| abstract |
The present invention relates to a composition comprising at least one oxonol dye and at least one metal complex of the formula (I-1) or (I-2), a recording medium containing the composition, an optical recording medium, a color filter, and It relates to the use of the composition in the manufacture of printing inks (substituents as defined in the description). The use of the metal complex of formula (I) surprisingly weakens the tendency of the oxonol dyes to aggregate in the solid state and the absorption curve remains advantageously narrow even in the solid state, so that the desired spectrum is obtained. A recording medium having high reflectance and high sensitivity in the range and good reproduction characteristics can be used. |
