    Abstract: The invention relates to aqueous pigment preparations containing i) at least one copolymer P of ethylenically unsaturated monomers M in the form of an aqueous polymer dispersion which contains between 0.1 and 1.5 weight %, in relation to the total weight of the copolymer P, of polymerised itaconic acid as acid monomer M1, its salts and/or anhydride, where up to 50 weight % of the itaconic acid can be substituted by another monomer having at least one acid group or a neutralised acid group, and whose glass transition temperature TG lies between -10 and +50 ~C; ii) at least one inorganic pigment; iii) possibly inorganic fillers; and iv) standard additives. The invention also relates to the use of the copolymers P containing itaconic acid for improving the wetabrasion resistance of polymer-bound coatings containing pigments.

    Abstract: An aqueous latex coating composition and method of making an aqueous latex coating composition that comprises at least one oligomeric ethylene glycol derivative having the structure RO—(CH2—CH2—O—)n—H, at least one latex polymer, and water, wherein R is H or Cl-C4 alkyl and preferably H, and n is from 3 to 9, preferably from 3 to 8, and more preferably from 3 to 6. The oligomeric ethylene glycol derivative functions as both a coalescing solvent and freeze-thaw stabilizer without contributing to the VOC content of the composition.
