Patent number: 5667885Abstract: 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.Type: GrantFiled: May 14, 1996Date of Patent: September 16, 1997Assignee: Penford Products CompanyInventors: Charles C. Nguyen, Verne J. Martin, Edward P. Pauley, Henry L. Buccigross, Stephen Rudolph
