    Abstract: Dyestuffs with pigment properties are obtained, by acylating dyestuffs of the anthraquinone and anthraquinoid series which have at least one amino or mercapto group with tetrabromo- or tetrachloro-benzthiazoles or benzoxazoles which are substituted in the 2-position with an anionic leaving-group. Subject of the invention are furthermore the acylation reagents 2chlorotetrabromobenzthiazole and 2-chlorotetrabromobenzoxazol, which are manufactured by chlorination of benzthiazol, respectively benzoxazol in the 2-position and subsequent bromination of the benzene nucleus.
