Embodiment 1

[0220] First, a substrate having a thickness of 0.6 mm and an outer diameter of 120 mm, having a spiral groove (depth: 130 nm, width: 300 nm, track pitch: 0.74 μm), was injection-molded using polycarbonate resin as a raw material (1st substrate) is formed.

[0221]Next, 1.0 g of the following dye (1) was dissolved in 100 ml of 2,2,3,3-tetrafluoro-1-propanol to prepare a coating liquid. This coating liquid was applied on the surface of the above-obtained substrate on which the grooves were formed by a spin coating method to form a digital information recording layer having a layer thickness of 80 μm. Next, Ag was sputtered on the digital information recording layer to form a reflective layer with a thickness of 120 nm. Thereafter, an ultraviolet curable resin (SD318 manufactured by Dainippon Ink Chemical Co., Ltd.) mainly composed of acrylate monomers was further coated on the reflective layer by spin coating, and cured by irradiation with ultraviolet rays to form a layer with...

Embodiment 2～5

[0232] In Example 1, the optical recording medium of the present invention was produced in the same manner as in Example 1, except that the exemplary compound M-40 used as a dye in the preparation of the second substrate was replaced as shown in Table 1 below.

Abstract

Disclosed is an optical recording medium comprising a visible information recording layer, which contains a dye compound represented by the general formula (1) below, on a substrate. In the formula, R<a1>, R<a2>, R<a3>, R<b1>, R<b2> and R<b3> independently represent a hydrogen atom or a monovalent substituent (R<a2> and R<a3> may combine together to form a 5-7 membered heterocyclic ring); A represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; and n represents 0, 1, 2 or 3.

Description

technical field [0001] The present invention relates to an optical recording medium, a visible information recording method and a utilization method of a pigment compound. In detail, the present invention relates to an optical recording medium having a visible information recording layer capable of recording visible view information. Background technique [0002] Among optical recording media such as CD-R or DVD-R, there is known an optical recording medium in which the following label is attached on the surface of the substrate opposite to the recording surface of the recording layer for recording electronic information. The above-mentioned label is a label printed with the contents of electronic information recorded on the recording layer, such as titles of music data of music data or visual information such as titles for identifying recorded data. Such an optical recording medium is produced by pre-printing a title or the like on a circular label sheet with a printing m...
