An aqueous polymer particle dispersion including at least one first polymer and at least one second polymer, which polymers are mutually incompatible. The first polymer is not cross-linked, it has a glass transition temperature of -25 to +0 DEG C, and it represents 40-65 wt % of the particles. The second polymer is neither alkali-soluble nor cross-linked, it has a glass transition temperature of 5 to 40 DEG C, and it represents 60-35 wt % of the particles. The second polymer has a glass transition temperature no more than 40 DEG C higher than that of the first polymer, and the average particle size is 100-300 nm. Said dispersion is useful for preparing environmentally friendly paints.
Dispersion aqueuse de particules de polymère comprenant au moins un premier polymère et au moins un second polymère mutuellement incompatibles. Le premier polymère est non-réticulé, possède une température de transition vitreuse de -25° à +0 °C et représente de 40 à 65 % en poids des particules, le second polymère est non alcalino-soluble et non-réticulé, possède une température de transition vitreuse de 5° à 40 °C et représente de 60 % à 35 % en poids des particules, la température de transition vitreuse du second polymère dépasse de moins de 40 °C celle du premier polymère et la dimension moyenne des particules est comprise entre 100 et 300 nm. Application à l'obtention de peintures respectant l'environnement.
