Abstract

Activator formulations which contain copolymers of (meth)acrylonitrile, styrenes, acrylates and/or unsaturated acids as binders are excellently suitable for preparing nonmetallic substrate surfaces for electroless metallization. The metal deposits produced are notable for good bond strength.
