Claim 2:
3. The mixer system as claimed in claim 1, wherein the nonionically stabilized binder (a-3) of the pigment paste A is a nonionically stabilized acrylate copolymer in dispersion in water, the nonionically stabilized acrylate copolymer being obtainable by reaction of
(I) at least one anchor group monomer unit having at least one ionizable functional group, a functional group with active hydrogen, or a combination thereof, wherein
the ionizable functionality is other than a carboxylic acid group in which the carbonyl carbon is separated from the closest ethylenically unsaturated carbon by at least four atoms,
the anchor group of monomer units (a) contain no polyoxyalkylene groups, and
one of the anchor group monomer units is copolymerized 1-(2- methacryloyloxyethyl)-2-imidazolidinone;

(II) 5 wt % to 45 wt %, based on the total weight of the monomers, of at least one monomer unit comprising a polyoxyalkylene group, a gamma-hydroxycarbamate group, a beta-hydroxycarbamate group, and a combination thereof; and
(III) 1 to 50 weight percent, based on the total weight of the monomers, of at least one aromatic monomer unit.
