| Zusammenfassung: | The invention provides a photoabsorption pigment, which has a good photoabsorption property to the light with a wavelength of 800-1100nm. The light has a energy of absorption which will not decrease in a large scale with time and has a big solubility to the solvent. The photoabsorption pigment comprises a substituted phenyl dithiol metal coordinated compound anion represented by the general formula (1) and an ion pair combination of the cyanine pigment cation represented by the general formula (2) (the specification of the symbol is the same as the recordation in the specification). A photoabsorption material is obtained by coating the photoabsorption pigment on the base board. |
