ABSTRACT:
The present invention relates to the product from the reaction of a basic polyaluminum or aluminum salt with an amino acid-based anionic surfactant. This agent is espectially effective for improving the chroma and brightness of pigments, even when such pigment is treated with the polyaluminum salt by mixing. In addition to this, the polyaluminum salt increases the lipophilic properties of the pigment, which improves their oil-dispersability and also prevents bleeding of the pigments.
