In Vesikeln verkapselte Aktivatormetalle und Verfahren zu deren Herstellung

WO 200177410 A UPAB: 20020308 NOVELTY - In vesicles filled with a metal cluster suspension or ionogenic metal activator and/or coated with metal clusters on their outer surface, the metal of the activator or cluster is selected from tin, noble metals and transition metals and the vesicles have an outer membrane of amphiphilic substance, preferably in a double layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) the production of the vesicles; (b) the production of vesicles containing a metal cluster suspension; (c) the production of vesicles coated with metal clusters. USE - The vesicles or vesicle suspensions are used as printing paste for selective activation of surfaces for metallization (claimed). They are useful for continuous or discontinuous production of thin metal films on substrates. ADVANTAGE - These metal colloids (clusters) or ionogenic activators for metallization can be converted to printing pastes of suitable viscosity. The pastes or precursors have good storage stability
