Description of the invention H) TECHNICAL FIELD The present invention relates to a recording layer provided only on a disc-shaped substrate, and the light emitted from the recording layer is borrowed through the substrate. Optical, at least optical information recording media can be played. In the prior art, an optical information recording medium that mainly records or plays information using optical discs is used. The optical discs so far include CDs, CD-ROMs, CD-Rs, magneto-optical discs, or changeable discs. These are arranged on the emitted and formed colorless transparent substrate in at least a sequence such as a recording layer and a reflective layer, and the laser light is irradiated onto the recording layer through the colorless transparent substrate to constitute information recording or playback. Even in the optical disc, a dielectric layer is provided between the recording layer and the reflective layer, or between the recording layer and the substrate in accordance with the required performance. For example, the magneto-optical disc is composed of a first protective layer / substrate / first dielectric layer / recording layer / second dielectric layer / reflective layer / second protective layer. In this structure, the laser light is transmitted from the side of the first protective layer through the substrate to the recording layer, and information can be recorded on the recording layer ', and information from the recording layer is played. In addition, when recording information on a recording layer, the magneto-optical disc can also use the force of a magnetic field. In addition, most of the magneto-optical discs are in a state in which the disc is rotatable and are stored in the inside of the cartridge when used. _ The substrate of such a disc is formed by a mold injection molding method called a disc master. This injection molding-the substrate material formed, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (read the precautions on the back and then fill out this page) Order 0: -4 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention () Clearness and formability, etc. I have learned that acrylic resins, polycarbonate resins, and polyolefin resins are suitable; especially polycarbonate resins Better to use. Further, a protective layer provided on the outermost layer of the recording layer on the substrate may be used, and an ultraviolet curing resin may be used. In terms of necessary characteristics, such a disc substrate is as colorless and transparent as possible, and is required not to hinder the irradiation of laser light for information broadcasting and the like. Therefore, it is not easy to use it on the surface of the substrate (the side without the recording layer) for viewing the information displayed on the disc. In addition, on the side of the substrate on which the recording layer is provided, the composition of the film is not significantly different from the manufacturer. In other words, even if the recording capacity is between non-R media, the film composition is similar. Especially when the reflective layer is made of Al, Ag, Au, etc., and the manufacturer is different, the recording capacity is different, it is not easy to distinguish from the appearance of the optical disc. The object of the present invention is to solve the related problems to obtain The purpose is to improve the visibility of the optical information recording medium. Detailed description of the invention The bright light information recording medium of the present invention only has a recording layer and a reflective layer on at least one side of a disc-shaped substrate, and transmits light through the substrate through the substrate. Among the optical information recording media that is formed by at least the information played by the optical disc, a characteristic is that a colored layer is provided on the outer layer of the reflective layer on the substrate. In other words, because the coloring layer is provided, it is easy to see the medium from the appearance with only the eyes. In terms of coloring and coloring, if you choose to apply the Chinese National Standard (CNS) Α4 specification (2 丨 0 × 297 male t>) (please read the precautions on the back before filling this page)- Printed S8i2i > i a7 B7 of the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention ') Considering its distinguishability with others. However, for a medium without a colored layer, when the disc is seen from the side of the provided recording layer, the majority of the color of the reflective film is presented. Therefore, in terms of the layer, in order to easily distinguish the medium without the colored layer, It is better to choose a color different from the reflective film. It is also preferable that the coloring layer is a transparent coloring layer. The reason is that the colored layer is made into a transparent colored layer so that the change state of the reflective layer of the disc can be confirmed visually. However, the term "transparent" means that when light is radiated from the recording layer of the optical disc, it passes through the colored layer to reflect on the reflective layer of the optical disc, and once again passes through the colored layer and reflects back the transmittance of the colored layer. In the optical disc, a protective layer should be provided on the outer side than the reflective layer in order to improve its durability. It is necessary for the colored layer of the present invention to be provided on the outer layer of the protective layer as such, and if the protective layer is transparent, it is more preferable to provide the inner layer than the protective layer. It is also possible to use the protective layer itself as the coloring layer or its suitable material. Next, in the colored layer of the present invention, the use of the portion containing the organic pigment in the ultraviolet-curable resin promotes productivity, and is particularly favorable in terms of material cost. As for the organic pigments that are easy to use, there are known anthraquinone-based pigments: naphthoquinone series pigments, azo-based series pigments, phthalocyanine series pigments, nitrogen naphthalene series pigments, polyene series pigments, single type or mixed体 用。 Body use. Next, coating was performed by a spin coating method, and the effect was obtained by irradiation with ultraviolet rays. Alternatively, the pigment can be mixed with a volatile solution and resin, spray-coated, and then dried to form a film. There is also a coloring layer formed from a mixture of pigments and other materials' must consider the mixing and affinity of the materials. Therefore, there are materials to choose. The paper size is suitable for the country's materials (CNS> A4 specification (21〇 χ297 Gongchu) --- -6- (Read the notes on the back and then fill out this page) Order the printed textiles by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs: 5. Description of the invention. / Or in the colored layer of the present invention, the dielectric provided on the outer layer of the reflective layer is determined by the thickness and refractive index of the colored layer. The interference effect is from this side of the recording layer. The part of the disc that the eye sees when it is colored and can be seen is quite promising in terms of productivity, especially from the viewpoint of simplifying the manufacturing process. That is to say, the coloring layer composed of transparent dielectrics, such as TiC, TiN, A1N, A1TiN, etc., is different from the case of containing its organic pigment on the ultraviolet curing resin. This is to make use of the film-forming equipment of phase 1 on the reflective layer or recording layer. In particular, after the reflective film is formed by the sputtering method, the same plating target is used, and a gas different from the composition in the sputtering atmosphere when forming the civilian film is used to form the colored layer by the sputtering method from the viewpoint of productivity. The method is quite promising. That is, after forming a reflective film from A 1 or A 1 T i by sputtering, the same measurement target is used to mix N into the sputtering atmosphere to form the colored layers of A 1 Ν and A 1 T i Ν. The method is appropriate. Even with the light interference effect of the transparent dielectric provided on the reflective layer, its unique hue effect can be found. Such a situation does not necessarily require coloring of the dielectric itself. In addition, the i-light information recording medium uses environmental protection light from the surroundings as the purpose of the disc itself, so it is configured with a cassette having a state in which the disc can be rotated internally. In such a case, the cassette should be transparent to at least the part opposite to the colored layer of the disc, so that its discernability is not impaired and the disc can be protected, so it is optimistic. ^ Implementation form.

The obtained disc ~, the appearance of the disc as seen from the recording layer provided, appears golden. (2) A transparent dielectric (AlSiN) layer is formed on the reflective layer in various thicknesses by a sputtering method. The optical disc thus obtained had the appearance of the disc as seen from the provided recording layer, and exhibited metallic yellow, green, red, blue, green, etc. in base colors by film thickness. (3) The outermost layer is formed by coating a colored ultraviolet curable resin with a spin coating method on a reflective layer and irradiating ultraviolet rays to harden and form a film. Used as the outermost layer of UV curable resin (acrylic resin / Dai Nihon Ink Co., Ltd., trade name: (SD318), mixed organic pigment (Butter Yellow (cream yellow)). The optical disc (the part containing the organic pigment on the outermost layer) is seen from the recording layer provided and is colored yellow (gold). _ (4) The protective layer on the reflective layer is set with transparent UV curing Resin-based optical discs (comparative examples of the following. Optical discs) are coated with the paper mixed with the standard of China National Standards (CNS) A4 (210X297 mm).
