CYANINE COLORING MATTER AND OPTICAL RECORDING MEDIUM

摘要

This invention provides a novel organic compound, which absorbs short-wavelength visible light, has excellent lightfastness and solubility in solvents, and has heat characteristics depending upon applications to which the organic compound is applied. The organic compound can broaden the width of organic compounds, which can be selected as a light absorbing material in a wide variety of applications including information recording, solar power generation, electrical machineries and apparatuses, electrical communication equipment, optical equipment, clothing materials, building and bedding products, healthy and hygienic goods, and agricultural materials, particularly optical recording media. The organic compound is a cyanine coloring matter having a specific structure.
