WIPO Patent Application WO/2005/092988
Kind Code:
A1
Abstract:
A cyanine pigment which has a specific structure and exhibits a main local maximum in the absorption spectrum thereof at a wave length longer than 400 nm, in the state of a liquid. The cyanine pigment absorbs a visible light having a short wave length, is excellent in the resistance to a light and the solubility to a solvent, and, in addition to the above, also has thermal characteristics meeting requirements of new fields wherein organic pigment compounds are applied, which results in the expansion of the width of organic pigment compounds capable of being selected as a light absorbing material in the above-mentioned fields.
