Zusammenfassung:	A microcrystalline talc particulate having a BET specific surface area no less than about 35 m2/g and one or both of: (a) a d50, by Sedigraph, no greater than about 2.0 5 µm; and (b) a d50, by laser, no greater than about 5.0 µm. L'invention concerne une particule de talc microcristallin ayant une surface spécifique BET égale ou supérieure à environ 35 m2/g et (a) un d50, mesuré par sédigraphe, égal ou inférieur à environ 2,05 µm et/ou (b) un d50, mesuré par laser, égal ou inférieur à environ 5,0 µm.
