DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monoazo dye for polyester fibers, and more specifically, it dyes polyester fibers in red to blue colors that are excellent in various degrees of rigidity, particularly light resistance and sublimation resistance. The present invention relates to a monoazo dye having excellent heat resistance and alkali discharge printing resistance.

Recently, as a new dyeing process for polyester fibers, alkali-resistant discharge printing has become popular. The principle of alkali-proof discharge printing is to hydrolyze the dye in a predetermined portion of the dyed fabric with an alkali, causing it to lose its affinity for polyester fibers.
