摘要:
The invention is related to a weather-resistant dye and use thereof, which contains in molecules thereof not only chromophoric parent D, but also electron-accepting group Q which is linked with dye parent D through non-conjugated carbon link L to constitute D-L-Q dye molecule; the electron-accepting group Q has such a HOMO energy level that is lower than the HOMO energy level of the dye chromophoric parent D. The dye has sun-resistance and anti-ozone performances, which can be used as colorant in the ink, dope, lacquer, toner powder for laser printing, marker, paper, fabric, glass, porcelain or polymer.
