Abstract

A dye composition, which comprising: (a) an azo dye of the formula (I) wherein R, R1, R2, R3 and Y are defined the same as the specification; and (b) an azo dye of the formula (II) wherein R, R1, R2 and Y are defined the same as the specification. These kinds of dye composition with good stability and build-up. The dye composition are suitable for dyeing and printing of materials containing either cellulose fibers, such as cotton, viscose rayon, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon etc. Dyed materials with excellent properties can be obtained, showing especially outstanding performance in of wash-off, build-up, level-dyeing, wet fastness, ghosting fastness and light fastness.
