  • Cathodic electrodeposition paint containing a vinylpyrrolidone copolymer
    Patent number: 8426500
    Abstract: An aqueous coating composition comprising (A) at least one water-dispersible organic binder containing cationic groups and (B) 0.05%-10% by weight, based on the solids content of the aqueous coating composition, of a water-thinnable vinylpyrrolidone copolymer, where the vinylpyrrolidone copolymer (B) contains vinylpyrrolidone monomer units and vinyl acetate monomer units in a molar ratio of 0.3:0.7 to 0.7:0.3, preferably of 0.4:0.6 to 0.6:0.4 and possesses a weight-average molecular weight of less than 200 000 g/mol.

  • CATHODIC ELECTRODEPOSITION PAINT CONTAINING A VINYLPYRROLIDONE COPOLYMER
    Publication number: 20110100824
    Abstract: The invention relates to an aqueous coating composition containing (A) at least one organic binder that can be dispersed in water and contains cationic groups, and (B) 0.05-10 wt. %, in relation to the solid body content of the aqueous coating composition, of a water-dilutable vinylpyrrolidone copolymer. Said vinylpyrrolidone copolymer (B) contains vinylpyrrolidone monomer units and vinylacetate monomer units in a molar ratio of 0.3:0.7-0.7:0.3, preferably 0.4:0.6-0.6:0.4 and has an average molecular weight of less than 200.000 g/mol.
