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.

Abstract: ISOINDOLINE DERIVATIVES ASYMMETRICALLY DISUBSTITUTED IN THE 1- AND 3-POSITION CORRESPONDING TO THE GENERAL FORMULA

1-R1,3-R2-ISOINDOLINE

IN WHICH THE CYCLIC RADICAL R IS AN AROMATIC RING, A SUBSTITUTED AROMATIC RING, A TETRAHYDROGENATED AROMATIC RING, A NITROGEN-CONTAINING HETEROCYCLIC RING, OR A SULPHUR-CONTAINING HETERCOYCLIC RING AND R1 AND R2 WHICH ARE DIFFERENT ARE BIVALENT RADICALS OF A COMPOUND WHICH CONTAINS TWO ACTIVE HYDROGEN ATOMS ATTACHED TO A CARBON OR NITOGEN ATOM AND A TWO-STAGE PROCESS FOR MAKING THE SAME. THE ISOINDOLINE DERIVATIVES ARE EXCELLENT DYESTUFFS FOR DYEING AND PRINTING SYNTHETIC FIBER MATERIALS.
