Migration-resistant binder compositions for bonding nonwoven fibers are disclosed. These compositions comprise (A) an anionically-stabilized polymer latex; (B) a water-soluble polymer of 20-100% by weight of mer units containing an amine group and having a viscosity average molecular weight between 5,000 and 300,000; (C) a volatile base and (D) 0 to 80% of pigment based on the total polymer weight of (A) and (B). Usually, the compositions have a solids content between 10% and 60% by weight, a viscosity below 3,000 centipoise, a pH above 5, and a component (B) content between 0.1% and 20% by weight of the solids. In alternative compositions, component (B) is replaced by component (B'), a water-insoluble polymer with the same amine group content and a viscosity average molecular weight between 5,000 and 100,000. (A), (B) and (B') are polymers of a .alpha.-.beta. ethylenically unsaturated monomers.
