Title (EN) NOVEL FLUORINATED DYE STABILIZERS IN FLUORINATED DIELECTRIC SOLVENT
(FR) NOUVEAUX STABILISATEURS DE COLORANTS FLUORES DANS UN SOLVANT DIELECTRIQUE FLUORE
Abstract: front page image
(EN)The present invention is directed to novel fluorinated dye stabilizers having both high quenching efficiency and solubility in halogenated solvents. These dye stabilizers have shown a significantly effect on improving the dye fastness in hostile photooxidation conditions. Formula (I), wherein M is a metal ion, n is 2 or 3; formulae (II) and (III), wherein M’ is absent or a metal ion; formulae (IV), (V), (VI) and (VII), wherein M is a metal ion; n is 2 or 3; at least one of R1 and R2 is Rf-A-; A in Rf-A- is absent, oxygen or an alkylene chain; and Rf is a fluorinated alkyl or aryl or a low/medium molecular weight fluorinated polymeric or oligomeric moiety.
(FR)La présente invention concerne des nouveaux stabilisateurs de colorants fluorés présentant une efficacité d'extinction et une solubilité élevées dans les solvants halogénés. On a observé que ces stabilisateurs de colorants contribuent sensiblement à améliorer la solidité des colorants dans des conditions de photooxydation hostiles.
