摘要:
A mild and simple process of activating substrate surfaces for the purpose of currentless metallization comprises using organometallic compounds of elements of the groups 1B and 8 of the Periodic System of Elements whose organic moiety has at least one functional group over and above the groups required for binding the metal are used for activation.
摘要:
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.
摘要:
The firmly adhesive metallization, in particular partial metallization, of the surface of semiconductors is possible, without pickling, by carrying out the activation with organometallic compounds of metals of the I and VIII Secondary Groups of the Periodic Table of Elements, then reducing in a conventional manner and metallization without current.

摘要:
Complex compounds of elements of sub-groups 1 and 8 of the periodic table in oxidation stages 1-4 with unsaturated ketones of the formula ##STR1## wherein R.sub.1 and R.sub.4 denote alkyl, cycloalkyl or aryl andR.sub.2 and R.sub.3 denote hydrogen or alkyl, are outstandingly suitable for activating substrate surfaces for electroless metallization since these complexes are distinguished by a high storage stability. The palladium complexes of but-3-en-2-one and hept-3-en-2-one are preferred.

摘要:
Black-metallized substrate surfaces which are characterized by the fact that they reflect at most 20% of electromagnetic radiation within the wavelength range from 200 to 5,000 nm and at least 50% within the wavelength range from 7,000 to 24,000 nm, the percentages being relative to the mean value over the entire wavelength range in each case, and which can be used as sunlight collectors are obtained by metallizing activated substrate surfaces without current in metallizing baths which contain a polymeric surface-active compound.
摘要:
Conductor boards with well adhering conductor tracks are obtained if the substrates, which are clad on both sides with copper foils, have said cladding removed chemically or mechanically, are activated, if necessary sensitized, and are provided with a 0.05-2.0 .mu.m thick layer of nickel, cobalt, manganese, a nickel/iron or nickel/cobalt mixture in an electroless metallizing bath, a 0.5-5.0 .mu.m thick copper layer is applied in a subsequent copper bath and the conductor pattern is then built up by the standard semi-additive methods.
