<P>PROBLEM TO BE SOLVED: To provide an optical recording medium which makes good recording and reproducing possible with a laser of a wavelength 300 to 500 nm, or a colored resin composition which can cut UV rays and visible rays with a single dyestuff without using dark color-system coloring agents, has excellent optical stability and can maintain sufficient coloring for a long period, a dark color- system ink composition and a dark color-system molding and colored substrate using these composition. <P>SOLUTION: The optical recording medium formed by selecting at least ≥1 kind of compound from fullerene components and incorporating the compound into a recording layer, the colored composition containing the fullerene dyestuff into the base material, the ink composition containing the fullerene dyestuff, the colored lens subjected to coating consisting of this ink composition and the colored lens deposited by evaporation with the fullerene dyestuff on the surface. <P>COPYRIGHT: (C)2003,JPO |
