  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.

  本申请涉及噻吩偶氮羧酸酯染料作为色调剂的用途，包括含有此类染料的洗涤保养组合物可作为色调剂，制备此类染料和洗涤保养组合物的方法以及使用它们的方法。前述染料含有一个形式上带电的基团，通常由至少两个组分组成：至少一个色团组分和至少一个聚合物组分。适当的色团组分通常在紫外光下照射时发出蓝色、红色、紫色或紫色的荧光，或者它们可以吸收光线以反射这些相同的色调。这种染料在提供色调效果方面具有优势，例如，对织物具有美白效果，同时不会随着时间的推移而积累并导致处理过的织物产生不良的蓝色变色。此类染料通常也稳定于洗涤保养组合物中使用的漂白剂。
