<p>Metallizing objects which have at least two different plastics on the surface, comprises: (a) etching of the objects with an etching solution; (b) treating the objects with a solution of a colloid or with a solution of a metal compound, the metal being a metal of Group VIIIB or IB of the Periodic Table of the Elements; and (c) electrolytically metallizing the objects with a metallization solution. Metallizing objects which have at least two different plastics on the surface, comprises: (a) etching of the objects with an etching solution; (b) treating the objects with a solution of a colloid or with a solution of a metal compound, the metal being a metal of Group VIIIB or IB of the Periodic Table of the Elements; (c) electrolytically metallizing the objects with a metallization solution, the method further comprising subjecting the objects to ultrasonic treatment during a treatment in an additional method step performed after performing method step (b) and before method step (c), not however in electroless depositing of metal, to avoid Metallization of at least one first plastic exposed on the surface of the objects while at least one second plastic exposed on the surface of the objects is metallized.</p> |
