2. Description of the Related Art

Techniques by which a phthalocyanine is applied to an optical recording medium are described in U.S. Pat. No. 4,298,975, EP 353,394 and U.S. Pat. No. 4,769,307. However, the phthalocyanines disclosed in these patents are insufficient in points of sensitivity and refractive index as phthalocyanines for optical recording media.

Particularly, in the writable (recordable) compact discs (CD-WO), laser beams in the vicinity of 780 nm are utilized for writing and reading of records, and therefore it is important to control the absorptivity coefficient, the refractive index and the reflectance of a recording material at about 780 nm. Thus, it has been desired to develop phthalocyanines suitable for recording materials for CD-WO which have a good structure stability, a high refractive index for beams at about 780 nm, excellent resolution properties and a high sensitivity.

That is, sodium alkoxide which was obtained by reacting an alcohol with sodium hydride was reacted with the nitrophthalonitrile at 0.degree.-100.degree. C. to obtain the alkoxy-phthalonitrile.

The synthesis of a halogenated alkoxyphthalonitrile was effected by halogenating the alkoxyphthalonitrile in accordance with the method described in I. T. Harrison and S.

The halogenating agent is suitably used in a molar ratio of from 1 to 2 per mole of the alkoxyphthalonitrile.

The halogenated alkoxyphthalocyanine of the present invention is suitable for the recording layer material of an optical recording medium.

An optical recording medium which comprises the halogenated alkoxyphthalocyanine described above, has good quality. The medium can be manufactured by the following process:

The medium is substantially composed of a transparent substrate and recording layer. If desired, the medium has also an optical reflective layer and a protective layer.

The substrate can be made from an optically transparent resin. Examples of such resin include acrylic resin, polyethylene resin and polycarbonate resin. Furthermore, the substrate may be surface-treated with a thermosetting resin or an ultraviolet-setting resin.

The recording layer can be prepared by coating the above compounds on the substrate. In the coating method, a binder resin and the above compounds are dissolved in a solvent so that concentration of the binder resin and the above compounds may be 20% by weight or less, preferably 0%, i.e., absent and 0.05 to 20% by weight, preferably 0.5 to 20% by weight, respectively, and then application is carried out by using a spin coater. The thickness of the recording layer is preferably from 50 to 300 nm.

Considering solvent resistance of the substrates, such a solvent as exemplified below is preferably used in the spin coating. Examples of such preferably usable solvents include halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride, trichloroethane, dichloroethane, tetrachloroethylene and dichlorodifluoroethane; ethers such as diethyl ether, dipropyl ether, dibutyl ether and dioxane; alcohols such as methanol, ethanol, propanol and butanol; "CELLOSOLVES" brand name for ethanediol ethers and ether esters such as "METHYL CELLOSOLVE" a brand name for 2-methoxyethanol, "ETHYL CELLOSOLVE" a brand name for 2-ethoxyethanol "PROPYL CELLOSOLVE" a brand name for 2-butoxyethanol and "BUTYL CELLOSOLVE" a brand name for 2-butoxyethanol; ketones such as trifluoroacetone, hexafluoroacetone and hexafluoro-2-butanone; and hydrocarbons such as hexane, octane, cyclohexane and cyclo-octane.

The reflective layer comprises aluminum or gold. The reflective layer can be prepared by vapor depositing or sputtering. The thickness of the reflective layer is preferably 1 to 200 nm.

Preferred protective layer is transparency and can be prepared by applying an ultraviolet curing resin or thermosetting resin with a spin coater and then curing the resin. The thickness of the protective layer is preferably from 1 to 500 .mu.m.

When the optical recording media are manufactured, it is preferred from the viewpoints of cost and users' handling that the polyacrylate or polycarbonate substrates are employed and that the application is made by the spin coating technique.
