The invention relates to anthraquinone polysulfonamide colorants derived from colored disulfonyl chlorides containing anthraquinone chromophores by reacting with various diamines. The anthraquinone polysulfonamide colorants are useful for coloring a wide variety of products such as plastics, fibers, films, cosmetics, skin creams or lotions, polishes, waxes, hair colorations, coatings, paints, inks, etc. and are particularly useful in end uses where sublimation, migration, extraction and exudation of presently used colorants are problems.

Anthraquinone polysulfonamide colorants

The present invention relates to a black polymeric composition suitable for use in films, fibers and molded articles, where a soluble, easily dispersed colorant is desirable. The black polymeric composition provides a high black color quality and is small enough to function as a black colorant in microdenier fibers. The black polymeric composition comprises a thermoplastic resin in an amount between about 50 weight percent and about 99.9 weight percent of the black polymeric composition, and a black dye composition in an amount between about 0.1 weight percent and about 50 weight percent of the black polymeric composition. The black dye composition contains a black indanthrone compound as a major component. As used herein, black indanthrone compounds are defined as compounds having the general structure represented by Formula I: ##STR1## wherein R is hydrogen or at least one group independently selected from C.sub.1 -C.sub.8 alkyl, C.sub.1 -C.sub.8 alkoxy, halogen, hydroxy, trifluoromethyl, aryloxy, arylthio, arylamino, C.sub.1 -C.sub.8 carbalkoxy, --CO.sub.2 H, C.sub.1 -C.sub.8 alkanoyloxy, arylazo, --CN, --NO.sub.2, --SO.sub.2 --C.sub.1 -C.sub.8 alkyl, --SO.sub.2 N(R1)R2, and --CON(R1)R2, wherein R1 and R2 are independently selected from C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.8 cycloalkyl, aryl and hydrogen. The present invention further relates to a process for preparing the black polymeric composition, processes for preparing the black dye composition and articles formed from the black polymeric composition.

Thermoplastic polymer compositions containing black dye compositions

This invention relates to new blue anthraquinone colorants having Formula I ##STR1## wherein R and R1 are the same or different and are selected from hydrogen and unsubstituted or substituted C1-C6 alkyl, C3-C7 cycloalkyl 2-furyl, 2-thienyl, or phenyl; R2 is aryl; X is a group selected from hydroxy, C1-C6 alkanolyloxy, carboxy, C1-C6 carbalkoxy and carbamoyloxy. The colorants are useful for copolymerizing into polymers such as polyesters and polyurethanes. In particular, they are advantageous for preparing colored sulfopolyesters which are useful for coloring human hair.
