Title
(EN) NOVEL SHORT-CHAIN POLYMERIC YELLOW CYANOESTER-DERIVATIVE COLORANTS AND ARTICLES COMPRISING SUCH COLORANTS
(FR) NOUVEAUX COLORANTS JAUNES DERIVES DE CYANOESTER ET POLYMERES A CHAINE COURTE ET ARTICLES RENFERMANT DE TELS COLORANTS
Abstract
(EN) A yellow colorant comprising a chromophore having at least one poly(oxy-C2-C4-alkylene) chain attached to an aromatic methine backbone having at least one cyanoester moiety attached thereto is provided. The ester portion must include a C1-C8 (such as ethyl, butyl, hexyl, or ethyl-hexyl) pendant group and the poly(oxyalkylene) chain must be at most 10 monomers and at least 3 monomers, with ethylene oxide as the capping group. Such a specific group of coloring agents provides the best overall yellow colorations or effects (either alone or in blends with other coloring agents, particularly at low color loadings) as well as the best overall low extraction levels when present within clear polyester (such as polyethylene terephthalate, for example), when compared to all other known polymeric yellow colorants for the same end-use. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants.
(FR) L'invention concerne un colorant jaune comprenant un chromophore présentant au moins une chaîne poly(oxy-C2-C4-alkylène) fixée sur un squelette de méthine aromatique, au moins une fraction de cyanoester étant fixée sur celui-ci. La partie d'ester doit comprendre un groupe latéral en C1-C8 (tel que l'éthyle, le butyle, l'hexyle, ou l'éthyl-hexyle) et la chaîne poly(oxyalkylène) doit être constituée au maximum de 10 monomères et de 3 monomères au minimum, avec l'oxyde d'éthylène comme groupe de coiffage. Un tel groupe spécifique de colorants permet d'obtenir les meilleures colorations jaunes globales ou les meilleurs effets jaunes globaux (soit utilisé seul, soit dans des mélanges avec d'autres colorants, notamment à faibles charges de couleur), ainsi que les meilleurs faibles niveaux d'extraction globaux quand le groupe est présent dans un polyester clair (tel qu'un polyéthylène téréphtalate, par exemple), comparativement à tous les autres colorants jaunes polymères connus destinés à la même utilisation finale. L'invention concerne également des compositions et des articles renfermant de tels colorants, ainsi que des procédés de fabrication des colorants selon l'invention.
