Abstract
The present invention is directed to polymer compositions containing a vinyl polymer component (A), formed by polymerization of .alpha.,.beta.-ethylenically unsaturated monomers, one which contains at least one hydroxyl group and one which contains no hydroxyl groups; a crosslinker component (B); an additive component (C); and a solvent component (D). The composition is useful for backcoating woven substrates and as a binder composition for non-woven substrates.
