Abstract
The invention relates to an aqueous dispersion of polymer, based on structured polymer particles, said particles comprising a core polymer phase, based on a polymer P1 with Tg1 ranging from 60 to 120° C., a second polymer phase enveloping said core, based on a polymer P2 with a Tg2 ranging from −60 to 40° C. and a third outer polymer phase (or shell) based on a polymer P3, with a Tg3 ranging from Tg2−5° C. to Tg2+5° C. and having an Mn not exceeding 150 000, with the weight contents of said polymers P1, P2 and P3 being, relative to the total weight of polymer (P1+P2+P3): P1 from 5% to 60%, P2 from 40% to 85%, P3 from 5% to 25% with the sum of said weight contents being 100%.
