulose, vinyl resins such as polyvinyl chloride and polyvinyl chloride-polyvinyl acetate copolymers may be added. In addition, solvents for dissolving the light absorber and nitrocellulose include ketone solvents such as acetone and methyl ethyl ketone, alcohol solvents such as ethanol and isopropanol, cellosolve solvents such as methyl cellosolve and ethyl cellosolve, ethylene glycol monomethyl ether, diethylene glycol monomethyl Any one of glycol ether ester solvents such as ether acetate, chlorine hydrocarbon solvents such as dichloromethane, chloroform, etc.

ある。 In order to perform laser recording by irradiating the semiconductor laser recording film of the present invention with semiconductor laser light, a laser light having a wavelength in the absorption wavelength region of the light absorbing agent contained is selected from various semiconductor lasers and used. In addition, if the semiconductor laser used is focused with a lens into a spot beam of usually 2μ or less and irradiated onto the recording film, real-time laser recording with a high optical density difference using high-density, low-energy laser light can be achieved. It becomes possible. That is, the semiconductor laser recording film of the present invention can obtain extremely high density and optically high density difference using low-power semiconductor laser light, and can also use various types of semiconductor laser light in the near-infrared region by selecting a light absorber. It is possible to directly reduce the output of the laser beam used for recording and use it as a reading beam, and it is a real-time recording that does not require post-processing such as phenomenon fixation.
Furthermore, it has the advantage of not being exposed to indoor light, so there is no need for darkroom operations. It can be widely applied to
