Abstract:
In the present invention a composite particle including: a first polymeric particle having a diameter of from 100 nm to 3.5 microns including a core and a shell: the core including, when dry, at least one void; and the shell polymer having a calculated glass transition temperature (“Tg”) greater than 50° C.; and a second polymeric particle disposed on the surface of the first polymeric particle, the second polymeric particle having a minimum film-forming temperature of greater than 20° C.; wherein the ratio of the diameter of the first polymeric particle to the diameter of the second polymeric particle is from 1 to 50; and wherein the ratio of the weight of the first polymeric particle to the weight of the second polymeric particle is from 0.1 to 40, is provided.
