A dried film reinforced with coalescable water insoluble polymer particles which are substantially noncoalesced is disclosed. Also disclosed are dried films reinforced with noncoalesced water insoluble polymer particles which are readily water dispersible. Also disclosed are stable aqueous dispersions for formation of such films which comprise (a) a water insoluble component comprising coalescable polymer particles which have a T.sub.g less than 55.degree. C. and a majority of which have a particle size of less than 1 micron; and (b) a water soluble component which comprises a water soluble polymer capable of inhibiting coalescence of the polymer particles, or a water soluble polymer and a component capable of inhibiting coalescence of the polymer particles.
A coated paper comprising a substrate and a coating binder thereon wherein the coating binder comprises (a) a water insoluble component comprising noncoalesced coalescable polymer particles which have a T.sub.g less than 55.degree. C. and a majority of which have a particle size of less than 1 micron;
A method for coating a substrate comprising the steps of applying to said substrate a coating color composition comprising a pigment and a binder comprising a stable aqueous dispersion capable of forming, at about 70.degree. F., a film reinforced with coalescable water insoluble polymer particles, which particles are substantially noncoalesced, said dispersion comprising a water insoluble component and a water soluble component wherein:
