  • Cyanine dye
    Patent number: 8350015
    Abstract: An objective of this invention is to extend the range of choosing organic dye compounds as radiation-absorbing agents in a variety of fields by providing a novel organic dye compound which absorbs short-wavelength visible radiation and exhibits a superior in optical resistance, solubility in solvents, and heat characteristics required in a novel field in which the organic dye compound is applied: The objective is attainable by providing a cyanine dye which has a specific structure and exhibits a major adsorption maximum at a wavelength longer than 400 nm in a solution.

  • Optical recording medium
    Patent number: 5155009
    Abstract: An optical recording medium having a recording layer containing a particular cyanin coloring matter and a particular quencher. The material of the recording medium can be directly applied to the substrate without any damage to the substrate. The productivity of this recording medium is therefore high. This medium also has superior recording/reproduction characteristics.
