(DE) BIS-AZO-FARBSTOFFE ZUR VERWENDUNG ALS BLAUFÄRBEMITTEL
(EN) BIS-AZO COLORANTS FOR USE AS BLUING AGENTS
(FR) COLORANTS DIAZO UTILISÉS COMME AGENTS D'AZURAGE
Abstract
(EN)
This invention relates to bis-azo colorants for use as bluing agents, laundry care compositions comprising bis-azo colorants that may serve as bluing agents, processes for making such bluing agents and laundry care compositions and methods of using the same. The bluing agents are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. These bluing agents are advantageous in providing a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics.

(FR)
L’invention concerne des colorants diazo utilisés comme agents d'azurage, des compositions de blanchisserie comprenant des colorants diazo susceptibles de servir d’agents d'azurage, des procédés de fabrication des agents d'azurage et des compositions de blanchisserie et des procédés d'utilisation de ceux-ci. Les agents d'azurage sont généralement constitués d'au moins deux composants : au moins un composant chromophore et au moins un composant polymère. Ces agents d'azurage permettent de produire un effet de blanchiment des textiles, sans accumulation au fil du temps et sans produire une décoloration bleue non voulue des textiles traités.
