Abstract
Colored ink useful within an ink-jet printing device is disclosed. The ink is comprised of specifically disclosed yellow dyes, magenta dyes and cyan dyes within an aqueous ink composition. The use of the specific dyes within the aqueous ink composition prevents clogging within the nozzle of the ink-jet printer during operation or after operation has been restarted after a suspension of use of the printer. The ink composition has a high light-fastness characteristic, is not easily discolored by exposure to light and produces faithful color reproduction.
