MICROPARTICULES POLYMERIQUES |
摘要 |
The invention relates to microparticles having a polymeric envelope, and to aqueous dispersions comprising said microparticles. The microparticles with a polymeric envelope comprise: a) at least one HASE-type acrylic copolymer; b) at least one solid-liquid phase-change material having a phase transition temperature Tf1 which is higher than or equal to 20°C; c) at least one solid-liquid phase-change material having a phase transition temperature Tf2 which is lower than or equal to 30°C, on the condition that Tf2 is lower than Tf1; and d) optionally at least one active agent. |
