Abstract
Aqueous dispersion of polymer particles comprising at least one first polymer and at least one second polymer which are mutually incompatible. The first polymer is non-crosslinked, has a glass transition temperature of from -25.degree. to 0.degree. C. and represents from 40 to 65% by weight of the particles; the second polymer is not alkali-soluble and is non-crosslinked, has a glass transition temperature of from 5.degree. to 40.degree. C. and represents from 60% to 35% by weight of the particles; the glass transition temperature of the second polymer exceeds that of the first polymer by less than 40.degree. C. and the average particle size is between 100 and 300 nm. Application to the production of environmentally compatible paints.
