Abstract
Abstract A simple and mild method of activating substrate surfaces for currentless metallization involves activating by means of organometallic compounds of elements of the 1st and 8th sub-Groups of the Periodic Table of Elements in which the organic moiety consists of oligomeric, prepolymeric or polymeric compounds containing double bonds.
