    • Monoazo dyes for dyeing polyester fibers represented by the formula: wherein D represents a substituted or unsubstituted thiazolyl, benzothiazolyl, thiadiazolyl or pyridyl group, X represents a hydrogen atom, a chlorine atom, a methyl group, a methoxy group or an acylamino group, Y represents a hydrogen atom, a chlorine atom, a methyl group, an alkoxy group or an alkoxyalkyl group, R1 represents a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl or aryl group, and R2 represents a phenoxymethyl group, a phenoxyethyl group, a benzyl group or a tetrahydrofurfuryl group. Fibers which can be dyed with the azo dyes of the present invention include polyester fibers such as polyethylene terephthalate, a polycondensate between terephthalic acid and 1,4-bis (hydroxymethyl) cyclohexane or the like and blended or mixed fibers of the above-described polyester fibers with natural fibers such as cotton, silk or wool. The present dyes can also be used in combination with other dyes of the same series. In some cases, blending two or more dyes represented by the general formula (I) provides good results as well as an improvement of the dyeing properties.
