The present invention relates to laundry care compositions comprising carboxylate dyes. The laundry care compositions can be laundry detergent compositions, laundry additive compositions such as fabric enhancer compositions or bleach additive compositions. Preferably, the laundry care composition is a laundry detergent composition. The composition can be a solid, such as a powder, tablet or bar, or a liquid. The composition can be in the form of a unit dose, such as pouch. Suitable unit dose pouches include single compartment and multi-compartment pouches.

Provided is a compound capable of accelerating the enzymatic reaction catalyzed by peroxidase. The present invention provides a peroxidase reaction accelerating agent comprising a compound represented by formula (I) and a method for measuring hydrogen peroxide using the same.

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.

A coloring composition for a color filter, a method of manufacturing the same, and a color filter for an image sensor manufactured using the coloring composition for a color filter are provided. The coloring composition includes a coloring composite including: a nanoparticle including a metal oxide or a non-metal oxide; and a colorant adsorbed on a surface of the nanoparticle, wherein the colorant includes one selected from a perylene compound including a carboxyl group (COOH) at the para position of a benzene ring, a diketopyrrolopyrrole compound including a carboxyl group (COOH) at the para position of a benzene ring, and an azo compound including a carboxyl group (COOH) at the para position of a benzene ring.
