    摘要： IN WHICH T1 is H, phenyl, anisyl, NH2, or lower alkyl, T2 is H, CN, lower alkyl, CONH2 or substituted aminocarbonyl, Z is R, HOR''-, ROR''-, R2NR''-, phenyl or anisyl, (R and R'' are lower alkyl and lower alkylene) the diazo component carrying a cellulosereactive group. Also included are dyes in which the reactive group also contains an anthraquinone or phthalocyanine residue or where two moles of the dye are linked through a diamine radical. Cr and Co complexes of dyes in which the diazo component is a oaminophenol are included.
