1292150 A7 ____B7_ V. INSTRUCTIONS (1) TECHNICAL FIELD (Please read the following notes on the back side and fill out this page) The present invention relates to a solvent composition, particularly a solvent composition useful in the manufacture of an optical recording medium. Technical Background With the advent of the multimedia era, optical recording media such as CD-R (additional recording memory using CD) or DVD-R (additional recording memory using DVD) have attracted attention. The optical recording medium can be roughly classified into an organic optical recording medium in which a recording layer is formed using an inorganic substance such as cerium, selenium or tellurium, and an organic optical recording medium in which a recording layer is formed by a light absorbing agent mainly composed of an organic dye compound. The organic light recording medium is printed by the Ministry of Economic Affairs' Intellectual Property Office and the Consumers' Cooperatives. Usually, an organic pigment compound such as a polymethine dye is dissolved in 2,2,3,3-tetrafluoro-1-propanol (hereinafter, A fluorine-substituted aliphatic alcohol such as "TFP" is used. The solution is applied to a substrate of polycarbonate and dried to form a recording layer. The reflective layer of a metal such as gold, silver or copper, and an ultraviolet curable resin are used. The protective layer is formed in close contact with each other. The organic optical recording medium has a disadvantage that the recording layer is liable to change in a light environment such as artificial light or natural light, but the solution of the organic dye compound is directly applied to the substrate to constitute a record. The layer has the advantage of being able to manufacture an optical recording medium at low cost. However, it is often used in the manufacture of optical recording media. For example, a fluorine-substituted aliphatic alcohol such as TFP is highly soluble in an organic pigment compound or a light resistance improving agent constituting a recording layer, and is often used for producing a certain quality optical record. The media is a very useful organic solvent, but recently, due to its environmental impact, it has begun to consider whether to use it or not, and propose some or all of the seven techniques.

Invention description (2) Fluorine-substituted aliphatic alcohol changed to solvent composition without fluorine-substituted organic solvent For example, JP-A-200 1 - 1 22 813 discloses acetonitrile, 1,1-dichloro-1-fluoroethane, 1,1,2-trichloro-1,2,2-trifluoro Ethane, diacetone alcohol (DAA), acetone, isophorone, diethyl ether, diisopropyl ether, THF, ethylene glycol dimethyl ether, ethylene glycol diethyl ether, ethylene glycol monomethyl ether, ethylene glycol Monoethyl ether, ME K, methyl isobutyl ketone, cyclohexanone, DMF, n-hexane n-Heptane, n-octane, n-decane, n-dodecane, cyclohexane, toluene, ethyl acetate, butyl acetate, dimethyl carbonate, dioxane, dichloromethane, chloroform, carbon tetrachloride An organic solvent of 1,1,2,2-tetrachloroethane and DMSO replaces a solvent composition of a fluorine-substituted aliphatic alcohol, which is compared with a fluorine-substituted aliphatic alcohol alone. The organic dye compound or the light resistance improving agent does not substantially reduce the solubility of the solvent composition of the fluorine-substituted aliphatic alcohol in some or all of the fluorine-free substituted organic solvent. However, recently, in an optical recording medium An organic pigment compound or a light resistance improving agent is often used. Regarding an organometallic complex such as an azo metal complex compound, a formazan metal complex compound, etc., it is desirable to replace some or all of the fluorine-substituted aliphatic alcohol. Changed to a solvent composition that does not contain a fluorine-substituted organic solvent, but most of them are soluble in a fluorine-free organic solvent, or in combination with other organic pigment compounds or light resistance improvers. As a result, it is difficult to prepare a solution having a high concentration according to the type and amount of the organic dye compound, the light resistance improving agent, and the fluorine-based unsubstituted organic solvent to be used in combination, and the crystallization is caused when the coating solution is applied to the substrate. The recording layer is uneven, and it is difficult to manufacture with excellent electronic characteristics. 迮ρ 谇Jit ( ΓΝ.ς ) A4^i^- ί 2I OX 297/zS5|· ) "" ~ (Please read the back note first) Fill in this page again)

In the current state of the art, when an optical recording medium is produced using an organometallic complex, the type and amount of the organic dye compound and the light-resistant improver actually used are combined from various organic solvents, and the most suitable organic solvent is sought from the wrong way. combination. Among the organic pigment compounds for CD-R, a flower nitrile pigment is often used, and in particular, a pentamethyne-based flower cyanoside dye having excellent light absorption and decomposition properties is used. However, when a pentamethyne-based cyanoside dye and a light-resistant improving agent are dissolved in a solvent composition containing a fluorine-substituted aliphatic alcohol and a fluorine-free substituted organic solvent, the current one of the fluorine-free substituted organic solvents is added. The method has a limit on reducing the amount of fluorine-substituted aliphatic alcohol, and it is necessary to further improve the influence on the environmental surface. On the other hand, among the organic dye compounds for DVD-R, an azo metal complex compound and a pentamethine-based flower nitrile pigment are often used. With regard to these organic pigment compounds, it is also desirable to reduce the amount of fluorocarbon substituted aliphatic alcohol. However, under realistic conditions, it is impossible to reduce the amount of fluorocarbon substituted aliphatic alcohol. In addition, the coating method is an optical recording medium manufacturing method, and the recording layer contains an organic dye compound such as an azo metal complex compound, a ruthenium metal complex compound or a flower nitrile dye, and corresponds to a CD-R specification or a DVD. The -R specification can be used for the manufacture of optical recording media that can be quickly burned, and it is desired to reduce the environmental impact or manufacturing cost of the solvent composition. DISCLOSURE OF THE INVENTION In view of the circumstances, the object of the present invention is to provide a low-cost manufacturing, which can be quickly burned according to the CD-R specification or the DVD-R specification.

As can be seen from Table 1, compared with Comparative Examples 1 and 2 using only TFP as a solvent in the control group, there is no disadvantage with respect to electronic characteristics, and it is known that jitter and block errors are displayed. The number is excellent. This is because, in addition to TFP, two or more kinds of fluorine-free substituted organic solvents are added, and after the solution containing the dissolved organic dye compound is applied to the substrate, the evaporation state of the solvent composition has a good effect on the formation of the recording film. . Further, as shown in Example 2, as a result of performing 32 times of rapid burning, a good optical recording medium was obtained without causing an obstacle to electronic characteristics. In addition, the amount of TFP used in any of the examples can be reduced. For example, the optical recording medium for DVD-R is used in the solvent composition (volume ratio is TFP: acetone = 7:3 (weight ratio is TFP) : acetone = 81 : 19)) and solvent composition (volume ratio is TFP: acetone = 1: 1 (weight ratio is TFP: acetone = 65: 35)), organic pigment compound is added (weight ratio is chemical formula 18: chemical formula 6 = 10:1), the concentration was made 1% by weight, and it was heated for a short time to dissolve. According to the usual method, the solution was uniformly applied to one side of a disk-shaped substrate 1 made of polycarbonate (a diameter of 12 cm, a thickness of 0.6 mm), and dried to form an organic pigment compound having a thickness of 10 nm. The recording layer 2 is formed. After that, the substrate 1 is evaporated with silver to have a thickness of 30 to 100 nm, and is formed in close contact with the reflective layer 3 of the recording layer 2, and is commonly used (please read the back of the back sheet and fill in the page) - - Line too 皈 尺 唐 唐嫡闱 China National Umbrella (CNS) A4 size (210X297 mm) 1292150 A7 _____B7_ V.

Further, in the comparative example, an optical recording medium was produced in the same manner as described above except that TFP was used as a solvent. For the above-mentioned two kinds of optical recording media for the DVD-R optical recording medium, a commercially available optical recording media device (product name "DDU-1000", manufactured by PULSTEC Industries Co., Ltd.) is used, and the conventional method is used at 660 nm. Burning wavelength, burning power of about 9mW, burning test signal (EFM+, basic cycle number 26.16MHz) at a line speed of 3.5 m/sec. Next, using a commercially available optical recording medium evaluation system (trade name "DVD-R CATS SA3000", manufactured by AudioDevelopment Co., Ltd.), the reflectance, modulation degree, decomposition energy, and jitter of the burn test signal were measured at a wavelength of 650 nm (read Take power is 1 mW). The reflectance is calculated as the percentage when the potential of the reflective layer is 100, and the potential is 100. Even when compared with an optical recording medium using only TFP as a solvent, the display has the same or higher electronic characteristics, and there is no problem in the characteristics of the optical recording medium. According to the above results, it is known that the use of one or more fluorine-free organic solvents in the present invention is used to reduce the amount of fluorine-substituted aliphatic alcohols for optical recording media. The electronic characteristics of modulation degree and jitter are not inferior to those of optical recording media using only TFP, and even the possibility of improving industrial use is as described above, and laser light is provided on the substrate.
