Patent number: 8629207Abstract: An aqueous coating formulation for tannin-containing substrates can include a substituted C2-C4 polyalkyleneimine. Reacting a C2-C4 polyalkyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative can produce the substituted polyalkyleneimine. The carboxylic acid derivative includes at least one C1 to C30 alkyl group or C3 to C30 alkenyl group. Substrates that contain tannin and are coated with this aqueous coating formulation exhibit outstanding resistance with respect to color runs and color strikethrough.Type: GrantFiled: December 15, 2010Date of Patent: January 14, 2014Assignee: BASF SEInventors: Audrey Cosyns, Arno Tuchbreiter, Robert Feuerhake, Jörg Nieberle
