    Abstract: REACTIVE DYESTUFFS HAVING THE GENERAL FORMULA 1

    (AQ-CH2-NH-CO-CH2-N(-R'')-CO-R-X)(-SO3H)N

    ARE PRODUCED BY REACTING AN ANTHRAQUINONE DYESTUFF WHICH COMBINES THROUGH AN N OR O ATOM WITH EITHER A REACTIVE AROMATIC NUCLEUS HAVING A REPLACEABLE HYDROGEN, REPRESENTED BY THE GENERAL FORMULA 2

    Y-CH2-NH-CO-CH2-N(-R1)-CO-R-X

    OR WITH A REACTIVE AROMATIC NUCLEUS HAVING A REPLACEABLE HYDROGEN, REPRESENTED BY THE GENERAL FORMULA 3

    NH2-CO-CH2-N(-R'')-CO-R-X

    IN COMBINATION WITH FORMALDEHYDE OR A COMPOUND WHICH FORMS A FORMALDEHYDE. THE PRODUCT MAY BE SULFONATED, IF DESIRED.

    Abstract: NOVEL FIBER-REACTIVE ACID ANTHRAQUINONE DYESTUFFS ARE PROVIDED. SUCH NOVEL DYESTUFFS ARE PRODUCED BY COVERTING AMINO ANTHRAQUINONE DYESTUFFS INTO THE VALUABLE NOVEL DYESTUFFS BY THE INTRODUCTION OF HALOGEN, ACYLAMINO METHYL GROUPS. THE NOVEL DYESTUFFS ARE ESPECIALLY USEFUL FOR THE BATCH DYEING AND PRINTING OF FIBER MATERIAL CONTAINING POLYAMIDE, ESPECIALLY WOOL. THE INVENTION ALSO PROVIDES, AS INDUSTRIAL PRODUCTS, THE MATERIALS DYED AND PRINTED WITH THE NOVEL DYESTUFF.

    Abstract: Modified dyes, inks containing modified dyes, and associates methods of manufacture are described. The modified dyes are made by adding a hydrocarbon chain to the unmodified dyes through a hydroxyl, amine, or phenolic functional group. The modification is accomplished using compounds containing reactive groups selected from acid chlorides or halogenated hydrocarbon chains. The modified dyes provide enhanced water fastness and increased dispersibility of the dyes and associated inks.

    Abstract translation: 描述了改性染料，含有改性染料的油墨和缔合体的制造方法。 改性染料是通过羟基，胺或酚官能团向未改性染料中加入烃链而制成的。 使用含有选自酰氯或卤代烃链的反应性基团的化合物进行改性。 改性染料提供增强的耐水性和增加染料和相关油墨的分散性。
