Easily dispersible formulations of pigments and their use in tinting base media |
摘要 |
Formulations of easily dispersible (ED) pigments comprising a combination of a carboxylic acid polymer and a non-ionic alkoxylated surfactant are disclosed. The combination is used in the formulation of a plurality of pigments. The formulations are suitable for mixing with a base medium at the point-of-sale (PoS) or by the end user. |

1. A method of preparing a flowable particulate formulation for use in the tinting of base media comprising the step of spray drying an aqueous dispersion of a mixture with a total solids content of 45 to 75% (w/w) comprising a plurality of pigments, a polycarboxylic acid and a non-ionic alkoxylated surfactant where the ratio by weight (w/w) of formulant to total pigment is in the range 1.4 to 11.3% polycarboxylic acid and 4.5 to 37.7% non-ionic alkoxylated surfactant. |
