  • Patent number: 7316890
    Abstract: Indolestyryl compounds and use thereof for a high density recording media and method for fabricating the same. The indolestyryl compounds exhibit strong absorbance in the visible light region (400˜700 nm) of the spectrum, resistance to heat and light, high light sensitivity, and excellent solubility, resulting from their special chemical configuration. Furthermore, the indolestyryl compounds can be used as recording layer materials in high density recording media for matching a reading laser wavelength and enhancing the reflective index and carrier-to-noise ratio (CNR) of the high density recording media. Accordingly, the recording sensitivity and the readout characteristics of high density recording media comprising the indolestyryl compound according to the present invention can be improved.

  • Patent number: 6761952
    Abstract: This invention provides imin complex dyes for a high-density optical disc recording medium having the following formula (I): wherein Y constitutes oxygen atom, sulfate atom, carbon atom with substitutes (C—R5) or nitrogen atom with substitutes (N—R6); R1 constitutes alkyl group having carbon number one to eighteen with or without substitutes or ether group, p-alkyl benzyl group with or without substitutes; R2, R3, R5, R6, R7 can be same or different groups; and X constitutes halogen atom, ClO4−, BF4−, PF6−, SbF6−, TCNQ−, TCNE−, naphthalenesulfonic acid or organometallic complex.x. The bis-styryl dyes whose spectra maximum absorption in visible light range of wavelength of 300 nm˜800 nm can be used as a high density optical disc recording medium.
