ABSTRACT:
A monoazo dye for polyester fiber represented by formula ##STR1## and having a crystal modification characterized by an X-ray diffraction spectrum (CuK.alpha.) showing a very strong peak at an angle of diffraction (2.theta.) of about 14.2.degree., a strong peak at about 24.5.degree., and four weak peaks at about 16.9.degree., 23.6.degree., 25.3.degree., and 26.8.degree.. The monoazo dye exhibits excellent dispersibility to effect level dyeing even under high temperature and severe conditions and provides a dyed material excellent in light fastness and rubbing fastness, as well as wet fastness after post-finish.
