In this paper a novel, simple method for synthesis of lake pigments based on 1,2-dihydroxyanthra-quinone dye and LDH carbonates was proposed. LDHs were modified with 1,2-dihydroxyanthraquinone,transforming the soluble dye into a new kind of hybrid lake. In result, the solvent resistance andphotostability of the chromophore were improved, which may be attributed to strong dye–LDHinteractions. TOF-SIMS technique was used for thefirst time to confirm the role of C14H7O4Mg+ andC14H6O5Al ions in the formation of the hybrids. Alizarin lakes have been recognized as a new class ofcolorants which demonstrated good color characteristics and chemical stability.
