  • Patent number: 6248816
    Abstract: The present invention relates to a polymeric composition suitable for use in films, molded articles and fibers, including microdenier fibers. The polymeric composition comprises a thermoplastic resin in an amount from about 50 weight percent to about 99.9 weight percent of the polymeric composition, and a dye composition in an amount from about 0.1 weight percent to about 50 weight percent of the polymeric composition. The dye composition contains an indanthrone compound as a major component.
    Type: Grant
    Filed: May 11, 1999
    Date of Patent: June 19, 2001
    Assignee: Eastman Chemical Company
    Inventors: Max Allen Weaver, Clarence Alvin Coates, Jr., Jean Carroll Fleischer, Brian Edison Maxwell
  • Patent number: 6140517
    Abstract: 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.

  • Patent number: 5973038
    Abstract: 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.

  • Patent number: 5955564
    Abstract: 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.
