Abstract

The invention discloses a colorant composition and a method. The compositions of the present invention include rare earth sulfides, alkaline earth metal oxides, alkali metal hydroxides and alkali metal bicarbonates. By mixing alkaline earth metal oxides, alkali metal hydroxides and alkali metal bicarbonates with rare earth sulfide colorants, it can significantly inhibit the rare earth sulfide colorants from producing hydrogen sulfide gas in water, and the concentration of hydrogen sulfide gas can be controlled at 0.02ppm As a result, the harm of hydrogen sulfide gas to the environment and human body is greatly reduced, and the application range of rare earth sulfide colorants is broadened.

Description

Technical field[0001]The invention relates to a colorant composition and a method, in particular to a colorant composition containing a rare earth compound and a method for improving the stability of the colorant.Background technique[0002]Γ-Ln represented by lanthanum sulfide and cerium sulfide2S3The colorant is bright, strong coloring power, good heat resistance, good light resistance and good weather resistance, so it has the advantages of both organic and inorganic pigments. In addition, γ-Ln2S3The colorant does not contain heavy metal elements, and is currently an internationally recognized new generation of inorganic colorant replacement products. The colorant can replace toxic pigments such as cadmium red and lead red, so it has a huge market prospect. γ-Ln2S3The colorant can be synthesized by CN102127317A, CN102120602A and other methods.[0003]In order to expand its application range, Ln2S3The stability of the colorant still needs to be further improved. In lanthanum sulfide, ...
