POLYMERIC COMPOSITIONS USEFUL AS BINDERS IN COATING COLORS AND COATING COLORS PREPARED THEREFROM

摘要

The present invention relates to a polymeric binder composition comprised of two polymeric components wherein one of the two polymeric components is a lightly cross-linked copolymer comprising, in polymerized form, an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, an ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid and an unsaturated nitrile. In general, such cross-linking is achieved using a small amount of a cross-linking monomer such as allyl methacrylate.
