Abstract
The present invention relates to a recordable optical recording medium, particularly to an optical recording medium with high density. The optical recording medium comprises a base material on which a recording layer is deposited. The recording layer comprises at least one kind of laser absorption dye represented by formula (I), wherein Q represents a benzene ring or a naphthalene ring substituted by the alkoxyls of C1 to C4, R1 and R2 respectively represents the alkyl radicals of C1 to C8, Y represents H2 or the alkoxyls of C1 to C4, and X<-> is a negative ion.
Description
Technical field
The present invention relates to optical recording media, and be particularly related to a kind of high-density optical recording media.
Background technology
Use organic material mainly can be divided into cyanine dye, the blue or green dyestuff of phthalein and azo dyes three major types at present as cd-recordable (CD-R) recording layer, the denominator of this three classes dyestuff is: its at the maximum absorption wavelength of visible-range between the 650nm to 750nm, its major function is to absorb 780nm laser and convert heat energy to, make the recording layer of CD produce changes in optical properties, thereby meet the reflectivity requirement of CD specification (Red Book), so the main light absorption wavelength of recording layer organic material must be avoided the main absorption region of laser.From the nineties, answer the constantly trend of expansion of data content, each big disc manufacturing plant merchant is main developing direction with the recording density that improves CD invariably, its main improved procedure is to be striving direction to dwindle recording track (pit) and track space, and when recording track and track space dwindle, dwindle the laser beam that is applied to read output signal, with the interference (cross-talk) of avoiding the interorbital signal and the resolution that improves recording track length, thereby the direction of optical maser wavelength toward 650nm and 635nm developed.Rule of thumb, if will use the wavelength of 650nm and 635nm, the preferred values of the light absorption wavelength of organic recording layer is between the 530nm to 600nm in the recordable optical recording media system.
JP 2640219 (Tokyo electrical equipment chemistry Industrial Co., Ltd) discloses cyanine dye has been applied in the optical recording media, but because the restriction of dyestuff chemistry structure, its disclosed optical recording media has in the medium of low recording density only for being applicable to the 780nm access system.
Summary of the invention
The object of the present invention is to provide a kind of high-density optical recording media, is the access system of 650nm and 635nm can be applicable to optical maser wavelength.
For achieving the above object, high-density optical recording media of the present invention comprises a base material, deposits a recording layer on this base material, and this recording layer comprises at least aly having by the represented laser absorption dyestuff of following formula (I):
Wherein Q is a phenyl ring, R
1, R
2Be C
1-8Alkyl, Y are C
1-4Alkoxy or hydrogen, X
-It is a negative ion.
High-density optical recording media of the present invention, its recording layer be the laser absorption dyestuff of free style (I) expression preferably, and wherein Q is a phenyl ring; R
1Be methyl, ethyl, propyl group or butyl; R
2Be butyl; Y is a hydrogen; And X
-Be the hexafluoro-phosphate radical negative ion.
High-density optical recording media of the present invention, its recording layer it is desirable to especially comprise and are selected from the following laser absorption dyestuff one or more:
2-(3 '-(1 ", 3 ", 3 "-trimethyl-6 "-methoxyl-benzo [e] indoles)-propenyl)-1,3,3-trimethyl-6-methoxyl-benzo [e] indyl perchlorate;
