摘要: The invention relates to the use of particular phosphoric esters as emulsifiers and dispersants for pigments and fillers, based on polystyrene-block (b)-polyalkylene oxide copolymers. The invention provides block copolymeric phosphoric esters and their salts of the general formula (I) [R1O(SO)a(EO)b(CH2CHCH3O)c(BO)d]xPO—(OH)3−x (I) where R1=a straight-chain or branched or cycloaliphatic radical having 1 to 22 carbon atoms, SO=styrene oxide, EO=ethylene oxide, BO=butylene oxide and a=1 to
