  • Aqueous polymer dispersions
    Patent number: 5712339
    Abstract: An aqueous polymer dispersion containing polymer particles formed of at least two polymers, the polymer particles of the dispersion having a minimum film-forming temperature below 60.degree. C. and being formed of two different polymers namely polymer A having a glass transition temperature (T.sub.gA) of not more than 10.degree. C., and forming from 5 to 65% by weight of the total polymer; and polymer B having a glass transition temperature (T.sub.gB) of more than 25.degree. C., and forming from 5 to 65% by weight of the total polymer; together with a multifunctional material (C) present in an amount of from 5 to 70% by weight of the total polymer system.
