| titleOfInvention | Lake pigment preparation method, lake pigment and application thereof |
| abstract | The present application belongs to the technical field of lake pigments and relates to a lake pigment preparation method, a lake pigment and an application thereof. The lake pigment preparation method of the present application comprises the following steps: adding a solution containing at least two metal ions to an acidic dye solution containing a pigment raw material to obtain a solution A; and adding a chelating agent to solution A so as to carry out a chelation/complexation reaction at a pH value of ≥ 8 to obtain a pigment lake. The method of the present application is simple and easy to execute, and achieves convenient adjustment of the color or color phase difference of a pigment lake. The prepared pigment lake has a small particle size, high tinting strength, improved heat resistance, excellent acid and alkali resistance, as well as excellent light resistance, thereby broadening the application range of pigment lakes. |
