Abstract
An ink set for ink-jet recording is characterized in that, when a patch of each of an yellow dye ink, a magenta dye ink, a cyan dye ink and a black dye ink is subjected to an ozone resistance test, the OD value reduction ratios of the patches upon the ozone resistance test are such that the order of the OD value reduction ratios of the yellow, magenta and cyan components in the black dye ink patch is the reverse of the order of the OD value reduction ratios of the yellow component of the yellow dye ink patch, the magenta component of the magenta dye ink patch and the cyan component of the cyan dye ink patch.
