    摘要: The present invention provides a dye composition suitable for forming an information recording layer for carrying out recording and readout with laser beams, which includes at least one compound of formula (I): where n is selected from the group consisting of integer 0˜3; B represents boron; O represents oxygen; X1 and X2 are individually selected from the group consisting of oxygen and fluorine; Y is selected from the group consisting of alkoxyl, alkoxycarbonyl, phenylcyclo having substituent, phenylcyclo having non-substituent, a heterocyclic structure having boron, nitrogen, oxygen, sulfur and selenium (which is composed of Y and Z); Z is selected from the group consisting of hydrogen, alkoxyl, cyanogen radical, the heterocyclic structure having boron, nitrogen, oxygen, sulfur and selenium (which is composed of Y and Z); R is selected from the group consisting of alkoxyl, amino, phenylcyclo having substituent, phenylcyclo having non-substituent, ferrocenyl, a heterocyclic structure having boron, nitrogen, oxygen, sulfur and selenium. The dye composition has strong absorbance (ε≧104 cm2/mole) for the ultraviolet light and the visible light region, it is therefore that the dye composition is suitable for forming an information recording layer of the optical recording medium. Further, the dye composition is also suitable for FMD-ROM/FMD-R because of the high fluorescent quantum efficiency.
