  • Publication number: 20150031591
    Abstract: This application relates to thiophene azo carboxylate dyes for use as hueing agents, laundry care compositions comprising such dyes that may serve as hueing agents, processes for making such dyes and laundry care compositions and methods of using the same. The aforementioned dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. Such dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. Such dyes are also generally stable to bleaching agents used in laundry care compositions.
