摘要： A family of 1:2 Fe-complexed formazan dyes is described. The dyes unexpectedly afford reddish-violet, violet, blue and black shades on natural and synthetic substrates. Methods for synthesizing the dyes and for dyeing a substrate are described. The dyes represent environmentally friendly alternatives to conventional Cr- and Co-based azo and formazan dyes.

摘要： Nonmutagenic, highly twisted derivatives of benzidine of the following formula ##STR1## useful as intermediates for the preparation of various organic pigments were obtained. The benzidine derivatives are significantly rotated about the biphenyl linkage due to bulky substituents at the R.sub.2 and/or R.sub.4 positions. Bisazomethine, disaoacetoacetanilide, disazopyrazolone, disazobenzimidazolone and disazonaphthol pigments prepared from these highly twisted benzidines exhibit hypsochromic spectral shifts relative to pigments prepared from other benzidine compounds with less twist about the biphenyl linkage, for instance, other benzidine compounds in which all four R.sub.2 and R.sub.4 represent H. Greenish-yellow, yellow, orange, red and brown pigments obtained from the twisted benzidines are nonmutagenic in the standard Ames test and Prival modification.

摘要： Disclosed is an original approach to solving the environmental problem associated with the use of Cr-based metallized azo dyes to deliver black shades on natural and synthetic substrates. This invention affords methods for both the synthesis of metallized dyes and the generation of black dyeings using those dyes without employing metals designated as priority pollutants at any stage in either method. The key element of the disclosure is the use of black 1:2 Fe complexes of azo dyes in lieu of currently used Cr-based complexes which are based on environmentally unfriendly priority pollutant metals without compromising the desirable high fastness properties of the latter complexes, an accomplishment heretofore assumed unachievable.

摘要： Functionalizing a fibrous material having a plurality of hydroxyl groups includes reacting the fibrous material with a compound of Formula I: where X is a monovalent counteranion for the quaternary ammonium cation of Formula I and Hal is a halogen atom, to obtain the functionalized fibrous material. Also provided is a functionalized fibrous material prepared by any one of the methods described herein (e.g., a functionalized fiber including a moiety of Formula II: having an odor of free amine below the threshold of detection, or having an odor of free amine with degree of offensiveness of about 3 or less. The functionalized fibrous material may be dyed, and articles of clothing may be made from the dyed functionalized fibrous material.

摘要： The presently disclosed subject matter relates to heterobifunctional reactive dyes comprising nitrogen-containing heterocycles substituted by both halogen and vinyl sulfone moieties. In particular, the presently disclosed subject matter relates to reactive dye compounds comprising two or more halo-substituted, nitrogen-containing heterocycles and an asymmetric bridging group, wherein at least one of the two or more halo-substituted, nitrogen-containing heterocycles further comprises a vinyl sulfone substituent. In some embodiments, the bridging group has a structure based on cysteamine or cysteine. The heterobifunctional reactive dyes have high substrate affinity and can be applied to substrates, such as cotton fibers, under low salt conditions and with reduced dye material waste.
