Said invention also relates to novel copolymers CP which are embodied in the form of polymers consisting of at least three types of different monoethylenically unsaturated monomers M and comprise, in the polymerisation incorporated form, a) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group, Pl) at least one type of neutral monoethylenically unsaturated monomer M2 whose water solubility at a temperature of 20 0C is less than 30 g/l and P2) at least one type of neutral monoethylenically unsaturated monomer M2b whose solubility at a temperature of 20 0C is greater than 50 g/l.
