Abstract
Abstract Use of anthraquinone derivatives of the formula ##STR1## wherein X is --NH-- or --S--, one Y is --NHCOR, R being an alkyl, aryl or heterocyclic residue, the other Y are hydrogen, Z is halogen, and n is 0, 1, 2 or 3, whereby Z may be 1 to 3 halogen bound to aryl and/or anthraquinone nucleus and/or the residue R, for dyeing polyesters in the melt.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
A process for dyeing polyesters in the melt, by intimately mixing with said polyester in the melt, an anthraquinone derivative of the formula ##STR14## wherein R 1 is hydrogen, halogen, alkyl or alkoxy having 1-4 C atoms, and R 2 and R 3 are hydrogen, halogen or alkyl having 1-4 C atoms, with R 2 and R 3 being hydrogen if R 1 is alkoxy, X is an --NH-- group or an --S-- atom, one Y is the radical of the formula --NHCOR and the other two Y groups are hydrogen, with R being alkyl having 1-4 C atoms, a mononuclear five- or six-membered heterocyclic radical or a radical of the formula ##STR15## in which R 4 is hydrogen, halogen, hydroxyl, alkyl or alkoxy having 1-4 C atoms, phenyl or phenoxy, R 5 is hydrogen, halogen or alkyl having 1-4 C atoms and R 6 is hydrogen or halogen, with R 6 being halogen if R 4 is halogen or alkyl, Z is halogen and n is O, 1, 2 or 3, and 1-3 Z's can be bound as substituents R 1 to R 3 and/or as substituents on the anthraquinone nucleus or on the radical R.
Claim 2
Dependent Claim
197 words
A process for dyeing polyesters in the melt, by intimately mixing with said polyester in the melt, an anthraquinone derivative of the formula ##STR14## wherein R 1 is hydrogen, halogen, alkyl or alkoxy having 1-4 C atoms, and R 2 and R 3 are hydrogen, halogen or alkyl having 1-4 C atoms, with R 2 and R 3 being hydrogen if R 1 is alkoxy, X is an --NH-- group or an --S-- atom, one Y is the radical of the formula --NHCOR and the other two Y groups are hydrogen, with R being alkyl having 1-4 C atoms, a mononuclear five- or six-membered heterocyclic radical or a radical of the formula ##STR15## in which R 4 is hydrogen, halogen, hydroxyl, alkyl or alkoxy having 1-4 C atoms, phenyl or phenoxy, R 5 is hydrogen, halogen or alkyl having 1-4 C atoms and R 6 is hydrogen or halogen, with R 6 being halogen if R 4 is halogen or alkyl, Z is halogen and n is O, 1, 2 or 3, and 1-3 Z's can be bound as substituents R 1 to R 3 and/or as substituents on the anthraquinone nucleus or on the radical R.
