    摘要: This invention relates to heterocyclic red azo colorants for seed treatment applications. The red azo colorants contain a heterocycle that includes one nitrogen atom and one sulfur atom and are free from electron-withdrawing groups on the heterocycle. Seeds for use in horticultural/agriculture applications that are coated with the heterocyclic azo colorants provide anti-counterfeiting properties to the coated seeds. A color change phenomenon is observed when the coated seeds are exposed to an acidic material, such as vinegar, and provides evidence of the authenticity of the coated seeds. The invention also relates to agricultural formulations containing the heterocyclic red azo colorants that can be used as an anti-counterfeit agents.

    摘要: The disclosure relates to a method for improving the alkali resistance and oxidation resistance of a benzothiazole disperse dye, and belongs to the field of disperse dyes. In the disclosure, 4 kinds of diazo components and 8 kinds of coupling components are used in designing and synthesizing 28 thiazole heterocyclic azo disperse dyes, and the alkali resistance and oxidation resistance of the disperse dyes are improved. Structure confirmation is performed on the synthetic disperse dyes, and the alkali resistance, oxidation resistance and other dyeing properties of the disperse dyes are tested. According to the method for improving the alkali resistance and oxidation resistance of the benzothiazole disperse dye provided in the disclosure, a relationship between a dye structure and the alkali resistance and oxidation resistance is determined, the disperse dyes with excellent alkali resistance and oxidation resistance are obtained, and the dyeing performance is stable under a dyeing condition of 10 g/L of sodium hydroxide or 5 g/L of hydrogen peroxide. This kind of dyes can be applied to a one bath for bleaching and dyeing of polyester and cotton and a one bath for deweighting and dyeing of polyester, dyeing and finishing in a short process are achieved, and great ecological and economic benefits are obtained.

    摘要: A pigment composition contains: an azo pigment that is a reaction product between a coupler and a base; and a pigment derivative, and a content of o-anisidine derived from the coupler is less than or equal to 20 mg/kg in the entire pigment composition. A method for producing the pigment composition includes, after reaction between a coupler and a base to generate an azo pigment, or during the reaction between the coupler and the base, adding a remover for o-anisidine derived from the coupler.

    摘要: 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.
