A dye composition, comprising (A) at least one disazo dye selected from the formula (I) or (II), wherein R, R, R, Dand Dare defined as in the specification; and (B) a diazo dye of the formula (III), wherein (R), (R), Qand Qare defined as in the specification. These dye compositions have high fixation and good build-up. They are distinguished also by high washing off and low nylon staining and they are suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or polyamide fibers, such as wool, silk, and nylon etc. Dyed materials with excellent properties can be obtained, showing especially outstanding performance in washing off, levelness, build-up, wet fastness and light fastness.
