Abstract: The waterborne multicolor coatings have been prepared by the gelation reaction between the hydroxy of HEC and the metal cation of hectorite. Several factors including the type of emulsion and its dosage, the dosage of HEC and high-concentr protective glue solution, the type of additives and aqueous color paste affecting the bleeding resistant performance have been investigated and thus an optimized process for production of multicolor coatings showing good bleeding resistance and stability has been obtained.
