Patent

CA 2410258

There is provided composite media and a method of producing them. The composite media contain a coalesced composite mixture of particles of an active ingredient (30) and binder particles (40). The binder particles preferably also fuse the composite structure to front (10) and back (20) substrates. The composite media also have stabilizing particles (50) that fuse with both the particles of an active ingredient and the substrates, thereby forming a composite medium according to the present invention.

Cette invention concerne des milieux composite et un procédé de fabrication y relatif. Les milieux composites renferme un mélange composite coalescé de particule d'un ingrédient actif (30) et de particules de liant (40). Ces particules de liant font de préférence fusionner la structure composite et des substrats avant (10) et arrière (20). Les milieux composites renferment également des particules de stabilisation (50) qui fusionnent à la fois les particules de l'ingrédient actif et les substrats pour former le milieu composite selon l'invention.
