ãããŠããã The method of scanning a laser beam over a disk and reading recorded information based on the presence or absence of minute pits can significantly increase the recording density, and also makes it easy to manufacture a large number of duplicate plates from a single stamper. Because it can be used for many different purposes, it is expected to be used for things such as image and sound reproduction.

ãã The duplicate disk used in this recording/reproduction method is made of thermoplastic resin such as methacrylic resin or vinyl chloride resin, and the pits of the stamper are transferred to the thermoplastic resin by injection molding or press molding at a high temperature of 150°C or higher. This has been attempted in the past. However, the pits used for recording are usually microscopic, with a length and diameter of less than 2ÎŒ and a depth of less than 0.5ÎŒ, making it difficult to reproduce pits with high precision and resulting in a high defect rate in the production process. It has the disadvantage of being expensive.

The method for forming the photocurable coating layer is to apply the material forming the photocurable coating layer onto a plastic or glass plate, and usually the material forming the photocurable coating layer is coated with an organic solvent. Alternatively, it can be formed by diluting it with water to a viscosity that is easy to apply, and then evaporating and removing the organic solvent or water in a dryer. Alternatively, a film for a photocurable coating layer may be formed as described above on a separate support such as release paper, and the film may be laminated onto the above plastic or glass plate to form a photocurable coating layer. . The thickness of the photocurable coating layer should be 2ÎŒ or more, but
The thickness is preferably about 5 to 20Ό.

Essentially any material can be used as long as it has plasticity at temperatures below 100°C, is photocured by irradiation with ultraviolet rays, and transmits light after photocuring.In general, resin components and photocurable materials can be used. It consists of a photosensitive resin-forming component and a photosensitizer. Examples of the above resin components include acrylic resin, polyester resin, epoxy resin, polyurethane resin, polyamide resin, vinyl chloride resin, polyvinyl petral resin, cellulose derivative resin, etc., and these resin components have photocurability. It doesn't matter if you have it or not. In order for these resin components to participate in the photocuring reaction and be incorporated into a crosslinked structure, (1) introducing an ethylenically unsaturated double bond into the terminal or side chain of the resin;
A method of crosslinking by a radical polymerization reaction using free radicals generated by a photosensitizer, (2) introducing an alkaline double bond into the end or side chain of the resin,
A method of promoting addition reaction with thiol groups and crosslinking by co-existing a photosensitizer and a thiol-containing compound, (3)
Introducing a thiol group to the terminal or side chain of the resin,
A method in which a resin-forming component having an allylic double bond and a photosensitizer coexist to cause additional crosslinking during ultraviolet irradiation; (4) an epoxy group is introduced into the terminal or side chain of the resin, and Therefore, there is a method in which epoxy groups are cationically ring-opened and crosslinked using a sensitizer that liberates a Lewis acid.
In this case, the above photocurable resin forming components may or may not be used together. However, from the viewpoint of moldability, it is desirable that the photocurable resin component described above has a softening point of 100° C. or less, preferably room temperature or below, and a viscosity at room temperature of 2000 poise or more.
When the resin components are composed of only those without photocurability, it is essential to use the photocurable resin forming components in combination. The above-mentioned photocurable resin-forming component is a low molecular weight substance that usually has a molecular weight of 1000 or less and can cause the photocurable coating layer to lose its plasticity through a photocuring reaction, such as (i) a radical polymerizable component; A compound having an ethylenic double bond and having a boiling point of 200°C or more as a monomer or a compound having two or more ethylenic double bonds in one molecule.

ã§ããããšã奜ãŸããã Normally, the above-mentioned photocurable resin forming components are not suitable when used alone in the method of the present invention because they have low viscosity and high stickiness, making them difficult to handle and causing a large amount of protrusion during pressure molding. It is preferable to use the mixture together with the viscosity of 2000 poise or more at least at room temperature.
As the photosensitizer used in combination with the above resin component and photocurable resin forming component, known photosensitizers that are activated by ultraviolet rays can be used, and they can be roughly divided into (a) Photosensitizer that generates radicals
(b) There are photosensitizers that generate Lewis acids when irradiated with ultraviolet rays.

A replica disk was manufactured. The photocurable coating layer is made of 70 parts by weight of a polyester resin having a thiol group and a softening point of 70°C obtained by an esterification reaction between a hydroxyl group-terminated polyester resin and thioglycolic acid, and 15 parts by weight of diarylidene pentaerythritol. , 15 parts by weight of triallyl isocyanurate and 2 parts by weight of diethoxyacetophenone were dissolved in 100 parts by weight of ethylene glycol monoethyl ether, and the solution was coated on the above polycarbonate resin plate in the same manner as in Example 1, and dried. This photocurable coating layer had a viscosity of 2300 poise at room temperature and exhibited some stickiness and plasticity at room temperature. Thereafter, a replica disk for information recording was manufactured in exactly the same manner as in Example 1. The information recording reproduction disc manufactured in this manner had good transfer of the unevenness of the master disc, formed sharp pits, and provided a good image as a video disc.

Form a photocurable coating layer on a plastic or glass plate with a viscosity of 2000 poise or more at room temperature and plasticity at room temperature or below 100°C, and apply the photocurable coating layer to a stamper with fine irregularities. 1. A method for manufacturing a reproduction disc for information recording, which comprises: superimposing the coating layer on the plastic or glass plate, curing the coating layer by irradiating ultraviolet rays from the surface of the plastic or glass plate, and then removing the stamper from the mold.
