Publication number: 20030083407Abstract: Colorants comprising a chromophore having two methine moieties attached to a benzodifuranone backbone, wherein said moieties optionally have at least one poly(oxyalkylene) chain, preferably at least two such chains attached thereto are provided. Such colorants exhibit excellent thermal stability, effective colorations, excellent low extraction rates, and effective lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain substrates, particularly polyesters. The optional poly(oxyalkylene) chains also increase the solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or on diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as are methods for producing such inventive colorants.Type: ApplicationFiled: September 18, 2001Publication date: May 1, 2003Inventors: Daniel M. Connor, Eric B. Stephens
